Neurotransmitters Definition:
At most synapses, neurons secrete molecules called neurotransmitters that diffuse a very short distance and bind to receptors on the target cells.

Neurotransmitters Notes:
Neurotransmitters are endogenous chemicals messengers that enable neurotransmission. It is a type of chemical messenger which conveys signals across a chemical synapse, such as a neuromuscular junction or from one neuron to another destination neuron or any other target cell. Neurotransmitters are released from synaptic vesicles in synapses into the synaptic cleft, where they are received by neurotransmitter receptors on the target cells. Neurotransmitters play a huge role in shaping everyday life and functions. More than 200 chemical messengers have been distinctively recognised.
