Sleep plays a vital role in good health and well-being throughout your life. Getting enough quality sleep at the right times can help protect your mental health, physical health, quality of life, and safety. The way you feel while you're awake depends in part on what happens while you're sleeping.
Receptors for the various neurotransmitters are located on both the presynaptic and postsynaptic nerve terminals of the neuron.
A neurotransmitter is a chemical messenger that carries, boosts, and modulates signals between neurons and other cells in the body. In most cases, a neurotransmitter is released from the axon terminal after an action potential has reached the synapse. The neurotransmitter then crosses the synaptic gap to reach the receptor site of the other cell or neuron.
