Question

multiple choice question
which neurotransmitter is responsible for skeletal muscle contraction?
-
norepinephrine
dopamine
acetylcholine
endorphins

Explanation:

• Norepinephrine is involved in the body's stress response and affects heart rate and blood pressure.
• Dopamine is associated with reward, motivation, and movement regulation (but not specifically skeletal muscle contraction).
• Acetylcholine is the neurotransmitter released at the neuromuscular junction to initiate skeletal muscle contraction.
• Endorphins are natural painkillers and mood - elevating chemicals in the body.

Answer:

Acetylcholine
