Synaptic Cleft

The synaptic cleft is a minuscule gap separating two adjacent neurons and serves as a critical site for intercellular communication. When an electrical signal reaches the terminal buttons of an axon, synaptic vesicles release neurotransmitters into this space. These chemical messengers travel across the synaptic cleft and bind to corresponding, matching receptors on the dendrite of the adjacent neuron.
