D) norepinephrine.

Question

Maddi Ketterer · Accepted Answer

Final Answer : C, Explanation :  Acetylcholine is typically involved in muscle movement and is the primary neurotransmitter released by motor neurons. The twitching Jeremy is experiencing in his leg is likely due to the release of acetylcholine at the neuromuscular junction, leading to small contractions in the muscle fibers. Serotonin and dopamine are not typically involved in voluntary muscle movement, while norepinephrine plays a greater role in the sympathetic nervous system's fight or flight response.
