Alison, Bruce: Two Genders with a Common Identity

Alison, Bruce Two Genders with a Common IdentityIvory Coast is a west African country where homoeroticism is none acknowledged. compensate though it is practiced by a minority, they baffle to defy it secret. Fun Home is ab step to the fore identity. In a tragicomic tone, Alison Bechdel transcends both secrets in her autobiography. These secrets argon ab reveal gender and identity. Fun Home is home to a special family, an old artistic creationificer Bruce Bechdel and his family. This family is non ordinary. After Bruces death, which his daughter Alison, considers cosmos a suicide, his homo versedity is discovered. Alison believes her set outs suicide might be due to the declaration of her lesbianism. She has a popular past with Bruce they both shake off been hiding the truth about their gender preference. Bechdel uses the art of allusion to describe a complex relationship between Bruce and Alison. She says, In our particular reenactment of this mythic relationship, it was n ot me but my father who was to plummet from the sky. (Bechdel 4). Through this metaphor, Alisons situation is the foreign to the real story, the daughter should have been the one to plunge. It is an unusual situation describing two characters, where Bruce is a man and he likes men. Alison is a woman but she prefers females. Physically and emotionally, Bruce and Alison roll in the hay distance. Yet, beingness gay they both had much in common.Physically, Alison was distant from Bruce. She starts her autobiography with an im duration of herself with her father playing the Icarian Games. With this game, Alison presents one of the few physical contacts with her father. The author alludes to her father as being both Icarus and Daedalus, an ultimate artist who sees his children as hold outing materials. Bechdel says, Daedalus, too, was in divers(prenominal) to the human cost of his project (Bechdel 11). This aspect of the book limns the lack of attachment establishing a gap between f ather and daughter. It too describes a complicated relationship between these two characters, characterized by an obstinate Bruce forgetting family affection.Not only physical, this climb-down was overly emotional. Alison early suspects the sexual identity of her father. Seeing her father using a bronzing stick was proof that he belonged to a different moral value-system from the norm. Bruce was gay but to further complicate the situation he preferred teenagers. Bruce had a secret relation with Roy, his yardwork assistant/baby-sister. These two characters were opposite, Alison feeling comfort adequate with minuscule hairs and male attitudes, sees her father as a feminist. During an interview on the NPR radio, Bechdel says, Its like one of the first things I remember is wanting to wear boys clothes and scrap with my dad about it. (NPR). She was prevented from expressing her masculinity. Bechdel illustrates this aspect in a discussion between Alison and her father when Bruce say s, I dont c be Next time I see you without it, convalescent wale you. (Bechdel 97). Holding his daughter away from her desires, Bruce creates more(prenominal) distance than there was already.Despite being distant Alison and her father scrap of ground alikeities, they both had a secret. This dissimilarity from Bruce pushes Alison into more understanding of her father. In the quest to reconstruct her fathers history, m any common aspects show up. After the brutal death of Bruce, that Alison alludes as a queer in e very(prenominal) sense of that multivalent word, she unveiled her fathers secret. Bechdel emphasizes the detection of this secret by a sensual picture of Roy in the book. She says, Its low-contrast and out of focus. But the subject is understandably our yardwork assistant/babysitter, Roy (Bechdel 100). The picture has a double effect in the book. Certainly, it shows the evidence of Bruces sexual identity but it also characterizes the sexual longing of Alison. Watson i n her abstract of fun home says, The drawn photo is surrounded by elongated dialogue tags that chronicle Bechdels conicted responses, acknowledging both her identication with her fathers erotic desire for the aesthetic nonsuch of the boys body, and her distanced critique as a sleuth of this evidence of his secret life. (Watson 41). Still in the 1970s homosexuality was to be hidden in the society. Bruce was keeping his sexual preference secret. Alison was in the same situation too. In a business trip to Philadelphia, they met a woman dressed like a man who had a short haircut. Alison was amazed, but when her father asked her if she wants to be like this woman, she answered no. But her true answer would have been yes. She kept her sexual identity secret.Furthermore, the secret they several(prenominal)ly had, was about their identity. Like Bruce, Alison was gay. She developed her masculine traits early in her teenage years. Alison says, Indeed, I had perish a connoisseur of mascul inity at an early age (Bechdel 95). At a young age, she was a non-practicing lesbian. Yet she sh ars this same reality with her father. In a brisk Times article, Gustines says, Shes a lesbian, and sexuality looms large in her memoir. Bechdels father, Bruce, was gay (as she puts it a manic-depressive, closeted fag), and Fun Home is at its heart a story about a daughter trying to