Why unmyelinated nerve fibres are enclosed by Schwaan cells?

Answers

Answered by swetha275

Non-myelinated nerve fibres of the peripheral nervous system are enclosed within continuous chains of Schwann cells. However, in comparison to myelinated fibres, there are no nodes of Ranvier in non-myelinated fibres and there may be as many as nine nerve fibres enveloped within the folds of the Schwann cells in the chain

HOPE IT HELPS YOU

ziafat111: but if they have continuous myelin sheath then why they are called as non -myelinated

swetha275: they have continuous schwaan cells no myelin sheath

ziafat111: ok..but myelin sheath is made up of schwaan cells

swetha275: The myelin sheath is made of a material called myelin, which is produced by special cells known as Schwann cells.
