Mar 14, 2024 · The oval window is like a doorway between the middle and inner ear. When sound comes in, it makes the oval window vibrate, which starts the process of hearing. Sometimes, there can be a problem with the oval window called oval window anomaly (OWA), where it is not shaped right and may be covered by a thin bony plate.
Middle ear: Anatomy, relating structures and supply | Kenhub
Oct 30, 2023 · The ear is structurally divided into three parts: the external, middle and internal ear. The middle ear is an air-filled pressurized space within the petrous portion of the temporal bone, extending from the tympanic membrane (eardrum) to the lateral wall of the internal ear. It is lined by mucous membrane and communicates with the nasopharynx ...
Auditory pathway: Anatomy, ear structures, transduction - Kenhub
Jul 27, 2023 · Auditory pathway. The external ear/pinna funnels sound waves into a unidirectional wave, and is able to direct it into the auditory canal. This sound then reaches the tympanic membrane, and causes it to vibrate. The louder the sound the bigger the vibration, the lower pitch the sound the slower the vibration.
