Hairy ear (auricular hypertrichosis) is hair growing on or in your outer ear, the part of your ear you can see. Ear hair doesn’t affect your hearing. But having noticeable amounts of ear hair may make you feel self-conscious about your appearance. There are …

In mammals, the auditory hair cells are located within the spiral organ of Corti on the thin basilar membrane in the cochlea of the inner ear. They derive their name from the tufts of stereocilia called hair bundles that protrude from the apical surface of …

2023年9月12日 · Terminal ear hair works together with your body’s natural ear wax to form a protective barrier. Just like nose hair, it helps to prevent germs, bacteria, and debris from getting inside your...

2023年7月7日 · Prolonged exposure to loud noise harms hair cells in a variety of ways, and one of those is by damaging the cores of the “hairs” themselves. These hair-like structures are known as stereocilia, and Shin’s new research shows a process they use to repair themselves.

Ear hair is the terminal hair arising from folliculary cartilage inside the external auditory meatus in humans. [1] In its broader sense, ear hair may also include the fine vellus hair covering much of the ear, particularly at the prominent parts of the anterior ear, or even the abnormal hair growth as seen in hypertrichosis and hirsutism .

2023年4月19日 · Scientists are examining different gene therapy and surgical methods, including an approach previously honed at Mass Eye and Ear, in which a different viral vector called an adeno-associated virus (AAV) was able to precisely and safely deliver gene therapy to the inner ear through a novel surgery.

2023年7月10日 · "Hair cells" found in the inner ear, are important both for our ability to hear and our sense of balance. They are known as hair cells because the cells are covered in hair-like structures that...

The cochlear hair cells in humans consist of one row of inner hair cells and three rows of outer hair cells (see Figure 13.4). The inner hair cells are the actual sensory receptors, and 95% of the fibers of the auditory nerve that project to the brain arise from this subpopulation.

The OAE test checks how the sensory hair cells within your inner ear are working. The ABR test checks how well your main hearing nerve is working. Vestibular tests : A vestibular test battery includes several tests that check how well the vestibular (balance) part of …

Several studies that had examined the inner ears of deaf people shortly after they died demonstrated that outer hair cells were required for hearing. It was clear that the inner hair cells served to transmit information to the brain but the role of the outer hair cells remained a mystery.
