When a sound is heard the energy from the sound is changed into nerve impulses for the brain to interpret. When we hear a sound, the wave enters the ear canal and causes the eardrum to vibrate. The vibrations then passes through the middle ear which contains three bones that are connected. From there this gets fluid moving into the inner ear. This fluid maneuves through hair like cells which then turns those vibrations to nerve impulses. Those impulses are then moved

made in the eardrum to drain the middle ear of any trapped fluid (“myringotomy”). If necessary, a tympanostomy tube may be inserted so the fluid can continue to drain. A myringotomy is usually required when a person has a dysfunctional Eustachian tube (“Myringotomy Information”). A Eustachian tube connects the middle ear to the nasopharynx and is responsible for draining mucus from the middle ear (Tewfik, et al 289). Myringotomies are also used to help treat ear infections that are not responding to

deaf key in on socialization. Experiencing what deaf people have to go through every single day in their lives was not easy to practice. Wearing earplugs for eight hours was a new experience that I learned a lot from. Having the ear plug in my ear canal created a conductive hearing loss and it could be either congenital or acquired causes. These causes can damage the shape of the pinna. The way I started interacting with people around me was not the same, as well the way they

A properly functioning ear includes a cochlear vestibular system. The oval window allows sound waves into the inner ear scala vestibular through the stapes footplate. The round window involved in the release of the sounds and mechanical energy from the scala tympani. Formation of a third opening or third window between the superior semicircular canal and the middle cranial fossa results in Superior Semicircular Canal Dehiscence Syndrome (SSCD). SSCD was discovered by Minor Et Al in 1998. SSCD can

different parts of our ear working together to convert sound waves of the atmosphere into signals that the brain can interpret as sounds. The ear consists of three main parts: the outer ear (the pinna and the ear canal), the middle ear (the ear drum and three small bones referred to as the ossicles), and the inner ear (the cochlea and the auditory nerve). Sounds from the environment are collected by the pinna of the outer ear and are funneled down the external ear canal toward the ear drum. The sounds

acquired speech ANATOMY AND PHYSIOLOGY OF THE EAR 3 Major parts of the ear * Outer ear * Middle ear * Inner ear * OUTER EAR -Consists of the Auricle (part of the ear that protrudes from the side of the head) until the tympanic membrane (eardrum). -Sound is “collected “ by the Auricle and is funneled through the external auditory canal to the eardrum, which vibrates sending sound waves to the middle ear. * MIDDLE EAR -Consists of the eardrum and 3 tiny bones

Health assessment of the Ear. 1. List the 3 function of the middle ear: conducts sound vibrations from the out ear to the central hearing apparatus in the inner ear. It protects the inner ear by reducing the amplitude of loud sounds. 2. Contrast 2 pathways of hearing bone conduction - conduction of sound waves to the inner ear through the bones of the skull. air conduction - conduction of sound waves to the inner ear through the external auditory canal and middle ear. 3. Differentiate among

external aspect of the ear are seen in a variety of medical disciplines. Dermatologists, othorhinolaryngologists, general practitioners, general and plastic surgeons are regularly consulted regarding cutaneous lesions on the ear. This article will focus on those diseases wherefore surgery or laser therapy is considered as a possible treatment option or which are potentially subject to surgical evaluation. Anatomical characteristics When evaluating skin lesions on the ear, specific anatomical

The human ear performs two functions: hearing and balance. Ears pick up vibrations and then change it into signals that the brain interprets as sound. The inner ear contains the semicircular canals and the vestibular organs which tells the brain about any changes in the position of the head. The brain then sends messages to the various muscles that keep the head and body steady. The human ear is has three parts: the outer ear, the middle ear and the inner ear. The outer ear grabs the sound waves
