Question

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

Explanation:

• Schwann cells form myelin sheaths in the peripheral nervous system.
• Astrocytes have functions like providing structural support and regulating the extracellular environment in the central nervous system but not forming myelin sheaths.
• Satellite cells are related to muscle repair and are not involved in forming myelin sheaths in the spinal cord.
• Microglia are the immune cells of the central nervous system.
• Oligodendrocytes are the cells that form myelin sheaths in the central nervous system (including the spinal cord).

Answer:

Oligodendrocytes
