what is the general function of the middle ear?

The primary function of the middle ear is to efficiently transfer acoustic energy from compression waves in air to fluid–membrane waves within the cochlea.

Answer and Explanation: The Eustachian tube in a frog leads from the pharynx to the middle ear. In vertebrates, the middle ear is the chamber between the tympanic membrane...

The middle ear bones then transfer the vibrating signals to the inner ear. The tympanic membrane is made up of a thin connective tissue membrane covered by skin on the outside and mucosa on the internal surface.

In summary then, anatomically, the ear consists of a sound conducting mechanism and a sound transducing mechanism. The sound conducting mechanism has two parts, the outer ear consisting of the pinna and ear canal, and the middle ear consisting of the tympanic membrane.

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.

It's also known as the pinna or auricle. The outer ear's shape helps to collect sound and direct it inside the head toward the middle and inner ears. Along the way, the shape of the ear helps to amplify the sound — or increase its volume — and determine where it's coming from.

The purpose of the auditory ossicles (also called the ossicular chain) is to transmit sound via a chain reaction of vibrations that connects the eardrum to the inner ear and cochlea.

Eustachian tubes are small tubes that run between your middle ears and the upper throat. They are responsible for equalizing ear pressure and draining fluid from the middle ear, the part of the ear behind the eardrum. The eustachian tubes are usually closed except for when you chew, swallow, or yawn.

Otosclerosis is the most common cause of middle ear hearing loss in young adults. It typically begins in early to mid-adulthood. It is more common in women than in men. The condition may affect one or both ears.

The ears, nose, and throat are located near each other and have separate but related functions. The ears and nose are sensory organs, which are necessary for the senses of hearing, balance, and smell.

The outer ear includes the pinna and the external auditory meatus, the ear canal. These focus sound onto the tympanic membrane, which begins the middle ear. The air-filled middle ear contains three tiny bones, the ossicles (malleus, incus, and stapes), that transmit vibrations of the tympanic membrane to the inner ear.

The tympanic membrane divides the external ear from the middle ear. Middle ear (tympanic cavity), consisting of: Ossicles. Three small bones that are connected and transmit the sound waves to the inner ear.

The eustachian tube (pharyngotympanic tube) connects the middle ear cavity with the nasopharynx. It aerates the middle ear system and clears mucus from the middle ear into the nasopharynx. Opening and closing functions of the eustachian tube are physiologically and pathologically important.

Ossicles. The middle ear contains three tiny bones known as the ossicles: malleus, incus, and stapes. ... The ossicles are classically supposed to mechanically convert the vibrations of the eardrum into amplified pressure waves in the fluid of the cochlea (or inner ear), with a lever arm factor of 1.3.

The Eustachian tube is a narrow tube which links the back of the nose to the middle ear. It is normally closed but opens when we swallow, yawn or chew.

Fluid and mucus flows from the ear to the back of the throat through this tube, where it's swallowed. But instead of flowing down the throat, fluid and mucus can sometimes become trapped in the middle ear and clog the ear. This blockage usually accompanies an infection, such as the common cold, influenza, or sinusitis.

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 inner ear also contains the receptors for sound which convert fluid motion into electrical signals known as action potentials that are sent to the brain to enable sound perception.
