Question
In the central nervous system, myelin is formed by cells called oligodendrocytes. In the peripheral nervous system, myelin is formed by cells called Schwann cells.
Solution
In the central nervous system (CNS), myelin is formed by oligodendrocytes. These specialized glial cells wrap around the axons of neurons, creating the myelin sheath that insulates and facilitates the efficient transmission of electrical signals.
In the peripheral nervous system (PNS), myelin is formed by Schwann cells. Similar to oligodendrocytes, Schwann cells encase the axons of peripheral neurons with myelin, allowing for swift conduction of action potentials and aiding in the regeneration of damaged nerves.
Thus, the complete answer is:
- In the central nervous system, myelin is formed by cells called oligodendrocytes.
- In the peripheral nervous system, myelin is formed by cells called Schwann cells.
