which type of neuroglia form(s) the myelin sheath around nerves? select all that apply. a schwann cells b oligodendrocytes c ependymal cells d astrocytes

Answer

Brief Explanations:

Schwann cells form the myelin sheath around axons in the peripheral nervous system, and oligodendrocytes form the myelin sheath around axons in the central nervous system. Ependymal cells line the ventricles of the brain and central canal of the spinal cord, and astrocytes have functions like providing support and maintaining the blood - brain barrier but do not form myelin sheaths.

Answer:

A. Schwann cells, B. Oligodendrocytes
