Neuron Oligodendrocyte, snaps activity in brain.
A glial cell similar to an astrocyte but with fewer protuberances, concerned with the production of myelin in the central nervous system.
There are also supporting tissues in the nervous system, known collectively as glia; for example, Schwann cells surround the axons of peripheral neurons, and oligodendrocytes and astrocytes ensheath the axons of central neurons.
