b
The facial nerve gives parasympathetic supply to the parotid gland
QuestionChoice
The facial nerve gives motor supply to the facial muscles such as the buccinator. However, the motor supply to the extrinsic tongue muscles is via the hypoglossal and vagus nerves.

c
The facial nerve gives the motor supply to facial and extrinsic tongue muscles such as the buccinator, mylohyoid and palatoglossus
QuestionChoice
The facial nerve innervates the efferent limb of the corneal reflex via the greater petrosal nerve, as this innervates the orbicularis oculi muscle. The afferent limb of the corneal reflex is via the ophthalmic division of the trigeminal nerve.

d
The facial nerve innervates the afferent limb of the corneal reflex via the greater petrosal nerve
QuestionChoice
The terminal sulcus divides the tongue into portions: the anterior 2/3 and posterior 1/3. The taste sensation to the anterior 2/3 is supplied by the chorda tympani branch of the facial nerve.

a
Taste fibres to the anterior 2/3 of the tongue are supplied by the facial nerve
QuestionChoice
The chorda tympani travels with the mandibular trigeminal branch to supply taste sensation to the tongue. The greater petrosal nerve travels with the ophthalmic trigeminal nerve to supply the lacrimal gland.
