Correct Answer � C Explanation |
 |
C) Nucleus Solitarius (Solitary Nucleus)
-
The facial nerve (CN VII)carries taste fibers (special visceral afferent)from the anterior two-thirds of the tongue via the chorda tympani.
-
These taste fibers terminate in the nucleus of the solitary tract (nucleus solitarius)in the medulla.
-
The upper (rostral) part of the nucleus solitarius specifically receives taste sensation from:
-
CN VII (anterior 2/3 tongue)
-
CN IX (posterior 1/3 tongue)
-
CN X (epiglottis)
