- 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.

- Unformatted text preview: 373. Explain the function of the auditory tube. The function of the auditory tube ( Eustachian tube ) is to maintain equal air pressure on both sides of the tympanic membrane, which is necessary for normal hearing. 374. Distinguish between the osseous and the membranous labyrinths.

Tympanoplasty The purpose of tympanoplasty is to repair the perforated eardrum, and sometimes the middle ear bones (ossicles) that consist of the incus, malleus, and stapes.Tympanic membrane grafting may be required. If needed, grafts are usually taken from a vein or fascia (muscle sheath) tissue on the lobe of the ear.he purpose of tympanoplasty is to repair the perforated eardrum, and sometimes the middle ear bones (ossicles) that consist of the incus, malleus, and stapes.

Eardrum In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear. 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.[1]

What Is the Function of the Tympanum on a Frog? The tympanum, or ear drum, on a frog transmits sound waves to the inner ear and also prevents water and debris from entering the inner ear. The tympanum on a frog is a large external structure located on either side of the head behind the eye. It is made up of nonglandular skin. Continue Reading.

- Anatomy of the Ear The external ear (or pinna, the part you can see) serves to protect the tympanic membrane (eardrum), collects and directs sound waves through the auditory canal to the eardrum. About 3 cm. long, the canal contains modified sweat glands that secrete cerumen, or earwax.

- What does the ear drum do in your ear? The ear drum (aka: Tympanic Membrane) has several functions. It helps protect our middle ear space from debris and foreign objects, it connects to the middle ear bones (ossicl…es) in order to transmit vibrations that enter the ear canal to the middle ear bones.

Middle ear The Middle Ear is the portion of the ear internal to the eardrum, and external to the oval window of the inner ear. Also mammalian middle ear contains three ossicles, which transfers the vibrations of the eardrum into waves in the fluid and membranes of the inner ear.

Middle ear The cavity also plays a very important role in a person's ability to hear. Inside the middle ear, three small bones (ossicles) form a chain and conduct sound vibrations from the eardrum to the inner ear. Once in the fluid-filled inner ear, sounds are converted into nerve impulses and sent to the brain.

What is the function of the auditory ossicles? The three auditory ossicles are located in the middle ear. Their function is to transmit and amplify the sound vibrations from the tympanic membrane (eardrum) to the oval window. The ears change the high amplitude, low pressure waves of sound in air. into the low amplitude, high pressure waves of sound in water.

âââââââââââââââââââââââââââââââââââââââââââââââThe eardrum is a small membrane at the end of the ear canal. The eardrum collects the sounds that come into the ear canal. These sound waves vibrate the eardrum; the sounds are then transmitted to the bones of hearing (ossicles). The eardrum also protects the middle ear so debris and bacteria do not enter the middle ear. An eardrum perforation is a hole or opening in an otherwise intact eardrum.The size of the perforation can vary from a small pinpoint opening to a loss of the entire eardrum.erforation at margin of the eardrum. This is a perforation that occurs at the margin of the eardrum-where the eardrum and ear canal come together. In some cases, skin from the ear canal can grow through the perforation into the middle ear, forming a cholesteatoma.

ear The middle ear is an air-filled cavity about the size of a pea. It turns sound waves into vibrations and delivers them to the inner ear. The middle ear is separated from the outer ear by the eardrum, or tympanic membrane, a thin, cone-shaped piece of tissue stretched tight across the ear canal.

- 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).

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 Ear Structure/Function PLAY  ONLY. Share this set. The three divisions of the ear function to provide the sense of hearing: -The external ear, from the pinna (or auricle), gathers sounds, which funnel through the external auditory canal. -Sounds reach the tympanum, or eardrum, in the middle ear.

External acoustic meatus The ear canal functions as an entryway for sound waves, which get propelled toward the tympanic membrane, known as the eardrum. When sounds enter the middle ear, they are transmitted to tiny bones called the ossicles, which consist of the stapes, the incus, and the malleus. Sounds are later carried (in the form of waves) to the inner ear.
