Inner ear

The ear is sectioned off into three parts, the outer, the middle, and the inner ear. Each section serves its own function to the hearing of an individual. The external portion of the ear includes the auricle, the auditory canal, and the eardrum outer layer. The auricle is the cartilage that is covered by skin on opposite sides of the head, the auditory canal, more commonly called the ear canal, is the tunnel in which sound waves travel down, and the ear drum, also known as the tympanic membrane.

hearing loss and other substantial symptoms. One disorder that shows how one malformation can cause overall hearing deficits is Otosclerosis. Otosclerosis is a disorder in which there is a malfunction during the fusion of bones in the middle ear and inner ear, which in turn causes the ossicles or surrounding bones not to vibrate in a manner that is conducive for proper hearing. The Etiology is unclear but scientist does have speculations of the possible onsets of Otosclerosis. Scientist have made

Catherine Pastor, Essay 2, Castillo 1-I, December 3rd 2014 The inner ear is made up of a complex interconnectedness of small bones. The incus, stapes and malleus are the three small bones of which the inner ear is composed. The function of this evolutionary development is to allow for hearing and furthermore acts to assist in balance. These three bones are collectively referred to as ossicles. The efficiency of these features allow for an acute sense of hearing in vertebrates. The physical shape

Meniere 's disease is a disease of the inner ear comprised of three main symptoms: tinnitus, hearing loss and occasional, long lasting vertigo. Any patient may have some or all of these, to varying degrees, between one or both ears. Tinnitus or aural pressure is especially prevalent before an episode of vertigo. These vertigo attacks can last anywhere from 20 minutes up to a full day per attack and are often associated with vomiting and nausea [X1]. It is thought that endolymphatic hydrops is the

peripheral vestibular system, but can be abnormal with concomitant abnormalities such as atresia, stenosis, fluid in the middle ear, thickened temporal bone, lack of cooperation, and so forth. Thus, rotary chair testing can be use to accurately assess the functioning of the VOR and peripheral vestibular functioning because its validity is not affected by existing middle and inner ear structural abnormalities/disease (Phillips, 2013). Rotary chair testing is used to diagnose peripheral vestibular lesions

afraid in a safe environment such as inside a skyscraper. Acrophobia is treated with graded exposure therapy. (Horton, 2011) Fear of heights seems to have a simple physiological explanation, and there is a solution to it: Learn to rely more on your ears for balancing. Fear of heights In this essay I try to analyze my fear of height through

to start spinning out of nowhere. This is caused by an inner ear condition. If you move so fast a certain way it will cause your body to be off balance which will cause you to feel a spinning sensation. This is caused by the calcium particles in your ears to block the canals. My dad has vertigo and there are sometimes when he has to go to the doctor to get his head shaken. The reason for this is to help get the calcium particles in your ears back on balance. When he first noticed something was wrong

deflection of hair cells within the endolymph sends a signal to the brain relaying the motion. The semicircular canals rely on the change in position to signal the motion, and thus cannot report constant velocity rotations. Otolith organs within the inner ear measure the direction of acceleration through the movement of otoconia

Sickness marked with the nausea, dizziness, vomiting or even while on the go. This disease is a disorder that occurs in the inner ear (labyrinth) which regulates the balance, and because the existence of repetitive movement, such as the movement of the car. The movement will be perceived by the brain through the 3 lines on the nervous system, which sends signals from the inner ear (in the form of feelings toward movement, acceleration, and gravity) from the eye (sight), and the deeper tissue on the
