Detailed explanation-1: -The neurotransmitters are released into the synaptic cleft (synapse) by exocytosis. They bind to the receptors on the surface of the dendrite of the postsynaptic neuron. Neurons transmit nerve impulses by means of electrochemical signals and neurotransmitters.
Detailed explanation-2: -Neurotransmitter release occurs through the process of regulated exocytosis, in which a synaptic vesicle releases its contents in response to an increase in calcium. The use of genetic, biochemical, structural, and functional studies has led to the identification of factors important in the synaptic vesicle life cycle.
Detailed explanation-3: -At nerve terminals, neurotransmitter release is mediated by exocytosis of synaptic vesicles at active zone. After exocytosis, vesicular components are efficiently retrieved by endocytosis.
