Which cells, also called neurilemma cells, are the main glial cells in the PNS and play an essential role in the survival and functions of neurons?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3, i.e. Schwann cells.
Schwann cells, also known as neurilemma cells, are the main glial cells in the PNS. They form the myelin sheath around peripheral neurons and play a crucial role in nerve regeneration, repair, and overall neuron survival.
- Bipolar cells are specialized sensory neurons in the retina.
- Ganglion cells transmit visual information from the retina to the brain.
- Photoreceptor cells detect light in the retina and enable vision.
