Ear anatomy

Front

What is the function of the incus in the ear?

Back

The incus, also known as the anvil, is one of the three small bones in the middle ear that transmits sound vibrations from the malleus to the stapes.

Front

What is the outer ear's role in hearing?

Back

The outer ear collects sound waves and directs them into the ear canal towards the eardrum.

Front

What is the cochlear nerve responsible for?

Back

The cochlear nerve transmits auditory information from the cochlea to the brain, allowing for the perception of sound.

Front

What does ENT stand for in medical terms?

Back

ENT stands for Ear, Nose, and Throat, referring to the medical specialty that deals with these areas.

Front

What is the role of the stapes in the auditory system?

Back

The stapes, also known as the stirrup, is the smallest bone in the body and transmits sound vibrations from the incus to the oval window of the cochlea.

Front

What are the three main parts of the ear?

Back

The three main parts of the ear are the outer ear, middle ear, and inner ear.

Front

What is the function of the eardrum?

Back

The eardrum, or tympanic membrane, vibrates in response to sound waves and transmits these vibrations to the ossicles in the middle ear.

Front

What is the role of the semicircular canals?

Back

The semicircular canals are part of the inner ear and are responsible for maintaining balance and spatial orientation.

Front

How does sound travel through the ear?

Back

Sound travels through the ear by entering the outer ear, vibrating the eardrum, moving through the ossicles in the middle ear, and then into the cochlea in the inner ear.

Front

What is the significance of the oval window?

Back

The oval window is a membrane-covered opening that connects the middle ear to the inner ear and transmits vibrations from the stapes to the fluid in the cochlea.
