QuestionChoice
Incorrect. The arrow points to the oculomotor nerve (CN III), exiting the brain at the level of the colliculi and Edinger-Westphal nucleus in the midbrain. The trigeminal ganglion is a sensory ganglion located at the apex of the petrous temporal bone. It contains the cell bodies of sensory neurones carried by the trigeminal nerve (CN V), and importantly, no synapses.

QuestionChoice
Incorrect. The arrow points to the oculomotor nerve (CN III), exiting the brain at the level of the colliculi and Edinger-Westphal nucleus in the midbrain. The otic ganglion is a parasympathetic ganglion that receives preganglionic parasympathetic fibres, which synapse in the ganglion, from the lesser petrosal nerve (a branch of the glossopharyngeal nerve, CN IX).

QuestionChoice
Correct. The arrow points to the oculomotor nerve (CN III), exiting the brain at the level of the colliculi and Edinger-Westphal nucleus in the midbrain. The ciliary ganglion is a parasympathetic ganglion that receives preganglionic parasympathetic fibres, which synapse in the ganglion, from the inferior division of CN III.

QuestionChoice
Incorrect. The arrow points to the oculomotor nerve (CN III), exiting the brain at the level of the colliculi and Edinger-Westphal nucleus in the midbrain. The geniculate ganglion is a sensory ganglion located in the petrous temporal bone. It contains the cell bodies of viscerosensory neurones carried by the facial nerve (CN VII), and importantly, no synapses.
