Nerve of the Eardrum

Nerve of the tympanic membrane

The tympanic nerve (lat. Nervus membrana tympanica) is a paired nerve bundle consisting of an internal and external section. It passes through the cavity of the middle ear, where it performs the function of controlling the position of the tympanum.

The ear drum is a thin, flexible membrane that sits inside the middle ear. It covers the inner ear - the part of the hearing aid responsible for the perception of sound. The softening and retraction of the membrane is called tympany.

- The main functions of drumming are:

1. Air retention: It seals the middle ear and protects it from external influences. 2. Position control: Thanks to the nerve endings, the tympanum controls the position of the middle ear relative to the bones of the skull. This helps maintain proper hearing balance between the two ears, which is especially important for people with facial asymmetry or the absence of one ear. 3. Sound duct: When different notes are played, vibrations from the ear drum are transmitted to the fluid in the middle ear. This allows you to feel the volume and timbre of the sound. 4. Regulation

Nerve of the tympanic membrane - (n. membran ae tympa n i) - is one of the peripheral nerves of the external ear. The term “nerves of the ear” refers mainly to the cranial nerves (VI, VII) innervating the external auditory canal (they can be considered the abducens of the cochlear apparatus) and the inner ear and brain. For the most part, the eardrum is supplied by the inferior and middle auricular nerves and the posterior auricular branches. The superior auricular nerve does not touch the membrane and works independently.

The posterior auricular-auditory nerve, the posterior auricular nerve, or Thomson's nerve, is a branch of the superior ganglion that arises from the mandibular (inferior orbital) nerve in the brain stem. The posterior auricular branches form the internal auditory (esophageal) nerve, from which the tympanic and round window arteries arise
