Question #212
Which of the following nerves does not carry parasympathetic fibres?
Parasympathetic fibres arise in the brainstem and are carried peripherally on cranial nerve fibres to their ganglion. Here the parasympathetic fibres synapse and continue to be carried on fibres of the trigeminal nerve.
- The oculomotor nerve carries fibres to the ciliary ganglion.
- The facial nerve carries fibres to the pterygopalatine and submandibular ganglions.
- The glossopharyngeal nerve carries fibres to the otic ganglion.
The vagus nerve carries parasympathetic fibres from the brainstem to the heart and gastrointestinal tract up to 2/3rds along the transverse colon.
