WebNov 26, 2024 · The neuromuscular junction is a chemical synapse between the motor neuron and the skeletal muscle fiber. It consists of a presynaptic terminal, synaptic cleft, and a postsynaptic membrane or cell. Presynaptic Terminal In case of neuromuscular junction, the presynaptic terminal is an axonal terminal of a motor neuron. WebSynapses Where two neurons meet there is a small gap called a synapse. The plasma membranes of each neuron are in very close contact and are separated by a narrow space called a synaptic cleft....
