Transverse tubules
A)store sodium ions for the action potential at the cell surface.
B)transmit muscle impulses into the cell interior.
C)store calcium ions.
D)connect actin and myosin.

Question

Quizplus · Accepted Answer

Transverse tubules are specialized membrane structures that allow for the transmission of muscle impulses from the cell surface to the cell interior, which triggers the release of calcium ions from the sarcoplasmic reticulum and initiates muscle contraction. They do not store sodium ions or connect actin and myosin. While they are involved in the release of calcium ions, they do not store them.
