Cochlea

led to her having the sensorineural type of hearing loss (one of the two main types of hearing loss). The two main types of hearing loss are Conductive Hearing Loss (“Damage to eardrum or ossicles”) and Sensorineural Hearing Loss (“Damage to the cochlea, hair cells, or auditory nerve”). On the PowerPoint slide it also talked about what a cochlear implant is (“electronic device that replaces the function of hair cells”) and what it helps with. From the article, Valerie was offered the option to…

this process to occur, the inner ear plays a vital part in sound adaption. The soundwaves we constantly receive through our auditory canal causes a small muscle attached to one of the bones in our eardrums to contract, reducing the vibrations to the cochlea, where vibrations are detected (Myers, Dewall, 256). As long as the stimulus remains unchanged, sensory adaptation is to thank for blocking out unnecessary…

comprises an outer layer of periosteal connective tissue which contains the external bony layer. The middle bony layer is separated from the external bony layer by a thin stratum of almost featureless bone. The inner surface is separated from the cochlea by a narrow endosteal layer. A main feature of the development of the otic capsule is a large number of canals formed in the external and middle layers. In the external layer these are mainly Volkmann’s canal type, which run in all directions.…

The head and neck are part of the body that is very important integrating several systems. A lot of vital activities like eating, drinking, seeing, hearing and breathing are done through the head structures. When the nurse assess those the head and the neck it is s assessing several systems at the same time. The eyes are located in the orbital cavities of the skull is an important part of the head and its function is essential to perform different activities. The ears are one of the structures…

glossopharyngeal, facial, and vagus nerves to the medulla oblongata. 3. Sense of Hearing The ear is associated with the sense of hearing. The inner ear, also known as the labyrinth, has two parts called the osseous and the membranous labyrinths. The cochlea is a part of the labyrinths that functions in hearing. Hearing receptors in the spiral organ are excited by vibrations in the inner ear fluids. The middle ear has auditory ossicles that conduct sound waves to the oval window of the inner ear…

Tinnitus makes people feel distress. Prolonged exposure to loud sounds is the most common cause of tinnitus. 90% of people with tinnitus have some level of hearing loss. The loud noise causes permanent damage to the sound-sensitive cells of the cochlea, a spiral-shaped organ in the inner ear. Carpenters, pilots, rock musicians, street-repair workers, and landscapers are among those whose jobs put them at risk, as are the people who work with chainsaws, guns, or who repeatedly listen to loud…

atresia also affects the middle ear. The middle ear contains three small bones, the ossicles consisting of the incus, stapes and malleus. These tiny bones may be present but will not function properly or can be missing or malformed. In most cases, the cochlea and cochlear nerve are…

direct sound waves down our auditory canal to the tympanic membrane. From there, the membrane sends the vibrations caused by the sound waves to the inner ear, utilizing three tiny bones; malleus, incus, and stapes. The inner ear, also known as the cochlea, is a spiral shaped chamber covered in nerve fibers. The vibrations are transmitted via the auditory nerve to the brain. By combining the impulses sent though both ears the brain is able to determine from which direction a sound came from and…

of the movement and position of the body. Special neurons send messages about the movement of the muscles. Balance and the tracking of body movement is created by the vestibular system, fluid in the ears. The fluid is in sac that connect with the cochlea where the movement sends signals to keep the body up right. The feeling of pain is used to…

SCIENCE ENGINEERING TECHNOLOGY MATHEMATICS By Teanah Bautista and Izak Ford BIOLOGY OF HEARING The hearing is a quite a significant piece of creation used by humans. The complex organization of bones, hair, and cells it captures vibrated sound waves and processes to the brain. With everything happening almost instantly. But it's not as easy as it sounds. The sound is invisible vibrated particles through the air. The moving vibrations cause the air around to also vibrate creating sound waves…
