Question

Glia that provide myelin for neurons in the brain are called ________.

a) Oligodendrocytes
b) Astrocytes
c) Microglia
d) Ependymal cells

Answer 1

Oligodendrocytes are the glial cells that provide myelin for neurons in the central nervous system, aiding in faster signal transmission.

Step-by-step explanation:

The glial cells that provide myelin for neurons in the central nervous system are called oligodendrocytes. Oligodendrocytes are crucial for the formation of myelin sheaths around the axons of neurons, which facilitates faster transmission of electrical signals. Unlike oligodendrocytes, astrocytes provide nutrients and maintain the extracellular environment, microglia scavenge pathogens and dead cells, and ependymal cells produce cerebrospinal fluid. In contrast, in the peripheral nervous system, Schwann cells are responsible for myelination of neurons.