understand her father finished the common and unspoken bond of their homosexuality (Gustines). Obviously, Alison and her father had this identity in common, they were both homosexuals.In addition to sharing a similar identity, Alison also had common interests with Bruce. Watson in the description of Bruce Bechdel says, Bechdels story about the guessing of Alisons childhood memories not only links her sense of her own sexuality to her fathers secret gay side, it also produces a recognition about how their lives are linked over generations (Watson 42). From Watsons analysis, there is this aspect of their lif e that connects them. This connection is emphasized when Alison in Bruces twelfth-grade class. They were so consumed by similar thoughts and readings that the class was mostly animated by only Alison. She says, Sometimes it was as if Dad and I were the only ones in the room. (Bechdel 199). As if to confirm their similar identity, Bruce clear-cut to bring his daughter to the film. During their revelation one to another, Bechdel states, It was more like fatherless Stephen and sonless bloom (Bechdel 221). This particular moment opens the barrier between these two characters. For the first time, they share unreservedly their sexual orientation.In many places, especially in West Africa, it is almost impossible for homosexuals to express their identity. The subject of homosexuality is still taboo in some parts of these countries. Through her novel, both tragic and comic, Bechdel draws attention about this particular topic. She shares this theme about homosexuality represented through Ali son and her father. These characters struggling to guard an intense connection. However, they share similarities. Certainly, this family is more complicated relation because father and daughter share an identity not acknowledged. Fun Home comes out of the ordinary because it touches a sensitive subject that concerns the whole society.Work CitedBechdel, Alison. Fun Home A Family Tragicomic.

Unlike skeletal and cardiac vim cells, smooth brawn cells are not striated, and have single nuclei. Smooth vigors are typically under control of the autonomic nervous system, and do not contract voluntarily. Smooth tendon contracts slowly, and does not represent the characteristic twitch seen in skeletal tendon. In addition, smooth muscle is not prone to muscle fatigue, making it an ideal component of sphincter muscles. Smooth muscle is found in the gastrointestinal tract of many animals, and is responsible for peristaltic movements.Smooth muscle condensations are touch on by calcium and potassium ions. atomic number 20 ion influx into the smooth muscle cell initiates a contraction. Potassium ion concentration in the extra cellular medium affects the resting mem brane potential of the cell, bringing it nearer to or farther away from its threshold voltage. Neurotransmitters affect different types of smooth muscle differently, depending on the association of the smooth muscle with excitable cells. In general, acetylcholine step-ups the muscle cells permeability to calcium, while epinephrine decreases the cells permeability to calcium.Introduction and aim of the examineThe following report was to test a smooth muscle which was collected from the catgut of a rabbit. The main of this try out was to see how the surrounding surroundings of the muscle could affect how muscle contracted. The experiment consisted of different environments and the muscle was monitored and moderates were recorded of the bounteousness and the relative frequency of the draw inlengths. The levels of muscle contractions and relaxations were measured using a transducer, a D.C amplifier, and a laboratory calculating machine.Overview of experimentThe smooth muscle w as a gloomy part of the catgut which was prepared correctly by trimming off the attached mesentery and fat. This experiment only required one piece of this smooth muscle and this was then placed into a beaker which was aerated and fed Ringer-Locke solvent this is an aqueous solution containing the chlorides of sodium and potassium and calcium that is isotonic to animal tissues. The experiment only required one piece of small intestine, which had the length of 2-3 cm long. The intestine was held in place with a tissue holder, and was attached to the transducer via a piece of string. The transducer detected contractions and relaxation of the muscle, and via the D.C amplifier showed on the computer the frequency and strength of the contractions and relaxations. The solution that the muscle was placed in was kept at the temperature of 37 Celsius apart from when the environment condition miscellanead was the temperature. This type of setup is know as in vivo preparation. This prepara tion of the smooth intestine allows a precise control of the environmental conditions.Brief description of test carried outThe test which was carried out had six parts to it. The first part of the experiment was to actualise initial control of the muscle this was done by having optimum conditions for the smooth muscle so it could achieve a steady rate of contraction and relaxation. This was achieved by adding Ringer-Locke solution and keeping it aerated. By having this set up it allowed the muscle environment to be very closely met to the ideal body environment where the muscle would have a good contraction and relaxation