What is the unstoppable electrical current that travels down the length of the entire surface of a sarcolemma?
A) neuromuscular junction
B) action potential
C) neurotransmitter
D) acetylcholine

Question

Quizplus · Accepted Answer

The unstoppable electrical current that travels down the length of the entire surface of a sarcolemma is known as an action potential. This is a result of the depolarization and repolarization of the membrane due to the flow of ions through voltage-gated ion channels. The neuromuscular junction, neurotransmitter, and acetylcholine all play a role in the process of muscle contraction, but are not the specific answer to this question.
