Muscle Memory Essay

Rationale, Significance and Hypothesis. An extrinsic factor, which exerts a dominant influence on skeletal muscle fiber phenotype, is the nervous system. Buller et al. (1960) elegantly demonstrated the plastic nature of skeletal muscle fibers in response to changes in innervation type. Later, Lφmo and Westgaard (Lφmo and Westgaard, 1974; Westgaard and Lφmo, 1988) demonstrated that depolarization of muscle with specific patterns and frequencies of electrical activity are sufficient to cause changes in mature muscle fiber phenotypes. However, how myofibrillar gene expression and structural organization is affected by the frequency of impulses during activity, the amount of activity over time, or other characteristics of patterned activity is essentially unknown. To answer these questions will require the isolation and study of subsets of muscle-specific proteins in relation to different electrical activation patterns in vivo, an issue that cannot be easily addressed in preparations currently used in the study of muscle development and maintenance. However, using novel in vivo approaches can, in part, circumvent this difficulty.

Muscle contraction can be understood as the consequence of a process of transmission of action potentials from one neuron to another. A chemical called acetylcholine is the neurotransmitter released from the presynaptic neuron. As the postsynaptic cells on the muscle cell membrane receive the acetylcholine, the channels for the cations sodium and potassium are opened. These cations produce a net depolarization of the cell membrane and this electrical signal travels along the muscle fibers. Through the movement of calcium ions, the muscle action potential is taken into actual muscle contraction with the interaction of two types of proteins, actin and myosin.

On a Sunday after church lets out is when I decided to do to do my ethnomethodology experiment. I also brought my sister who is known for her sweet tooth. As we sit down at our table our slightly overweight waiter immediately greets us. We order chocolate milkshakes and our waiter smiles and says, “Wait! No lemon water this time?” This is the first reaction we received. It made me feel a little nervous because if he is already reacting to our drinks, how is he going to react to the rest of the dinner. After we receive our milkshakes we ordered our ice cream brownie delux. Our waiter laughs and asks if that would be all. I explain to him that we would still like an entree but that we want our dessert first. We then order a burger and some fries. He then warns us that we may start looking like him if we keep this up this diet. This made me uncomfortable because I was unsure how to respond

Nelson Mandela once said that “... courage was not the absence of fear, but the triumph over it. The brave man is not he who does not feel afraid, but he who conquers that fear. " Courage doesn’t mean that you are without fear, genuine courage is trying to achieve a goal, even though you’re afraid. In the novel, To Kill a Mockingbird by Harper Lee, Tom Robinson is an innocent black man accused of rape.

It was my first day on the job with Lyric. I was moderately eager to meet him. When I first encounter new clients, I do not know what to expect. I became accustomed to walking into people’s homes blindfolded without expectations. I knocked before I entered Lyrics home at 8PM that Friday evening. I was greeted by the CNA that I was releasing off of her shift. I quickly noticed that the room’s atmosphere radiated an aura of coffee. The smell was quite pleasant and homey. I could distinguish the scent of the coffee beans mixed with vanilla. The CNA stood in front of me as she informed me that Lyric had a great day. I put on my warming smile as I introduced myself to Lyric. He smiled at me and told me hello. After the other CNA left, I provided Lyric with my company and began to get to know him better. Lyric lived in a two-bedroom, two-bathroom suite. The sight of his room was pretty welcoming. The beige curtains matched up well with the brown carpet of the apartment. I ran my hands along the silk curtains as I closed them. The curtains felt so soft and delicate as if they were made from the same material of my silk black gown in my room closet. I sat down on the chair next to Lyric’s recliner that he was sitting in. I watched him as he thought out loud about schedule for the next

Thank God for people who notice things then follow through with appropriate action. He stood there, still looking good, eighty-five years old, thin and upright, completely bald, thinking a second before responding. Slowly, both of his eyebrows rose, wrinkling his forehead; a slow smile crossed his face and I knew he’d sorted the memory from the thousands of similar ones. I was sure he’d placed my name, face and the event in perspective. Then his eyes opened wider, rolling the wrinkles all the way to his bald head and he said, "You and that red haired Eric kid, you two wore the goofy colored shoes and

The articles by Erikson et al., Gatz, Korol et al., and Draganski et al. explore the concept of increased physical activity and/or mental activity having effects on the cognitive function and development or deterioration of the brain as we age. Although I agree that physical exercise is critical in increasing cognitive function because of the health benefits it provides, as well as the increased blood flow and circulation throughout the body, I ultimately believe that a healthy brain is not achieved solely by physical exercise or mental exercise, but both. I think there is a link between physical and mental exercise, and that the combination of these two activities creates higher cognitive functioning of the mind as well as the body. The mind and body come together and meet to make an overall healthy individual.

Marines are constantly being tested physically and mentally in their line of they must be prepared for any situation any scenario which is why they train so much and something that has been constantly drilled into they're head since day one is to train as if it were the real thing or always pay attention to the little details, never get complacent therefore it's important for every marine to train like it's game day to build that muscle memory so it's instilled into their brains for example when training on a field operation it is vital that the marine always has his weapon on him everywhere he goes no matter when or where that marine is going this is a way to build that muscle memory so that marine knows to always have that weapon to defend

Without any hesitation my thumb had hit the tiny blue send arrow box. I gently moved my phone to my bedside table and laid my head down against the hard pillow. My eyes had shut

I made a few more futile attempt at conversation before turning to the other guy who was sitting next me, the one who had agreed that the library chick was hot.
