Question

multiple choice 2 points
which cells form myelin sheaths in the spinal cord?
schwann cells
oligodendrocytes
microglia
astrocytes
satellite cells

Explanation:

Identify the anatomical region

The question asks for the cells that form myelin sheaths in the spinal cord. The spinal cord is a component of the Central Nervous System (CNS).

Analyze the function of each cell type

• Schwann cells: Form myelin sheaths in the Peripheral Nervous System (PNS).
• Oligodendrocytes: Form myelin sheaths in the Central Nervous System (CNS).
• Microglia: Act as immune cells/macrophages in the CNS.
• Astrocytes: Provide structural and metabolic support in the CNS.
• Satellite cells: Support neuron cell bodies in PNS ganglia.

Match the region with the correct cell

Since the spinal cord is part of the CNS, the cells responsible for myelination here are oligodendrocytes.

Answer:

• Schwann cells
• Oligodendrocytes (Correct answer)
• Microglia
• Astrocytes
• Satellite cells
