answer the questions below in at least 2 paragraphs.
A) Using chopsticks to eat a meal requires visual guidance, while swiping a metrocard at the turnstile cannot be easily corrected once initiated. How and to what extent, might you expect the neural control of these movements to differ?
b) Describe the basic molecular structure of a sarcomere, and explain what is the role of calcium and ATP in contraction. Use as a framework of explanation your understanding of the sliding theory of contraction.
Sarcomere are found in striated muscle cells. Striated muscle cells have transverse bands.Which gives them a striped appearance.Within a single muscle cell ,each cell contains hundreds of fibers which is called myofibril. Myofibril is arranged to have cross striations where sarcomere are present .Myofibril consist of major bands A bands which are darker in color, I bands that appear lighter in color between the bands are Z disc /Z line . Sarcomere are also present between the two Z disc.Myofibril consist of a longitudinal series of sarcomeres.The role in calcium
c) Make a comprehensive table comparing the different metabolic sources of ATP available to skeletal muscles.
Rubric:Read Student Assignment 5 and compose your answer using a word processor. In items a) and b) you are asked to explain two phenomena at different levels of integration. Feel free to include a drawing that helps you address what is asked. In item c) you are asked to create a table. You can draw the table by hand or use any software available to you. Insert the drawings and table in your text document and print or save in the pdf format. Go to the Discussions section of our Blackboard home page and upload your pdf file in the SA45forum.
Rubric: Part a). The main goal of this part is to evaluate your ability to apply your basic understanding of what neural control is. I expect that you will be able to think about the question and articulate a response in the form of a few text paragraphs and if applicable a drawing (4/11 points).
Part b). The main goal of this part is to evaluate your ability to explain the dynamic process of contraction. Keep in mind that you have several cartoons in your textbook to get inspired. You can write and including a drawing is your choice (3/11 points).
Part c). The main goal of this part is to evaluate your ability to summarize information. Creating tables can be useful way to convey complex information in a simple format (4/11 points).
A complete answer involves writing in paragraphs that articulate your ideas clearly and concisely; if drawing is involved, remember to indicate with brief text or labels what is meant by a symbol or a part.
