| Name: | pronephric duct |
|---|---|
| Synonyms: | pronephric ducts |
| Definition: | Duct of the embryonic kidney, present bilaterally ventral to the somites and leading to the cloacal chamber. Wingert et al. have suggested that the pronephric duct as described traditionally may consist of subregions which are analogous to portions of the tubule segment of mammalian and other fish nephrons. |

| Name: | motile cilium |
|---|---|
| Synonyms: | microtubule-based flagellum, motile cilia, motile primary cilia, motile primary cilium, motile secondary cilium, nodal cilium |
| Definition: | A cilium which may have a variable arrangement of axonemal microtubules and also contains molecular motors. It may beat with a whip-like pattern that promotes cell motility or transport of fluids and other cells across a cell surface, such as on epithelial cells that line the lumenal ducts of various tissues; or they may display a distinct twirling motion that directs fluid flow asymmetrically across the cellular surface to affect asymmetric body plan organization. Motile cilia can be found in single as well as multiple copies per cell. |

| Name: | has fewer parts of type |
|---|---|
| Synonyms: | decreased number of, has decreased number of, has fewer physical parts of type |
| Definition: | The bearer of this quality has_part < n AND has_part > 0 of the indicated entity type, where n is the normal amount for a comparable organism. Note that the bearer of the quality is the whole, not the part. Formally: If a bearer entity e has fewer parts of type X at time t, then the number of instances x of X at t such that x part_of e is < n, where n is either the normal number for comparable entities, or n is stated explicitly. |

| Name: | outer dynein arm |
|---|---|
| Synonyms: | outer dynein arm complex |
| Definition: | Outer arm structure present on the outer doublet microtubules of ciliary and flagellar axonemes. Outer dynein arms contain 2-3 heavy chains, two or more intermediate chains and a cluster of 4-8 light chains. Inner and outer dynein arms have different functions in the generation of microtubule-based motility. |
