| Name: | dorsal longitudinal anastomotic vessel |
|---|---|
| Synonyms: | DLAV |
| Definition: | Paired trunk vessels that run medially along the dorsal-most portion of the trunk and post-vent region. The DLAVs are formed by the longitudinal anastomoses of the intersegmental vessels to form a right and left pair of dorsal longitudinal anastomotic vessels. These paired vessels remodel to form a single plexiform vessel beginning at 3dpf continuing until after 7dpf. The basilar artery connects to the DLAVs at the caudal end of the medulla oblongata. In the early embryo (2.5-3.5 dpf) the primitive hindbrain channels also connect to the DLAV. |

| Name: | sprouting angiogenesis |
|---|---|
| Synonyms: | |
| Definition: | The extension of new blood vessels from existing vessels into avascular tissues, this process includes the specialization of endothelial cells into leading tip and stalk cells, proliferation and migration of the endothelial cells and cell adhesion resulting in angiogenic sprout fusion or lumen formation. |
