stomochord Zool.|ˈstɒməʊkɔːd|
[f. Gr. στόµα mouth + χορδή chord n.1, after notochord.]
Name proposed by Willey for the so-called ‘notochord’ of Enteropneusta: see quots. Hence stomoˈchordal a., pertaining to or having a stomochord.
1899Willey in Q. Jrnl. Microscop. Sci. XLII. 234 MM. Delage and Hérouard retain the designation notochord applied by Bateson to the diverticulum from the throat which projects into the proboscis, where it acquires a rigid consistency and sustaining properties. I prefer to call this structure by a non-committal name, and propose the term stomochord. 1902G. H. Fowler in Encycl. Brit. XXIX. 251/1 The stomochord is a forward dorsal diverticulum of the gut in the collar region, which pushes before it the wall of the præ-oral body cavity or protocœle. |
