How would you explain muscle cell contraction were there no

How would you explain muscle cell contraction were there no T tubules?

How would you design the skeletal muscle differently if there were no epimysium, perimysium, or endomysium?

If skeletal muscle fibers could store large quantities of adenosine triphosphate (ATP), how would you explain the change, if any, in our ability to run at top speed for a distance (or to perform any anaerobic exercise)?

Solution

Ans) A T-tubule (or transverse tubule) is a deep invagination of the sarcolemma, which is the plasma membrane of skeletal muscle and cardiac muscle cells. T-tubules are the major sites for the coupling of excitation and contraction, which is chemical is withdrawn the cells rapidly expand before returning to their normal size.

Ans) Epimysium, a component in the structure of muscle and/or the attachment of skeletal. Skeletal Muscle ... There are usually many fasicles that form a single muscle: Epimysium. Epimysium (together with the perimysium and endomysium layers of epimysium should not be confused with other layers of connective tissue.
