Endogenous Neurotransmitter Release

Meaning

The natural, internal physiological process by which a neuron synthesizes, stores, and subsequently discharges chemical signaling molecules, known as neurotransmitters, into the synaptic cleft in direct response to an action potential. These essential molecules then successfully transmit signals to adjacent neurons, muscle cells, or glands, thereby driving all aspects of neurological and physiological function. This spontaneous yet tightly regulated release is the fundamental basis of communication within the entire nervous system.
