The Inner Ear The inner ear contains the sensory organs for hearing and balance. The cochlea is the hearing part of the inner ear. The semicircular canals in the inner ear are part of our balance system. The cochlea is a bony structure shaped like a snail and filled with two fluids (endolymph and perilymph). The Organ of Corti is the sensory receptor inside the cochlea which holds the hair cells, the nerve receptors for hearing.

- Glossary of Ear-Related Terms. A benign tumor that occurs on the acoustic (hearing) branch or vestibular (balance) branch of the 8th cranial nerve. The transmission of acoustic signals through the entire outer, middle and inner ear hearing system. This is the label used for the responses obtained through earphones.

Ear The outer ear consists of the pinna, the part you can easily see and feel, and the ear canal. The pinna helps to gather the sound waves around us. These sound waves travel down the ear canal where they strike the ear drum. The ear drum separates the outer and middle ear.

Autoimmune Inner Ear Disease Autoimmune inner ear disease (AIED) is the name used to describe the variety of disorders in which the ear is the sole target of an inappropriate attack by the immune system. This disorder differs from other vestibular disorders because medical treatment can succeed when given early and aggressively.

Human ear The outer ear consists of the visible portion called the auricle, or pinna, which projects from the side of the head, and the short external auditory canal, the inner end of which is closed by the tympanic membrane, commonly called the eardrum.

Inner ear The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates, the inner ear is mainly responsible for sound detection and balance.

The Human Ear The ear consists of three basic parts-the outer ear, the middle ear, and the inner ear. Each part of the ear serves a specific purpose in the task of detecting and interpreting sound.he three parts of the ear are shown below. The Outer Ear The outer ear consists of an earflap and an approximately 2-cm long ear canal. The earflap provides protection for the middle ear in order to prevent damage to the eardrum.

- The outer ear is called the pinna or auricle (say: OR-ih-kul). This is the part of the ear that people can see. It's what people pierce to wear earrings and what your friend whispers into when it's time for a secret. The main job of the outer ear is to collect sounds, whether they're your friend's whispers or a barking dog.

External, Middle, and Inner Infections- Is There a Difference? The external part of the ear is only “the edge of the iceberg”. The ear has three different parts – the external ear (which is the part we see), the middle ear (which is behind the ear drum and connects to our sinuses) and the inner ear which is the cochlea that turns sounds to electrical signals sent to the brain.

The Structure of the ear The inner ear is probably the most remarkably intricate piece of the body. It makes hearing possible by converting sound into electrical impulses that then travel along the hearing nerve (the acoustic nerve or auditory nerve) to the brain. The inner ear also plays a major role in balance.

Autoimmune Inner Ear Disease Autoimmune inner ear disease (AIED) is the name used to describe the variety of disorders in which the ear is the sole target of an inappropriate attack by the immune system. This disorder differs from other vestibular disorders because medical treatment can succeed when given early and aggressively.iagnosing an autoimmune disorder as the cause of inner ear symptoms can be difficult. To succeed, a physician must have training and experience in these disorders.

Human Physiology/Print Version eardrum definition. The membrane that divides the outer ear from the middle ear. The vibrations of this membrane in response to sound waves lead to the sensation of hearing. Also called the tympanic membrane.

HEARING AND PERCEPTION The ear contains three sections, the outer, middle, and inner ears. The outer ear consists of the lobe and ear canal, structures which serve to protect the more delicate parts inside. The outer boundry of the middle ear is the eardrum, a thin membrane which vibrates in sympathy with any entering sound. The motion of the eardrum is transferred across the middle ear via three small bones named the hammer, anvil, and stirrup.

The Inner Ear The Inner Ear. The Inner Ear (Cochlea) is where transduction takes place. The Inner Ear: The function of the Outer and Middle ear was to conduct sound energy to the Inner Ear where the actual transduction takes place. The Inner Ear is usually referred to as the Cochlea (in dark green in the picture on the next screen).

Basic Ear Anatomy Some of the middle ear structures may be seen through an especially transparent ear drum, while the inner ear may be evaluated only by CT scans, MRI scans or indirectly by special testing, such as audiometry (hearing tests) or other special tests of inner ear function.

Parts and Components of Human Ear and Their Functions Description and Function. The outer ear is the portion of the ear that sits atop the skull, which is made of flesh and cartilage. It is the visible part which serves to protect the eardrum. It also collects and guides sound waves into the middle ear.

- In so doing, they act as a transformer, converting sound vibrations in the external ear canal into fluid waves in the inner ear. The inner ear chamber contains tiny hearing and balance nerve endings bathed in fluid. The inner ear is a delicate, tissue-lined sense organ, which is encased in an outer hard bony shell. These two parts are suspended within the sponge-like ear bone (temporal bone).
