Reuptake

The process by which neurotransmitters are taken back into the synaptic vesicles of a neuron after they have been released into a synaptic cleft.

Chemical Synapses

Junctions through which neurons signal to each other or to non-neuronal cells, where neurotransmitters are released and bind to receptors.

Electrical Synapses

A type of synapse that allows direct transmission of electrical signals between neurons, facilitating faster communication than chemical synapses.

Mammalian Nervous System

The integral network in mammals that coordinates voluntary and involuntary actions by transmitting signals between different body parts and the brain.
