d
The taste sensation posterior to the terminal sulcus is supplied by the vagus nerve
QuestionChoice
The hypoglossal nerve provides the motor innervation to all tongue muscles (apart from the palatoglossus, which is innervated by the vagus nerve). If the hypoglossal nerve on one side becomes damaged, the tongue deviates laterally towards the side of injury, due to the unopposed action of the genioglossus muscle on the intact side.

a
Damage to the hypoglossal nerve results in the tongue deviating laterally towards the side of the injury
QuestionChoice
The chorda tympani branch of the facial nerve supplies taste sensation to the anterior 2/3 of the tongue. The touch, temperature and pain sensation to this area is supplied by the lingual nerve, a branch of the mandibular trigeminal nerve.

e
The chorda tympani branch of the facial nerve supplies touch, temperature and pain sensation to anterior 2/3 of the tongue
QuestionChoice
The genioglossus and styloglossus muscles are innervated by the hypoglossal nerve whereas the palatoglossus is innervated by the vagus nerve.

c
The genioglossus, styloglossus and palatoglossus muscles are all innervated by the hypoglossal nerve
QuestionChoice
Filiform papillae are touch-detecting papillae located on the anterior 2/3 of the tongue, arranged in rows parallel to the terminal sulcus. Fungiform papillae are club-shaped projections found on the tip and sides of the tongue, which detect taste.

b
Filiform and fungiform papillae are found across the whole surface of the tongue
