Neurotransmitter, any of a group of chemical substances released by neurons to stimulate other neurons or muscle or gland cells. Signaling by neurotransmitters allows impulses to be passed from one cell to the next throughout the nervous system. Learn more about the types and functions of neurotransmitters.

Other neurotransmitters increase the positive charge so make the neuron more likely to fire. Neurotransmitter Co-existence (Dale principle) Some neurons in both the PNS and CNS produce both a classical neurotransmitter (ACh or a catecholamine) and a polypeptide neurotransmitter. They are contained in different synaptic vesicles that can be distinguished using the electron microscope. The traditional models for the study of neurotransmitter release are either the neuromuscular junction of the frog, crayfish, and rat or the giant synapse of the squid. These synapses are relatively simple in their structure, with a single axon terminal forming an identifiable synapse at the postsynaptic membrane of a muscle fibre or neuron. A neuron may have many thousands of dendrites, but it will have only one axon. The fourth distinct part of a neuron lies at the end of the axon, the axon terminals.

On the receiving end, only certain types of neurons can receive these chemical signals. is that neuron is (cytology) a cell of the nervous system, which conducts nerve impulses; consisting of an axon and several dendrites neurons are connected by synapses while neurotransmitter is (biochemistry|neuroscience) any substance, such as acetylcholine or dopamine, responsible for sending nerve signals across a synapse between two neurons. A neurotransmitter is a chemical messenger released from the nerve ending of a neuron to communicate with with adjacent neurons.

In healthy individuals, the neuronal signal moves rapidly down the axon to the terminal buttons, where synaptic vesicles release neurotransmitters into the synapse

GABA is the primary inhibitory neurotransmitter, which means it decreases the neuron's action potential. When the action potential drops below a certain level, known as the threshold potential, the neuron will not generate action potentials and thus not excite nearby neurons. The nucleus of a neuron is located in the cell body.

There are three classes of neurons: Sensory neurons carry information from the sense organs (such as the eyes and ears) to the brain. Characteristics of a neurotransmitter include its synthesis in the neuron, concentration in membrane-enclosed vesicles at presynaptic terminals, release by neuron terminal depolarization, induced activity at the postsynaptic terminal as a consequence of receptor binding, and removal from the synapse to terminate this effect. Nitric oxide was identified as a biological intercellular messenger just over 20 years ago, and its presence and potential importance in the nervous system was immediately noted.
