Chemical synapses are connections between two neurons or between a neuron and a non-neuronal cell (muscle cell, glandular cell, sensory cell). The synaptic complex is the non-reducible basic unit of each chemical synapse as it represents the minimal requirement for an efficient chemical synaptic transmission.
What happens at a chemical synapse?
At a synapse, one neuron sends a message to a target neuron—another cell. ... At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters. These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential.
Where are chemical synapses found in the body?
Synaptic vesicles are docked at the presynaptic plasma membrane at regions called active zones. Immediately opposite is a region of the postsynaptic cell containing neurotransmitter receptors; for synapses between two neurons the postsynaptic region may be found on the dendrites or cell body.
