| Anatomical terminology[edit on Wikidata] |
The cephalic flexure is the first flexure, or bend, of the embryonic brain; it appears in the region of the mid-brain.
By means of it the fore-brain is bent in a ventral direction around the anterior end of the notochord and fore-gut, with the result that the floor of the fore-brain comes to lie almost parallel with that of the hind-brain.
This flexure causes the mid-brain to become, for a time, the most prominent part of the brain, since its dorsal surface corresponds with the convexity of the curve.
