The parasympathetic secretomotor fibres to parotid traverse through the following, except
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.
