Question

what is neurotransmitter? Describe the origin of the neurotransmitter and its functions at the synapse

Answer 1

Ans) Neurotransmitters are endogenous chemicals that enable neurotransmission. It is a type of chemical messenger which transmits signals across a chemical synapse, such as a neuromuscular junction, from one neuron (nerve cell) to another "target" neuron, muscle cell, or gland cell.

Neurotransmitters are released into and diffuse across the synaptic cleft, where they bind to specific receptors on the membrane of the postsynaptic neuron. .In response to a threshold action potential or graded electrical potential, a neurotransmitter is released at the presynaptic terminal.
