<prompt> The parasympathetic secretomotor fibres to parotid traverse through the following, exceptOtic ganglionTympanic plexusGreater petrosal nerveAurico temporal nerve  <response>: 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 Chaurasias HUMAN ANATOMY, Volume 3, 4th edition.