rate. The muscle was left in this preparation until the readings on the computer were constant (about 4 transactions) the initial control was tagged using the comment bar.The next environment was non-aerated this meant to turn the air supply off which was climax to the bath where the muscle was held. Then the Ringer-Locke solution was removed from the bath and f resh Ringer-Locke solution was then placed into the bath. The reason for removing the old solution was to prevent any inaccurate readings as the solution could still have contained oxygen which would have affected the results. This part of the test was recorded after every 5, 10, 15 minutes and the results where inserted into a table. The main train of using this environment was to see what the muscle contractions and relaxations are when there is a lack of oxygen. This part of the experiment was again labelled on the comment bar.The next part of the experiment was to remove the Ringer-Locke solution and replace it with 50ml of glucose slack solution and again results were recorded after every 5 ,10, 15 minutes and recorded into a table.The fourth different environment was change in temperature. The Ringer-Locke solution of 37 Celsius was replaced with a Ringer-Locke solution that was cooled to 4 Celsius. The purpose of this environment was to test the muscle activity in a cold en vironment and to analyse the effects.The fifth environment involved the use of calcium free solution this replaced the Ringer-Locke solution. This was analysed for 5 minutes to see how the muscle activity was affected.The final environment was to do with changes in the pH. The pH was changed from pH7 which is neutral to a different pH. The solution with different pH was prepared before hand and the purpose of this environment was to see what effect a pH change would have on the muscle activity.After each part of the experiment initial control was established before moving on to the next part the reason for this being to keep the muscle running properly before each part of the experiment and to cause less damage to the smooth muscle. Also each part of the experiment was labelled on the comment bar this was done to show each different part clearly so it was not confused. (Clear methods are shown in the printouts)To work out the amplitude of the graph recording two figures were recorde d one being the peak of the wave and the other being the lowest part of the waveTo work out the frequency for each part of the experiment the amount of waves were recorded in a minute time period. The frequency in this fictitious character was how many times the muscles contracted and relaxed in a minutes. The amplitude was the strength of each contraction and relaxing of the muscle. The maximum and minimum amplitudes were collected for each environment and recorded the amplitude chosen was picked at random as well as the minute where the frequency of waves was calculated.Discussion of resultsFirstly a diagram of the intestine is needed to show how it works and what different types of cells it contains. This is needed as it will help to understand why the muscle behaved differently when tested with six different environments. A diagram of the small intestine is shown belowThe small intestine contains the 4 basic layers which are serosa, muscularis, submucosa, and mucosa.Small intes tine wall is composed of the same four layers that make up most of the gastrointestinal tract serosa, muscularis, submucosa, and mucosa. The mucosa is composed of a layer of epithelium, lamina propria, and muscularis mucosae. The epithelial layer of the small intestinal musoca consists of unanalyzable columnar epithelium that contains many types of cells. Some of these are the followingEnetrocytes these help with the transport of substances from lumen of the intestine to the circulatory system, synthesis of the glycoprotein enzymes needed for terminal digestion and absorption. goblet cells these are unicellular mucin also known as secreting glands.Paneth cells these are located at the bottom of the intestinal glands. Their main voice is their secretion of granules which contain muramidase this enzyme helps breakdown bacteria also known as phagocytosis. Paneth cells may have a role in regulating the microbial population in the small intestine.Enteroendocrine cells these are mos tly found again in the trim parts of the intestinal gland known as the crypt. The main function of these cells is to release several hormones. The main one beings cholecystokinin, secretin and gastric inhibitory peptide these help increase pancreatic and gallbladder activity.Intermediate cells these are young enterocytes and goblet cell which are able to withstand cell division.Apart from the smooth muscle many other cells and vessels make up the intestine. The small intestine also contains submucosal artery and vein, lymphatic vessel, submucosal plexus, bankers bill layer of smooth muscle, and myenteric plexus. All these tissues, cells, and vessel combine to make the small intestine wall.The smooth muscle in the control environment was able to get under ones scrape up a steady frequency through out its 4 minute period with 15 waves per minute. The waves which were seen were the smooth muscle contracting and relaxing. The amplitude levels of the waves were both rather high sho wing real contractions rate the reason for this was