What is the name of the gap between two neurons called?
Answer
Synapse
A synapse is the specialized junction between the axon terminal of one neuron (presynaptic) and the dendrite or soma of another neuron (postsynaptic). This small gap, typically 20-40 nanometers wide, is the site where chemical communication occurs between neurons. When an action potential reaches the axon terminal, vesicles release neurotransmitters that diffuse across the synaptic cleft and bind to receptors on the postsynaptic cell, causing excitation or inhibition. Synapses are the basis of neural communication and learning.
💡 Did you know?
A single neuron can have 1,000-10,000 synapses, and the human brain contains roughly 100 trillion synapses enabling consciousness and thought.
