Question

Quizplus · Accepted Answer

Myelin is a fatty substance that wraps around the axon of neurons in the nervous system. Its primary function is to insulate the neurons and speed up the transmission of neural impulses. Glial cells are the cells responsible for producing myelin. Synaptic vesicles are small sacs that store neurotransmitters and dendrites are the branch-like structures that receive signals from other neurons.
