| The central canal and surrounding gray matter appear as though pushed dorsally by the decussating bundles of axons. |
| The axon counts were extrapolated by using the area algorithm to estimate the total number of axons for each nerve. |
| The oligodendrocyte does not form a neurilemma because its cell body does not wrap around any axons. |
| They receive the axons of the 15 million Purkinje cells, the largest cells in the cortex. |
| Although fish axons are capable of regeneration, they are nevertheless repelled by mammalian CNS myelin and oligodendrocytes. |
| Myelin acts as a multilamellar insulator around brain axons and is expressed by oligodendrocytes in the central nervous system. |
