Summary Summary. Schwannomatosis is a rare form of neurofibromatosis that is primarily characterized by multiple schwannomas (benign tumors of the nervous system) in the absence of bilateral (affecting both sides) vestibular schwannomas.
Schwann cell. Definition. noun, plural: Schwann cells. A glial cell that wraps around the nerve fiber in the peripheral nervous system, and forms the myelin sheaths of peripheral axons. Supplement. Schwann cells form a fatty material called myelin to insulate the axons in the peripheral nervous system. This method decreases membrane capacitance in the axon, thus, allowing saltatory conduction. Non-myelinating Schwann cells are involved in maintenance of axons and are crucial for neuronal survival.
