Front

What is the cochlea?

Back

The cochlea is a spiral-shaped, fluid-filled structure in the inner ear that is responsible for converting sound vibrations into neural signals.

Front

What is the function of the Eustachian tube?

Back

The Eustachian tube helps to equalize pressure on both sides of the tympanic membrane (eardrum), allowing for proper hearing.

Front

What is the main job of the semicircular canals?

Back

The semicircular canals are responsible for maintaining balance and spatial orientation.

Front

What is the lens of the eye?

Back

The lens is a transparent structure in the eye that focuses light onto the retina.

Front

What type of receptor is responsible for vision?

Back

Photoreceptors are specialized cells in the retina that detect light and enable vision.

Front

What is the function of the retina?

Back

The retina is a layer of tissue at the back of the eye that contains photoreceptors and converts light into neural signals.

Front

What are auditory ossicles?

Back

Auditory ossicles are three tiny bones in the middle ear (malleus, incus, and stapes) that transmit sound vibrations from the eardrum to the inner ear.

Front

What is the role of the sclera?

Back

The sclera is the white outer layer of the eyeball that provides structure and protection.

Front

What is the vitreous humor?

Back

The vitreous humor is a gel-like substance that fills the space between the lens and the retina, helping to maintain the shape of the eye.

Front

What are mechanoreceptors?

Back

Mechanoreceptors are sensory receptors that respond to mechanical pressure or distortion, such as touch and sound.
