Question

question 40
the neurotransmitter that is responsible for stimulating skeletal muscle is:
a acetylcholine
b troponin
c calcium
d norepinephrine

Explanation:

Acetylcholine is a neurotransmitter that is released at the neuromuscular junction to stimulate skeletal muscle contraction. Troponin is a protein involved in muscle contraction but is not a neurotransmitter. Calcium is an ion that plays a role in muscle contraction but is not a neurotransmitter. Norepinephrine is a neurotransmitter involved in the sympathetic nervous system (e.g., "fight - or - flight" response) and is not the primary neurotransmitter for skeletal muscle stimulation.

Answer:

A. acetylcholine
