A benign peripheral nerve sheath tumor is a schwannoma or neurofibroma.
The medical terminology combining form meaning sheath is "thec/o".
Athecal
Neurilemmomas are benign, encapsulated tumors of the nerve sheath.
Ganglion cyst
axon of a neuron in the peripheral nervous system.Schwann cells form a myelin sheath around the Axon.
An insulating layer that surrounds the axon is a myelin sheath.
You can have benign tumors of myelin sheath cells, like astrocytoma. Nerve cells do not divide and so you do not get tumors of nerve cells. Also destruction of the myelin sheath is the cause of MS (multiple sclerosis).
Myelin is a fatty sheath around axons found in the peripheral nervous system.
fatty sheath is a layer of proteins surrounding the axons in the perisheral nervous system
The myelin sheath is an extruded plasma membrane wrapped in a spiral fashion around a nerve axon. The myelin membranes are part of the Schwann cells of the peripheral nervous system.
The protective covering over some nerve cells is called the myelin sheath.
The glial cells: oligodendrocytes for central nervous system and schwann cells for peripheral nervous system.
