Glial Cells

Meaning 'glue', in Greek, glia are involved in nearly every function of the brain. They fill all the spaces around neurons, with an approximate width of only 0.02 µm between cells.

Glial cells outnumber neurons 100:1 and are responsible for myelinating neurons.

 

Oligodendrocytes

While Schwann cells myelinate single axons, oligodendrocytes can myelinate up to 100 axons each.
