What is Neurotransmitters?
A neuron releases a signalling chemical called a neurotransmitter across a synaptic gap to influence another cell. Any major body component or target cell that receives the signal may be another neuron, but it could also be a gland or muscle cell. In the synaptic cleft, where they can interact with receptors on the target cell, neurotransmitters are released from synaptic vesicles. The receptor that the neurotransmitter attaches to determines how the neurotransmitter affects the target cell. Numerous neurotransmitters are produced from easy-to-find, abundant precursors such amino acids, which are frequently converted in a limited number of biosynthetic steps.
