Final answer:
Satellite cells are the glial cells that support neurons in the Peripheral Nervous System by providing nutrients and structural support, similar to the role of astrocytes in the CNS. option a.
Step-by-step explanation:
Among the choices provided to support neurons in the Peripheral Nervous System (PNS), the correct answer is a. Satellite cells. Satellite cells are glial cells that surround the cell bodies of neurons within the PNS, serving a support role similar to astrocytes in the Central Nervous System (CNS). However, unlike astrocytes, they do not contribute to establishing the Blood-Brain Barrier (BBB). Astrocytes are star-shaped glial cells that maintain the extracellular environment and provide structural support in the CNS, whereas oligodendrocytes form the myelin sheath around axons also within the CNS. Thus, for the question regarding PNS support neurons, only satellite cells are relevant.
