Question

Into what does the neuron release its neurotransmitter at the neuromuscular junction?

• A. motor end plate
• B. cytoplasm of the muscle cell
• C. cisternae
• D. synaptic cleft

Answer 1

The correct option is D

synaptic cleft

A microscopic gap called a synaptic cleft exists at the neuro muscular junction. When a nerve impulse arrives at the axon terminal of one neuron, a chemical substance called neuro transmitter is released through the presynaptic membrane, traveling in milliseconds across the synaptic cleft.
