Multiple Myelin Sheaths in Single Schwann Cells

Abstract

DURING an electron microscopic investigation of the normal structure of the trigeminal ganglion in the rat, particular attention was given to various stages of myelin sheath formation1. Frequently it was observed that two or more myelinated axons were enclosed within the cytoplasm of a single Schwann cell. Such a finding was difficult to correlate with the widely accepted theories of myelin formation from the Schwann cell surface2, and the possibility was considered that this variation in myelin contour was an indication of axon branching.
