Neurotransmitters are chemical messengers secreted by neurons that activate an adjacent cell. Neurotransmitters are secreted into a synaptic cleft, rather than into the bloodstream.

Morphology of a chemical synapse. (A) The presynaptic terminal and postsynaptic neuron are separated by a fluid-filled synaptic cleft. Note that the presynaptic terminal contains synaptic vesicles, which contain neurotransmitter and active zones. Receptors for the transmitter are located on the postsynaptic membrane. Different types of central nervous system synapses include (B) axodendritic synapse, (C) axosomatic synapse, and (D) axoaxonic synapse. (E) In a symmetrical synapse, the…

Chemical synapse. Chemical synapses are specialized junctions through which cells of the nervous system signal to one another and to non-neuronal cells such as muscles or glands.   A chemical synapse between a motor neuron and a muscle cell is called a neuromuscular junction. Chemical synapses allow the neurons of the central nervous system to form interconnected neural circuits.
