Neurotransmitters

Chemical messengers that transmit signals across a chemical synapse, from one neuron (nerve cell) to another target neuron, muscle cell, or gland cell.

Myelinization

The process of forming a myelin sheath around the axons of neurons, which increases the speed at which electrical impulses propagate along the nerve cells.