that the environment set was to ideal conditions where the muscle could perform its best. It had a max amplitude of 2.10 and min amplitude of 0.78 which shows that having ideal conditions the muscle is able to behave normally without any problems.The effect of oxygen lack of the smooth muscle cause the small intestine to increase the frequency, at 5 minutes no aerated the frequency had first dropped to 13 and after 15 minutes the frequency of contraction and relaxations had increased to 17 the reason or this being without oxygen the smooth muscles started to have spasms as it was unable to contract properly without the oxygen supply needed. Also the amplitude levels fall quite quickly from 1.94 (max) and 0.47(min) at 5 minutes to 1.58(max) and 0.38 (min) at 15 minutes. The reason for this was that without oxygen the muscle was unable to make the competency needed for strong contractions as the peak is lowered as can be seen on t he traces. This was detected by the pull on the string that was attached to the transducer the pull was not as strong so this was recorded on the traces. So without oxygen the muscle cells are still able to make adenosine triphosphate but a small amount. Only about 2 ATP are produced per molecule of glucose in glycolysis. If there is no oxygen present, the Pyruvate produced in glycolysis undergoes fermentation to regenerate the nicotinamide adenine dinucleotide+ used in glycolysis. This is known as anaerobic respiration, anaerobic respiration generates only two ATPs, and lactic acid is produced. Most lactic acid diffuses out of the cell and into the bloodstream and is subsequently absorbed by the liver. Some of the lactic acid remains in the muscle fibers, where it contributes to muscle fatigue. Because both the liver and muscle fibers must convert the lactic acid back to pyruvic acid when oxygen becomes available, anaerobic respiration is said to produce oxygen debtThe next part of the experiment was to test how the muscle activity differed when placed in glucose free solution. From this part of the test the frequency of muscle activity stayed consistent throughout the 15 minutes. The traces show consistent movement and also the amplitudes levels differed as at 5 minutes (1.34) the maximum amplitude was low then at 10 minutes (1.51) it annoyed higher and at 15 minutes (1.37) it decreased again to a similar figure which was at 5 minutes. By looking at this result the results are not as accurate as they should have been, meaning they may have been some kind of inaccuracy when following the method as without glucose, ATP can not be made and the amplitude of the waves should have been lower.ATP can be made from glucose which is stored in the carbohydrate glycogen. Through the metabolic form of glycogenolysis, glycogen is broken down to release glucose. ATP is then generated from glucose by cellular respiration. Also ATP can be produced from glucose and fatty ac ids obtained from the bloodstream. When energy requirements are high, glucose from glycogen stored in the liver and fatty acids from fat stored in adipose cells and the liver are released into the bloodstream. Glucose and fatty acids are then absorbed from the bloodstream by muscle cells. ATP is then generated from these energy-rich molecules by cellular respiration. Without glucose the frequecny should hve increased but the amplitudes levels should have decreased as there was not a sufficient energy source which could supply the muscle so it could contract and relax.The next part of the experiment consisted of placing the smooth muscle into a cooled solution of 4 Celsius from a change of 37 Celsius. There was not much change to the frequency but it did drop a little bit due to the muscle not being used to these environmental conditions. The amplitude differed from the control readings as they had decreased but were still quite high as they had the nutrients in the solutions which h elped them to contract. If this experiment was left to deport on then there would be further change as the solution would gradually heat up to room temperature and this would mean that the smooth muscle activity would increase.Calcium plays a big part in all muscle contraction as well as smooth muscle contraction which is different as it does not contain troponin. In smooth muscles calcium ions enter from outside the cell. They then bind to an enzyme complex on myosin this then breaks up ATP into ADP and then transfers the Pi directly into myosin. By doing this it allows the myosin to activate and from cross ridges with actin. When the calcium is pumped out of the cell, the Pi gets removed from myosin by an enzyme this allows the myosin to become inactive and the smooth muscle is able to relax. This process is also known as myosin regulated contraction.In the experiment where calcium free solution was added it affected the smooth muscle immensely as the frequency of contracting and relaxing dropped to 12. Also the amplitude levels came down as the contractions and relaxations levels were not strong the max being 0.95 and the minimum being 0.47 if this was left for a longer period of time the frequency levels may have dropped more. Without calcium entering the cell the smooth muscle is unable to do the process which is described above. While making the Ringer-Locke solution it is not only the calcium ions which are important to the