WebA tympanic membrane retraction is a condition where the tympanic membrane, or eardrum, gets pulled toward the middle of your ear. Here's what you need to know about the … WebIn order for a sound to be transmitted to the central nervous system, the energy of the sound undergoes three transformations.First, the air vibrations are converted to vibrations of the tympanic membrane and ossicles of the middle ear. These in turn become vibrations in the fluid within the cochlea. Finally, the fluid vibrations set up traveling waves along the … prime rate as today

The other structures are called the semicircular canals, which are responsible for balance, while the cochlea is involved in hearing. Behind the eardrum are the ossicles, tiny bones that play a vital role in hearing. At the bottom of the stapes sits the oval window. Web5 de mar. de 2024 · A new mechanism that contributes to control of hearing sensitivity is described here. We show that an accessory structure in the hearing organ, the tectorial membrane, affects the function of inner ear sensory cells by storing calcium ions.
