| Name: | posterior lateral line nerve |
|---|---|
| Synonyms: | caudal lateral line nerve |
| Definition: | Cranial nerve which enters the brain between cranial nerves VIII and IX; contains afferents and sensory efferents to the posterior lateral line ganglion and middle ganglion. Fibers from the posterior lateral line ganglion innervate the occipital dorsal lateral line and trunk lateral lines. |

| Name: | myelination in peripheral nervous system |
|---|---|
| Synonyms: | peripheral nervous system myelination |
| Definition: | The process in which neuronal axons and dendrites become coated with a segmented lipid-rich sheath (myelin) to enable faster and more energetically efficient conduction of electrical impulses. The sheath is formed by the cell membranes of Schwann cells in the peripheral nervous system. Adjacent myelin segments are separated by a non-myelinated stretch of axon called a node of Ranvier. |

| Synonyms: | |
| Definition: | A quality of a process that has a value that is decreased compared to normal or average. |
