The lesser petrosal nerve is the visceral motor component of the glossopharyngeal nerve (CN IX), carrying parasympathetic fibres from the tympanic plexus to the parotid gland.
After arising in the tympanic plexus, lesser petrosal nerve passes from the temporal bone into the middle cranial fossa via hiatus for lesser petrosal nerve. It travels across the floor of the middle cranial fossa, then exits the skull via foramen ovale to reach the infratemporal fossa. The fibres synapse in the otic ganglion, and post-ganglionic fibres then travel briefly with the auriculotemporal nerve (a branch of V3) before entering the body of the parotid gland.

Famous quotes containing the words lesser and/or nerve:
“So hills and valleys into singing break;
And though poor stones have neither speech nor tongue,
While active winds and streams both run and speak,
Yet stones are deep in admiration.
Thus praise and prayer here beneath the Sun
Make lesser mornings when the great are done.”
—Henry Vaughan (1622–1695)
“The American people is out to get the kaiser. We are bending every nerve and every energy towards that end; anybody who gets in the way of the great machine the energy and devotion of a hundred million patriots is building towards the stainless purpose of saving civilization from the Huns will be mashed like a fly. I’m surprised that a collegebred man like you hasn’t more sense. Don’t monkey with the buzzsaw.”
—John Dos Passos (1896–1970)
