What part of the ear is responsible for dynamic equilibrium?

Cristae (semicircular canals) are responsible for dynamic equilibrium. The pinna receives the sound waves and it reaches the tympanic membrane through the meatus. The eardrum vibrates and these vibrations get transmitted to the three ossicles present in the middle ear. Malleus, incus and stapes amplify the sound waves.

What is the structure of the human ear?

A brief description of the human ear along with a well-labelled diagram is given below for reference. Pinna/auricle is the outermost section of the ear. The external auditory canal links the exterior ear to the inner or the middle ear. The tympanic membrane, also known as the eardrum, separates the outer ear from the inner ear.

What is the pathway of sound through the ear?

The sound waves travel first through the ear canal and vibrate the eardrum. Before the sound waves enter the inner ear, the total pressure must be amplified. The ossicles in the middle ear do the job of amplification. Then the cochlea in the inner ear conducts the sound through a fluid.

What are the signs and symptoms of ear problems?

Vertigo, tinnitus, hearing loss, and pain are common symptoms. Tinnitus: Ringing in one or both ears. Usually this is due to damage from noise exposure, or from aging. Cerumen ( ear wax) impaction: Ear wax may block the ear canal and adhere to the eardrum.

What are the causes of disinflation?

It is important to note that inflation is caused by an increase in the supply of money in the economy. Therefore, a slowdown in the economy’s money supply through a tighter monetary policy is an underlying cause of disinflation. In some cases, a slowdown in the rate of inflation can also arise during an economic recession.

What is endendolymph and Eustachian tube?

endolymph:the fluid within the semicircular canals and vestibule (utricle and saccule). Eustachian tube:connects the middle ear space with the throat; maintains equal air pressure on both sides of the tympanic membrane (eardrum).

What are the parts of the ear and their functions?

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.
