The Senses

Front

What is the cochlea?

Back

The cochlea is a spiral-shaped, fluid-filled structure in the inner ear that converts sound vibrations into electrical signals for the brain.

Front

What is the function of the retina?

Back

The retina is the back part of the eye that contains photoreceptors (rods and cones) which receive and convert light into neural signals.

Front

What is the optic nerve?

Back

The optic nerve is a bundle of nerve fibers that transmits visual information from the retina to the brain.

Front

What is the role of the lens in the eye?

Back

The lens is a transparent structure that focuses light onto the retina, allowing for clear vision.

Front

What is the tympanum?

Back

The tympanum, or eardrum, is a membrane that vibrates in response to sound waves, transmitting these vibrations to the middle ear.

Front

What are auditory ossicles?

Back

The auditory ossicles are three tiny bones in the middle ear (malleus, incus, stapes) that amplify sound vibrations from the tympanum to the inner ear.

Front

What is the function of the semicircular canals?

Back

The semicircular canals are part of the inner ear that help maintain balance and spatial orientation by detecting rotational movements.

Front

What are photoreceptors?

Back

Photoreceptors are specialized cells in the retina (rods and cones) that detect light and convert it into electrical signals.

Front

What is the iris?

Back

The iris is the colored part of the eye that controls the size of the pupil and the amount of light entering the eye.

Front

What is the cornea?

Back

The cornea is the clear, dome-shaped surface that covers the front of the eye and helps focus light.
