Synaptic Transmission: The process by which a neurotransmitter is released from a presynaptic neuron, binds to receptors on a postsynaptic cell, and triggers a response.
Receptor: A protein molecule on the surface of a target cell that binds to a specific neurotransmitter, initiating a cellular response.
Reuptake: The process by which a neurotransmitter is removed from the synaptic cleft and transported back into the presynaptic neuron for reuse or degradation.
