The Inner Ear The inner ear which contains the a very important part of the hearing mechanism. This fluid-filled‚ snail-shaped cochlea purpose is to translate incoming sound waves into electrical signals so that the brain can understand its surroundings. The cochlea which is a Latin word for snailed-shell is a coiled‚ tapered tube containing the auditory branch of the inner ear. Its core component is the Organ of Corti‚ that is a cellular layer sitting on top of the basilar membrane for the sensory

stands for the major features of this syndrome. The letter C stands for coloboma of the eye‚ H is heart defects‚ A stands for atresia of the choanae‚ R is retarded growth and development‚ G stands for genital abnormalities and lastly letter E stands for ear anomalies and/deafness. The cause of this syndrome may be genetically heterogeneous‚ but most cases are not regular events of unknown cause. The CHARGE Syndrome is genetically caused by a small deletion of chromosome 8. A tiny region on chromosome

Muscles of the tensor tympani and stapedius serve a protective function by tensing the auditory ossicles preventing damage to the inner ear neurons. 8.The tympanic membrane is composed of epithelial and connective tissues that readily regenerate. The inner ear is mostly composed of neural tissues. Neurons do not heal well and can rarely be replaced. Damage to the inner ear would be permanent if he damaged the receptors in the cochlea (spiral organ)‚ semicircular canals (ampullae)‚ or vestibule (otolithic

It usually begins in the labyrinth of the inner ear‚ and is diagnosed when the growth spreads to the middle ear. The most common presentation attaches the footpad of the stapedius to the oval window‚ which reduces the overall amplitude of vibrations transmitted to the inner ear. Bony growth may also spread to the stapedius crura and the oval window. It is less common to find the growth on the ossicles‚ or occupying a large amount of middle ear space. Otosclerosis is generally not detectable

The Path of Light and Sound By: Kristin Jaskowiak The organ that gives us a sense of sight is our eyes. Of the five senses‚ our eyes allow us to learn the most about our surroundings. It is important to know the structures and anatomy that make up the eyes to gain a better understanding of how light and images are processed to become sight.

While Chiropractic treatment is a gentle adjustment of the cervical spine using neither drugs nor surgery‚ resulting in an effective care in less time. Once the doctor or chiropractor has determined which type of otitis media the patient has a treatment can be started. Otitis Media is the result of inflammation developing in the middle ear in the cavity

The waves that are not absorbed can be perceived by the human ear; of equal importance to the directly intercepted waves are those reflected
