synaptic cleft description
1 answer
The synaptic cleft is a small gap between the axon terminal of one neuron and the dendrite of another neuron. It is a key component of the synapse, which is the connection point between two neurons. The synaptic cleft is where neurotransmitters are released from the axon terminal of the presynaptic neuron and received by the dendrite of the postsynaptic neuron. These neurotransmitters help transmit signals between neurons and are essential for communication within the nervous system. The synaptic cleft is filled with extracellular fluid and plays a crucial role in regulating the flow of information between neurons.
