Question

Quizplus · Accepted Answer

Schwann cells are a type of glial cell found in the peripheral nervous system that provide myelin for peripheral nerve cells. They wrap around a single segment of axon membrane to form a myelin sheath. A single Schwann cell myelinates only one segment of axon membrane, but many Schwann cells can work together to myelinate a single axon.
