    The foramen tympanicum, or also known as the foramen of Huschke, is an anatomical variation of the tympanic part of the temporal bone in humans resulting from a defect in normal ossification during the first five years of life. The structure was found in 4.6% [1] to as high as 23% of the population. [citation needed]

    en.wikipedia.org/wiki/Facial_nerve

    The main function of the facial nerve is motor control of all the muscles of facial expression. It also innervates the posterior belly of the digastric muscle, the stylohyoid muscle, and the stapedius muscle of the middle ear. These skeletal muscles are developed from the second pharyngeal arch.

    The auricular branch of the vagus nerve is often termed the Alderman's nerve ("a reference to the old Aldermen of the City of London and their practice of using rosewater bowls at ceremonial banquets, where attendees were encouraged to place a napkin moistened with rosewater behind their ears in the belief that this would aid digestion") or Arnold's nerve (an eponym for Friedrich Arnold).

    en.wikipedia.org/wiki/Tympanic_nerve

    The tympanic nerve (Jacobson's nerve) is a branch of the glossopharyngeal nerve passing through the petrous part of the temporal bone to reach the middle ear. It provides sensory innervation for the middle ear, the Eustachian tube, the parotid gland, and mastoid cells. It also carries parasympathetic fibers destined for the parotid gland.

    The central portion of the tympanic part is thin, as it gives rise to the bony inner two-thirds of the ear canal, and in 5 - 20% of skulls the lower surface is perforated by a hole, the foramen of Huschke [1] that opens onto the temporomandibular joint due to incomplete fusion of the anterior and posterior prominences during development.

  8. Posterior auricular nerve - Wikipedia

    en.wikipedia.org/wiki/Posterior_auricular_nerve

    The posterior auricular nerve arises from the facial nerve (CN VII). [1] It is the first branch outside of the skull. [2] This origin is close to the stylomastoid foramen.It runs upward in front of the mastoid process.

    The cochlear and vestibular branches of cranial nerve VIII separate according to this schema and terminate in the inner ear. The facial nerve continues traveling through the facial canal, eventually exiting the skull at the stylomastoid foramen. A common mnemonic to remember the anterior quadrants of the inner ear is: "seven up, coke down ...
