I’m working on a anatomy multi-part question and need guidance to help me learn.
Question 1: All cardiac muscle fibers (or cells) are functionally connected via intercalated discs. Explain why skeletal muscle fibers are NOT similarly connected, but are, instead, innervated according to separate motor units.
Question 2: Describe 2 places where facilitated diffusion occurs along the excitation-contraction pathway in skeletal muscle. Be sure to order your 2 examples according to the order they occur in the pathway (i.e. make sure the first that you discuss happens earlier in the pathway than the second that you discuss)
Question 3: Describe the hydrolysis of ATP to ADP, using the battery analogy found in the Sliding Filament Theory.
Question 4: Contrast hyperplasia & hypertrophy of anabolism, and describe which is undergone during exercise of muscle tissue.
Question 5: Does an acetlycholinesterase inhibitor lead to muscle relaxation? If yes, explain how. If no, explain how it leads to tetany.
Question 6: Describe two places in skeletal muscle where voltage-gated Ca channels are activated. Be sure to carefully explain the effect of the Ca released by the channels in each instance.
