The statement indicating that at a neuromuscular junction, acetylcholine has inhibitory effects is FALSE.

  • Acetylcholine is a neurotransmitter that exhibits different roles at different synaptic sites in the body.

  • Acetylcholine is released from motor neurons in order to modulate muscle contraction by binding specific receptors in the muscle cells.

  • Therefore, at a neuromuscular junction, acetylcholine has activatory effects.

In conclusion, the statement indicating that at a neuromuscular junction, acetylcholine has inhibitory effects is FALSE.
