Show Answer
Correct Answer – D
The sensory innervation of the tongue reflects its embryological development.
The nerve of general sensation to the presacral part is the lingual nerve, which also carries taste sensation derived from the chorda tympani branch of the facial nerve.
The nerve supplying both general and taste sensation to the postsulcal part is the glossopharyngeal nerve.
An additional area in the region of the vallecula is supplied by the internal laryngeal branch of the vagus nerve.
