Neurilemma

Neurolemma (also neurilemma and sheath of Schwann) is the outermost layer of nerve fibers in the peripheral nervous system. It is a nucleated cytoplasmic layer of schwann cells that surrounds the myelin sheath of axons.

unlike the axon and the myelin sheath, the neurolemma does not degenerate after a nerve has been cut or crushed; the hollow tube formed by the neurolemma is instrumental in regenerating the nerve Fiber (see wallerian degeneration

Difference between Schwann's Cells, myelin sheath and...

As far as I know, you are perfectly right. Schwann cells produce myelin sheath. Myelin sheath surrounds the axon. Neurilemma wraps the myelin sheath. Here, this may help: http://www.waybuilder.net/sweethaven/MedTech/Neurology/fig0103.jpg

Difference between Schwann's Cells, myelin sheath and...

Hi, What is the difference between Schwann's Cells, myelin sheath and neurilemma? Does Schwann's cells produce the myelin sheath, and the myelin sheath surrounds the axon, kind of, but what does the neurilemma do? Does it wrap the myelin sheath? Thanks! :mrgreen:

TWO QUESTIONS??

... "The nerve fiber is composed of an axon, a neurite and often its covering. The axons of the peripheral nervous system are covered by a sheath (neurilemma) composed of Schwann cells. The neurilemma is comparable to certain neuroglia of the central nervous system. Large diameter peripheral nerves ...
