How Does Neurilemma Play a Role in Regeneration

Neurilemma serves a protective function for peripheral nerve fibers. Damaged nerve fibers may regenerate if the cell body is not damaged and the neurilemma remains intact. The neurilemma forms a regeneration tube through which the growing axon re-establishes its original connection.

What role does the neurilemma play in the nervous system?

The unmyelinated regions between the myelin segments are called the nodes of Ranvier. In the peripheral nervous system, the myelin is produced by Schwann cells. … This covering is the neurilemma, which plays an important role in the regeneration of nerve fibers.

What is the difference between neurilemma and myelin sheath?

The main difference between neurilemma and myelin sheath is that neurilemma is the plasma membrane layer of the Schwann cells whereas myelin sheath is the fatty acid layer that encloses the nerve fiber. … Both oligodendrocytes and Schwann cells are supporting cells in the nervous system.
