Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which type of cells provide protective cushioning around the neuron cell bodies of the peripheral nervous system?

A	Microglia
B	Satellite cells
C	Astrocytes
D	Oligodendrocytes

Explanation:

Detailed explanation-1: -Satellite glial cells are a type of glial cell that line the exterior surface of neurons in the peripheral nervous system (PNS) . Satellite glial cells (SGCs) also surround neuron cell bodies within ganglia. Satellite cells also act as protective, cushioning cells.

Detailed explanation-2: -They supply nutrients to the surrounding neurons and also have some structural function. Satellite cells also act as protective, cushioning cells. Additionally, they express a variety of receptors that allow for a range of interactions with neuroactive chemicals.

Detailed explanation-3: -The glial cells of the PNS are called Schwann cells and satellite cells. Schwann cells play the same functional role in the PNS as oligodendrocytes do in the CNS, namely providing an insulating cover of myelin over axons and dendrites.
