Function of presynaptic terminals

WebNeurons communicate with one another at specialized contact sites called synapses, composed of pre- and postsynaptic compartments. Presynaptic compartments, or 'boutons', signal to the postsynaptic compartment by releasing chemical neurotransmitter in response to incoming electrical impulses. WebGlutamate is secreted by the presynaptic terminals in many of the sensory pathways. Glutamate is the principle excitatory neurotransmitter of the CNS. Serotonin (or 5-hydroxytryptamine) acts as an inhibitor of pain pathways in the spinal cord, and an inhibitor action in the higher regions of the nervous system. Serotonin is involved in mood control, …