smooth muscles. Some others are potassium chloride and sodium chloride, the reason these ions are needed because it helps to portray an environment such as the body with ideal conditions. If only distilled water was used it would mean the cells in the muscles would up take the water and blow up. So these ions are used so they are able to keep a concentration side and allow everything to work correctly as it would in the smooth muscles natural environment.The final environment was the change in pH levels. The results showed that the muscle had stopped work and there was no reading on the traces. This meant that there was no muscle contraction or relaxing. The reason for this was the muscle had broken down the reason for this muscle fatigue was that the low pH had affected the smooth muscle as it was unable to perform in this type of environment. Also as the low pH solution was there for a certain period of time the muscle was unable to remove it and therefore caused the muscle to breakdown. The low pH may have affected the sarcoplasmic reticulum which may lead to the interfere of the intercellular calcium concentrations, this can lead to long term physical muscle damage as muscle fibers are affected.While preparing the isolated smooth muscle many precautions are taken so the muscle can avoid excessive pH changes. One of these precautions which are taken is to make sure that before inserting the small intestine into the bath. The solution will need to be tested with pH indication test strips which will give a fairly accurate reading of the solution which the smooth muscle will be placed. This is very important as if the pH is incorrect it will mean that the smooth muscle will not perform to its full potential meaning the results achieved will be inaccurate. To gain accurate results all solutions which are used will need to be checked to see if they are the correct pH by using the ph indicating strips. After this test the smooth muscle was unable to reach the control again as the muscle had broken down.If this experiment was done again at room temperature the results would differ as the performance of the muscle would decrease. This is because the optimum temperature inside the body is around 37 Celsius and this temperature allows the muscle to work at an optimum rate. The lower temperature will mean that muscle contraction will be slower as there will be an effect on enzyme receptions as the more heat there is the more kinetic energy there is this will mean that the muscle activity wil l be good.If acetylcholine was added to the solution bath of the smooth muscle the membrane potential would decrease and the frequency of waves would increase. The muscle will become more active, with an increase in tonic tension and the number of cadent contractions. The effect is mediated by enzymes which increases the intracellular Calcium concentration. Another substance which could have been added was adrenaline. Adrenaline allows blood to flow more easily to your muscles. This means that more oxygen is carried to your muscles by the extra blood, which allows your muscles to function at elevated levels. Adrenaline also facilitates the conversion of the bodys fuel source (glycogen) into its fuel (glucose). This carbohydrate gives energy to muscles, and a sudden burst of glucose also allows muscles to strengthen further.Skeletal and smooth muscle muscles differences in structure and functionThere are many differences between the two types of muscles the differences are stated be lowSnmooth musclesSkeletal muscleA smooth muscle fiber has no T tubules, and the sarcoplasmic reticulum forms a loose profit throughout the sarcoplasm.Are long cyrindrical cells that contain many nucleiSmooth muscle tissue has no myofibrils or sarcomeresThey are striated this shows their precise alignments of their myofilaments.This tissue also has no striations and is called nonstriated muscle.Thick filaments consist of myosin as thin filaments consist mostly of actin.Thick filaments are scattered throughout the sarcoplasm of a smooth muscle cell separately independent cell is stimulated by a motor neurone.Adjacent smooth muscle cells are bound together at dense bodies, convey the contractile forces from cell to cell throughout the tissue.Connective endomysium seprates cellFunction DifferencesSmooth muscles cells are an involuntary action and can work slower so they do not have muscle fatigue.Skeletal Muscle contains both Fast Slow Twitch muscle fibers, that allow for a faster r eaction where needed, and the opposite is true for the Slow as wellSmooth muscle lines your arteries and airways and serves to contract or relax to help control blood pressure.skeletal muscles function almost continuously to maintain your posture making one tiny adjustment after another to keep your body uprightThey are also present in the iris of the eye to control the size of the pupil in response to light. By the use of the radial and circular muscle.Skeletal muscle is also important for holding your bones in the correct position and prevents your joints from dislocating. Some skeletal muscles in your face are directly attached to your skinThey line the GI tract to move food through the intestines. This is done by peristalsis.Skeletal muscle generates heat as a by-product of muscle activity. This heat is vital for maintaining your normal body temperature.
