Question

Quizplus · Accepted Answer

The myelin sheath in the central nervous system is made up of glial cells, specifically oligodendrocytes. These cells wrap around the axons of neurons, creating the fatty myelin sheath which helps to insulate and speed up neural impulses. Neurotransmitters and GABA are involved in communication between neurons, while dendrites are extensions of neurons that receive signals from other neurons.
