QuestionSBA
QuestionChoice
Incorrect. The arrow points to the parotid gland, which receives postganglionic parasympathetic secretomotor innervation via the auriculotemporal nerve (from the mandibular nerve, CN Vc) from the otic ganglion. The pterygopalatine ganglion is the origin of postganglionic parasympathetic secretomotor innervation to the lacrimal gland, nasal and palatine mucosa.

d
Pterygopalatine ganglion
QuestionChoice
Correct. The arrow points to the parotid gland. Preganglionic parasympathetic fibres travel in the lesser petrosal nerve (from the glossopharyngeal nerve, CN IX) and synapse at the otic ganglion to give postganglionic parasympathetic secretomotor fibres that run with the auriculotemporal nerve (from the mandibular nerve, CN Vc) to supply the parotid gland.

a
Otic ganglion
QuestionChoice
Incorrect. The arrow points to the parotid gland, which receives postganglionic parasympathetic secretomotor innervation via the auriculotemporal nerve (from the mandibular nerve, CN Vc) from the otic ganglion. The trigeminal ganglion contains sensory cell bodies of the trigeminal nerve (CN V), not synapses.

Trigeminal ganglion
QuestionChoice
Incorrect. The arrow points to the parotid gland, which receives postganglionic parasympathetic secretomotor innervation via the auriculotemporal nerve (from the mandibular nerve, CN Vc) from the otic ganglion. The submandibular ganglion is the origin of postganglionic parasympathetic secretomotor innervation to the submandibular and sublingual glands.

QuestionChoice
Incorrect. The arrow points to the parotid gland, which receives postganglionic parasympathetic secretomotor innervation via the auriculotemporal nerve (from the mandibular nerve, CN Vc) from the otic ganglion. The ciliary ganglion is the origin of postganglionic parasympathetic innervation to the sphincter pupillae and ciliary muscles.
