QuestionChoice
Incorrect. The submandibular ganglion is is a cranial parasympathetic ganglion located in the submandibular fossa on the medial aspect of the mandibular body. Preganglionic parasympathetic fibres are carried by the chorda tympani (branch of facial nerve, CN VII), which synapse within the ganglion. Postganglionic parasympathetic fibres are then carried by the lingual nerve (branch of mandibular nerve, CN Vc) to supply the submandibular and sublingual glands, as taste to the anterior two thirds of the tongue.

Submandibular ganglion
QuestionChoice
Incorrect. The otic ganglion is a cranial parasympathetic ganglion located in the infratemporal fossa inferior to the foramen ovale. Preganglionic parasympathetic fibres are carried by the lesser petrosal nerve (branch of glossopharyngeal nerve, CN IX), which synapse within the ganglion. Postganglionic parasympathetic fibres are then carried by the auriculotemporal nerve (branch of mandibular nerve, CN Vc) to supply the parotid gland.

Otic ganglion
QuestionChoice
Correct. The trigeminal ganglion is a sensory ganglion located at the apex of the petrous temporal bone, in what is called the trigeminal impression. It contains the cell bodies of sensory neurones carried by the trigeminal nerve (CN V), and no synapses. The ophthalmic, maxillary, and mandibular division of CN V arise from this ganglion.

QuestionChoice
Incorrect. The ciliary ganglion is a cranial parasympathetic ganglion located inferior to the eye. Preganglionic parasympathetic fibres are carried by the oculomotor nerve (CN III), which synapse within the ganglion. Postganglionic parasympathetic fibres are then carried by the short ciliary branch of the nasociliary nerve (branch of ophthalmic nerve, CN Va) to supply the sphincter pupillae and ciliary muscles.

QuestionChoice
Incorrect. The pterygopalatine ganglion is a cranial parasympathetic ganglion located in the pterygopalatine fossa between the pterygoid plates of the sphenoid bone and the palatine bone. Preganglionic parasympathetic fibres are carried by the greater petrosal nerve (branch of facial nerve, CN VII), which synapse within the ganglion. Postganglionic parasympathetic fibres are then carried by several branches of the maxillary nerve (CN Vb) to supply the lacrimal, nasal, palatine, and pharyngeal glands (also known as the hayfever glands).
