Introduction:
The synaptic transmission or neurotransmission is a process by which neurotransmitters (signaling molecules) are released by the presynaptic neuron. Turning off the stimulus on time is also important like stimulating a postsynaptic cell. If not, the postsynaptic cell could continue to fire indefinitely, leading to changes in physiological coordination. So a molecule of a neurotransmitter binds only for 1 ms or so to its receptor, then separates from it. The two ways to stop the transmission process are stopping the neurotransmitter and removing the one which is already available. The former is achieved by cessation of signals in the presynaptic nerve fibers. The second is attained by neurotransmitter degradation, reuptake, and diffusion.
