- The basic function of the outer ear or pinna is to protect the eardrum (tympanic membrane). The outer ear also functions to collect sound waves to the eardrum through the ear canal. The second component of the external ear is the auditory ear canal or meatus.

The Auditory System Phase Angle. The Auditory System. Outer Ear. • The outer ear is comprised of the pinna (given the Latin origins, the plural is pinnae) and external auditory canal (also called the external auditory meatus). The eardrum (also called the tympanic membrane) marks the transition between the outer ear and the middle ear. Middle Ear.

Inner ear The inner ear is the innermost part of the vertebrate ear. In vertebrates, the inner ear is mainly responsible for sound detection and balance. In mammals, it consists of the bony labyrinth, a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea, dedicated to hearing; converting sound pressure patterns from the outer ear into electrochemical impulses which are passed on to the brain via the auditory nerve. The vestibular syst

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.he inner ear is found in all vertebrates, with substantial variations in form and function. The inner ear is innervated by the eighth cranial nerve in all vertebrates.

Basic Ear Anatomy The external ear is made up of the auricle, the external auditory canal (ear canal) and the outer surface of the ear drum or tympanic membrane. The auricle functions to collect and amplify sounds in the environment and aids in determining the direction from which a sound is coming.

Each region of the ear contains structures that play a vital role in your hearing and balance. The eardrum is a thin membrane that separates the outer ear (ear canal) from the middle ear. Sound waves vibrate the eardrum. A perforation (hole) in the eardrum may occur as a result of infection, trauma (e.g. swab puncture, waterskiing injury, etc.), or other problems.

Ear The outer ear consists of the pinna and the ear canal. Since the outer ear is the only visible portion of the ear in most animals, the word ear often refers to the external part alone. The middle ear includes the tympanic cavity and the three ossicles.

- Audiology Externshipsand Jobs. The ear is made up of three parts: the outer, middle, and inner ear. All three parts of the ear are important for detecting sound by working together to move sound from the outer part through the middle and into the inner part of the ear.

Ear anatomy and physiology Hearing consists of two components: identification of sounds (what the sound is) and localisation of those sounds (where the sounds are coming from). The ear is divided into three main parts – the outer ear, the middle ear, and the inner ear. The inner ear is filled with fluid.

The outer ear includes the pinna, the visible part of the ear, as well as the ear canal which terminates at the eardrum, also called the tympanic membrane.

- In general, the ear consists of three major sections: the outer, middle and inner ear. Sound is collected by the outer ear and funneled down the ear canal (outer ear). The sound vibrations cause movement of the eardrum and the chain of three tiny bones connected to it (middle ear).The middle ear system serves to intensify the energy of the sound vibrations and delivers them to the cochlea (inner ear).ound is collected by the outer ear and funneled down the ear canal (outer ear).

What Is the Carbon Cycle? - Diagram, Process & Definition The carbon cycle is the process by which carbon moves from the atmosphere into the Earth and its organisms and then back again. Gain a deeper understanding of how the carbon cycle works in this lesson.arbon is also found abundantly in our atmosphere in the form of carbon dioxide, or CO2. Additionally, carbon is also trapped within the Earth in the form of fossil fuels. The carbon cycle is essentially nature's way of reusing carbon atoms in different ways and in varying places.

What is the eardrum made of? The outer ear refers to the ear canal that is approximately one inch in length and ends at the level of the eardrum (known as the tympanic membrane). The eardrum identifies the beginning of the middle ear, which is a cavity in the bone of the skull that houses the three bones of hearing (known as ossicles).

Each region of the ear contains structures that play a vital role in your hearing and balance. The ear canal is lubricated by glands in the skin that secrete wax. The wax may plug the canal, causing a loss of hearing. An infection of the ear canal skin can cause inflammation and painful swelling. Antibiotics are generally used to treat these infections.

What structures are responsible for balance and sound in the ear? The anatomy of the ear can be a little confusing, especially since the ear is responsible not only for hearing, but also for balance. There are three components to the ear: the outer ear, the middle ear and the inner ear. All three are involved in hearing but only the inner ear is responsible for balance. The outer ear is composed of the pinna, or ear lobe, and the external auditory canal. Both structures funnel sound waves towards the ear drum or tympanic membrane allowing it to vibrate. The pinna is also responsible for protecting the ear drum from damage. Modified sweat glands in the ear canal form ear wax.

- 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.

The Inner Ear: Sense of Balance and Hearing The Cochlea. The cochlea is a fluid-filled structure in the inner ear responsible for converting the vibrations of sound waves into electrochemical impulses known as action potentials. As the ossicle called the stapes moves the oval window in and out, it causes the oval window to compress the fluid in the cochlea.

2 Structure and function 2.1 Structure and function of the outer and middle ear. Figure 1 is a diagram of the human ear. The outer ear consists of the visible part of the ear or pinna, the external auditory canal (meatus), and the tympanic membrane (tympanum) or eardrum. The human pinna is formed primarily of cartilage and is attached to the head by muscles and ligaments.

- The human ear has three main sections, which consist of the outer ear, the middle ear, and the inner ear. Sound waves enter your outer ear and travel through your ear canal to the middle ear. The ear canal channels the waves to your eardrum, a thin, sensitive membrane stretched tightly over the entrance to your middle ear. The waves cause your eardrum to vibrate. It passes these vibrations on to the hammer, one of three tiny bones in your ear. The hammer vibrating causes the anvil, the small bone touching the hammer, to vibrate. The anvil passes these vibrations to the stirrup, another small bone which touches the anvil.
