The skeletal muscle action potential is MOST DIRECTLY important for which process?
A) activating the DHP receptor
B) activating the ryanodine receptor
C) promoting cross-bridge formation
D) triggering neurotransmitter release

Question

Quizplus · Accepted Answer

The skeletal muscle action potential directly activates the DHP receptor, which is a voltage-sensitive receptor in the T-tubule membrane. This activation is crucial for the subsequent release of calcium from the sarcoplasmic reticulum, leading to muscle contraction.
