Question

What are Schwann cells and their function?

Answer 1

Answer:

Schwann cell is A type of glial cell of the peripheral nervous system that helps separate and insulate nerve cells.

it's function are:

1.Schwann cells serve as the myelinating cell of the PNS

2.it support cells of peripheral neurons.

3.it forms a myelin sheath by wrapping its plasma membrane concentrically around the inner axon.

4.it helps to separate and insulate nerve cells.

Answer 2

schwann cells serve as the myelinating cell of the PNS and support cells of peripheral neurons . A schwann cell forms a myelin sheath bt wrapping it's plasma membrane concentrically around the inner axon .

STRUCTURE

schwann cells are variety of glial cells that keep peripheral neuron fibres ( both myelinating and unmyelinating ) alive .In myelinated axons , schwann cells form the myelin sheath . The sheath is not continuous

FUNCTION

one of the most important function of the schwann cells is to myelinate the axons of the PNS . myelin whuch is a fatty layer thst insulates the axon , helps to increase the saltatory condunction of neuron . A myelinating schwann cells wraps around a single axon.

hope this ans help you .
