Reuptake refers to the

A) movement of neurotransmitter molecules across a synaptic gap.
B) release of hormones into the bloodstream.
C) inflow of myelin through an axon membrane.
D) reabsorption of excess neurotransmitter molecules by a sending neuron.

Reuptake

Reuptake is a process by which neurotransmitters are absorbed back into the neuronal presynaptic cell after their release into the synaptic cleft, influencing neurotransmission.

Neurotransmitter Molecules

Chemical substances in the nervous system that transmit signals across synapses from one neuron to another.

Sending Neuron

A neuron that transmits a nerve impulse away from itself towards another neuron, muscle cell, or gland.
