Cerebellar Oligodendrocyte

This drawing of a oligodendrocyte, a type of glial cell, was based upon electron micrograph images of the rat cerebellum.

This drawing shows what the author believes to be the relationship between the oligodendrocyte and myelin. The oligodendrocyte cytoplasm contains numerous RNP particles, an extensive granular endoplasmic reticulum (er), and a prominent Golgi apparatus (G). At the bottom, a thin process (p) is seen arising from the cell body and running along the plasma membrane. Over a large portion of the length of this process, the two membranes are shown as being fused, as apparently occurs in many in- stances. The interperiod line shown between the process and the plasma membrane has been seen on several occasions but is not invariably present. At the lower left, the process spirals around an axon (a) to form a myelin sheath. A larger cell process containing canaliculi (c) is seen at the upper right.
