The neurotransmitter in skeletal muscle contraction is ___________.
A) norepinephrine
B) actin
C) acetylcholine
D) tropomyosin

Question

Quizplus · Accepted Answer

The neurotransmitter in skeletal muscle contraction is acetylcholine. It is released at the neuromuscular junction and binds to receptors on the muscle fibers, causing depolarization and leading to muscle contraction. Norepinephrine is a neurotransmitter involved in the sympathetic nervous system and is not directly involved in skeletal muscle contraction. Actin and tropomyosin are proteins involved in muscle contraction, but they are not neurotransmitters.
