This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Head and neck, Subject name: Anatomy
The parasympathetic secretomotor fibres to parotid traverse through the following, except 
Select and explain. 
A. Otic ganglion, B. Tympanic plexus, C. Greater petrosal nerve, D. Aurico temporal nerve
C: Greater petrosal nerve
Answer: C: Greater petrosal nerve 
Explanation: Parasympathetic nerves are secretomotor. They reach the gland through the auriculotemporal nerve. The preganglionic fibres begin in the inferior salivatory nucleus; pass through the glossopharyngeal nerve, its tympanic branch, the tympanic plexus and the lesser petrosal nerve; and relay in the otic ganglion. The postganglionic fibres pass through the auriculotemporal nerve and reach the gland. Ref: BD Chaurasia's HUMAN ANATOMY, Volume 3, 4th edition.
