Question

Quizplus · Accepted Answer

Reuptake refers to the process by which a neurotransmitter that has already been released into the synaptic cleft is taken back into the synaptic knob of the presynaptic neuron or into nearby neuroglia or neurons. This helps to regulate neurotransmitter levels in the synaptic cleft and prevent excessive stimulation of the postsynaptic neuron.
