A little later, however, it shows a quite flat, groove-like depression in the middle line of the embryonic shield, directly under the chorda.
A very rudimentary skull is developed at the foremost end of their chorda.
In the middle part of the body this division has already taken place by the construction of the chorda between the dorsal nerve-tube and the ventral canal.
It undergoes a fatty degeneration, and disappears with the chorda dorsalis.
Through it the chorda tympani nerve enters the ympanic cavity.
In a bilateral transection of the chorda tympani in mice, the preference for sodium chloride increases compared to before the transection.
The chorda tympani is part of one of three cranial nerves that are involved in taste.
The chorda tympani appears to exert a particularly strong inhibitory influence on other taste nerves, as well as on pain fibers in the tongue.
