Acetylcholine receptors are concentrated at the entrances to the clefts.
WebThe axon terminal of the motor neuron connects to the muscle fiber via the neuromuscular junction (a synapse). The arrival of the action potential stimulates voltage-gated Ca 2+ channels in the axon's membrane to open, and Ca 2+ enters the axon terminal from the extracellular space. WebThe synapse at the neuromuscular junction has three characteristic features of chemical synapses in the nervous system. First, there is a distinct separation between the presynaptic and the postsynaptic membrane. The space between the two is known as the synaptic cleft.
