The neurotransmitter released at the NEUROMUSCULAR JUNCTION is:
AAcetylcholine (Ach) at the motor end plate
BGABA (chief inhibitory neurotransmitter)
CDopamine (involved in reward and motor)
DSerotonin (regulates mood and sleep)
Answer & Solution
Correct answer: A. Acetylcholine (Ach) at the motor end plate
ACETYLCHOLINE (Ach) is released at the neuromuscular junction by motor neurons
binds nicotinic ACh receptors on muscle, triggering contraction.
GABA + glycine = inhibitory (CNS).
Dopamine = reward/motor; serotonin = mood.
