| Synonyms: | midbody lateral line, midtrunk line, pll |
| Definition: | One of eight distinct lateral lines in the 4-day larva. The posterior lateral line runs along the horizontal myoseptum from the otic vessicle to the caudal fin. Lateral lines form a sensory system on the surface of the fish, consisting of small sensory patches (neuromasts) distributed in discrete lines over the body surface. The lateral line system is stimulated by local water displacements and vibrations, and detects propulsion of the fish through the water, as well as facilitating shoaling, prey capture, and predator and obstacle avoidance. (See Anatomical Atlas entry for lateral line by T. Whitfield.) |

| Name: | glial cell (sensu Vertebrata) |
|---|---|
| Synonyms: | glial cells (sensu Vertebrata) |
| Definition: | A non-neuronal cells of the nervous system. They not only provide physical support, but also respond to injury, regulate the ionic and chemical composition of the extracellular milieu. Form the myelin insulation of nervous pathways, guide neuronal migration during development, and exchange metabolites with neurons. Neuroglia have high-affinity transmitter uptake systems, voltage-dependent and transmitter-gated ion channels, and can release transmitters, but their role in signaling (as in many other functions) is unclear. |
