Question

question 10 of 10
which neurotransmitter is used for skeletal muscle movement?
serotonin
gaba
epinephrine
acetylcholine

Explanation:

• Serotonin: Regulates mood, sleep, etc., not skeletal muscle movement.
• GABA: Inhibitory neurotransmitter, mainly for reducing neuronal excitability, not for skeletal muscle movement.
• Epinephrine: Involved in the "fight - or - flight" response, affects heart rate, blood pressure, etc., not directly for skeletal muscle movement.
• Acetylcholine: Released at the neuromuscular junction, binds to receptors on skeletal muscle cells, and triggers muscle contraction.

Answer:

Acetylcholine
