Synapse

Definition

A synapse is a specialized junction between two neurons or between a neuron and its target cell where communication occurs. It allows for the transmission of electrical or chemical signals from one cell to another.

Analogy

Think of synapses as meeting points for communication between neurons, similar to people conversing at an intersection. Just like how information can be exchanged at this meeting point while traffic flows smoothly along different paths, neurons transmit signals across synapses while maintaining proper functioning of neural circuits.

Presynaptic Neuron: A presynaptic neuron is the sending neuron in a synapse that releases neurotransmitters into the synaptic cleft.

Postsynaptic Neuron: A postsynaptic neuron is the receiving neuron in a synapse that contains receptors for binding with neurotransmitters released by presynaptic neurons.

Synaptic Cleft: The synaptic cleft is a small gap between the presynaptic and postsynaptic neurons where neurotransmitters are released and travel across to bind with receptors.
