Question

Select the correct statement regarding Schwann cells

• A. Surround axon of myelinated nerve fibre
• B. Support muscle fibres
• C. Found in Haversian system of bones
• D. Form basement membrane of epithelium

Answer 1

The correct option is A Surround axon of myelinated nerve fibre

Correct option: A.

Solution: Found in close contact with axons in peripheral nerves, Schwann cells are the main myelinating cells in PNS. Their main function is electrically insulating (myelinating) the neuron, thus increasing axonal conduction velocity which is required for sending proper electrical signals through PNS and to supply nutrients to individual axons. They also play a vital role in regenerating the axon.
