Eardrum Not to be confused with the secondary tympanic membrane of the round window. In human anatomy, the eardrum, or tympanic membrane, is a thin, cone-shaped membrane that separates the external ear from the middle ear in humans and other tetrapods. Its function is to transmit sound from the air to the ossicles inside the middle ear, and then to the oval window in the fluid-filled cochlea. Hence, it ultimately converts and amplifies vibration in air to vibration in fluid. The malleus bone bridges the gap between the eardrum and the other ossicles.

The Human Ear 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 also channels sound waves that reach the ear through the ear canal to the eardrum of the middle ear.

Ear Noises Explained Tube Troubles. The Eustachian tube is a small passageway from your inner ear to the back of your nose, and plays an important part in the hearing process. Every time you swallow, yawn, or blow your nose, the Eustachian tube opens and allows air to pass from the middle of your ear to the back of your nose. This process equalizes the pressure in our ears, and prevents the eardrum from bulging in or out too much.

What Is the Function of the Eardrum? The function of the eardrum, also called the tympanic membrane, is to carry sound waves to bones that are located in the middle ear. These bones are called ossicles.

Ruptured Eardrum The eardrum works with the middle and inner ear to help you hear. The eardrum conveys sounds to your brain. It also protects the middle ear from bacteria, water and foreign objects. A ruptured eardrum (tympanic membrane) is an opening or hole in the eardrum. Damage to the eardrum may harm hearing. Patients can be seen by Texas Children's experts in Ear Nose and Throat (Otolaryngology).

Perforated Eardrum The eardrum is a thin membrane that separates your ear canal (the part that is open to the outside) from your middle ear. The eardrum, also called the tympanic membrane, is involved in hearing. Sound waves cause your eardrum to vibrate. This begins the process of converting the sound waves into an impulse that travels to your brain, where it is recognized as sound.

- The middle ear begins at the inner surface of the eardrum. It is connected to a chain of three small bones called the ossicles. Their names are the malleus (hammer) incus (anvil) and stapes (stirrup) since they resemble those objects in shape. Their purpose is to act as a mechanical transformer.

- Prediabetes means that your blood sugar level is higher than normal but not yet high enough to be classified as type 2 diabetes.Without intervention, prediabetes is likely to become type 2 diabetes in 10 years or less.If you have prediabetes, the long-term damage of diabetes — especially to your heart and circulatory system — may already be starting.There's good news, however.rogression from prediabetes to type 2 diabetes isn't inevitable. With healthy lifestyle changes — such as eating healthy foods, including physical activity in your daily routine and maintaining a healthy weight — you may be able to bring your blood sugar level back to normal.

Ear Infections & Surgical Treatment The eardrum may need to be replaced and various tissue grafts may be used to replace it. These include the covering of the muscle from above the ear (fascia) and covering of ear cartilage (perichondruim), or covering from the skull (pericranium).

Ear 1 It is also the location of the Eustachian tube, which equalizes the air pressure between the inner and outer surfaces of the tympanic membrane (eardrum).  Inner ear: The inner ear, also called the labyrinth, operates the body’s sense of balance and contains the hearing organ. A bony casing houses a complex system of membranous cells. The inner ear is called the labyrinth because of its complex shape.

- The Outer or External Ear The external ear consist of two portions, the first being the pinna, the skin covered flabby cartilage of the ear visible on both sides of the head. The basic function of the outer ear or pinna is to protect the eardrum (tympanic membrane).

What is the eardrum made of? Best Answer: The eardrum itself is called a membrane which means it is like a thin piece of material stretched tight over the ear canal and it separates the middle ear from the outer ear. In biology a membrane is a layer that separates two structures-in this case, the middle ear and the outer ear.

- Most of the time your ears will discharge ear wax—an oil that your body naturally produces (UMMC). Ear wax’s job is to make sure that dust, bacteria, or other foreign bodies do not get into your ear. However, other conditions—such as a ruptured eardrum—can cause blood or other fluids to drain from your ear.

Perforated Eardrum A hole or rupture in the eardrum, a thin membrane that separates the ear canal and the middle ear, is called a perforated eardrum. The medical term for eardrum is tympanic membrane. The middle ear is connected to the nose by the Eustachian tube, which equalizes pressure in the middle ear. A perforated eardrum is often accompanied by decreased hearing and sometimes liquid discharge. The perforation may be accompanied by pain, if it is caused by an injury or becomes infected.

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.

- The outer ear, the part that is visible on the side of your head, is called the pinna or auricle. It's made of tough cartilage covered by skin. The pinna's main job is to gather sounds and funnel them to the ear canal, which leads to the middle ear.

Ear, Nose, and Throat Facts Eustachian tube. A canal that links the middle ear with the back of the nose. The eustachian tube helps to equalize the pressure in the middle ear. Having the same pressure allows for the proper transfer of sound waves. The eustachian tube is lined with mucous, just like the inside of the nose and throat.

- A frog’s tympanic membrane, or tympanum, is the circular patch of skin directly behind its eye that we commonly call its eardrum. It functions much like our eardrum does –the tympanum transmits sound waves to the middle and inner ear, allowing a frog to hear both in the air and below water.

Overview A ruptured eardrum — or perforated tympanic membrane as it's medically known — is a hole or tear in your eardrum, the thin tissue that separates your ear canal from your middle ear. A ruptured eardrum can result in hearing loss. A ruptured eardrum can also make your middle ear vulnerable to infections or injury.

That membrane, known as the tympanic membrane, is made of tissue that resembles skin.The eardrum serves two important functions in your ear.nother common cause of a ruptured eardrum is poking the eardrum with a foreign object, such as a cotton-tipped swab or a bobby pin that's being used to clean wax out of the ear canal. Sometimes children can puncture their own eardrum by putting objects such as a stick or a small toy in their ear. 1 | 2 | 3.

Ear 1 Outer ear: The outer ear includes an ear canal that is is lined with hairs and glands that secrete wax. This part of the ear provides protection and channels sound.  Middle ear: Three tiny bones — the malleus, incus, and stapes — within the middle ear transfer sound vibrations from the eardrum to the inner ear.

Extensor pollicis brevis muscle (Redirected from Extensor pollicis brevis). In human anatomy, the extensor pollicis brevis is a skeletal muscle on the dorsal side of the forearm. It lies on the medial side of, and is closely connected with, the abductor pollicis longus.tructure [edit]. The extensor pollicis brevis arises from the radius distal to the abductor pollicis longus, from the interosseous membrane, and from the dorsal surface of the radius.
