| The oligodendrocyte does not form a neurilemma because its cell body does not wrap around any axons. |
| The central canal and surrounding gray matter appear as though pushed dorsally by the decussating bundles of axons. |
| The axons from the fifth cervical nerve supply the first digitation and the sixth and seventh supply the remainder of the muscle mass. |
| The neurologic symptoms are a result of destruction of myelin, though axons may also be affected. |
| Although fish axons are capable of regeneration, they are nevertheless repelled by mammalian CNS myelin and oligodendrocytes. |
| Neurons grow cordlike extensions called axons and dendrites, collectively called neurites, that attach to other neurons. |
