In regards to excitation-contraction coupling, what does the action potential propagate along when it reaches the muscle?
Question
Solution 1
When the action potential reaches the muscle, it propagates along the sarcolemma. The sarcolemma is the cell membrane of the muscle fiber. From the sarcolemma, the action potential travels down into the muscle fiber through structures called T-tubules (transverse tubules). These T-tubules are invagi Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
