Question:
Neurilemma around axon of a neuron is formed by:
Neurilemma around axon of a neuron is formed by:
Show Hint
Neurilemma = Schwann cell-derived sheath in PNS. Oligodendrocytes lack neurilemma in CNS.
Updated On: Jun 2, 2025
- Ependymal cells
- Microglial cells
- Schwann cells
- Oligodendrocytes
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
- Schwann cells: Form myelin sheath and neurilemma in peripheral nervous system.
- Oligodendrocytes: Myelinate neurons in CNS — do not form neurilemma.
- Ependymal cells: Line brain ventricles, not involved in sheath.
- Microglial cells: Immune cells in CNS.
- Oligodendrocytes: Myelinate neurons in CNS — do not form neurilemma.
- Ependymal cells: Line brain ventricles, not involved in sheath.
- Microglial cells: Immune cells in CNS.
