Schwann cell

 (shwän, shvän)
n.
Any of the cells that surround the axons of the peripheral nerves, forming the myelin sheath of myelinated nerve fibers and providing support for nonmyelinated nerve fibers. Also called neurilemma.

[After Theodor Schwann.]

Schwann′ cell`


n.
a cell of the peripheral nervous system that wraps around a nerve fiber, jelly-roll fashion, forming the myelin sheath.
[1930–35; after T. Schwann, who first described it]

Melnick, PhD said: "The findings of brain tumors (gliomas) and malignant schwann cell tumors of the heart in the NTP study, as well as DNA damage in brain cells, present a major public health concern because these occurred in the same types of cells that have been reported to develop into tumors in epidemiological studies of adult cell phone users.
