The Eye & Ear (Science Flashcardz)

Front

What are hair cells?

Back

Hair cells are specialized sensory cells located in the cochlea of the inner ear that convert sound vibrations into nerve signals.

Front

What is the cornea?

Back

The cornea is the transparent front part of the eye that covers the iris and pupil, allowing light to enter the eye.

Front

Where do signals from the cochlea go?

Back

Signals from the cochlea are sent to the brain for processing.

Front

What is the eardrum?

Back

The eardrum is a thin membrane that vibrates when sound waves hit it, transmitting sound to the inner ear.

Front

What is the retina?

Back

The retina is the light-sensitive layer at the back of the eye that receives light and converts it into neural signals.

Front

What is the function of the pupil?

Back

The pupil is the opening in the center of the iris that regulates the amount of light entering the eye.

Front

What role does the lens play in vision?

Back

The lens focuses light onto the retina, helping to create a clear image.

Front

What is the function of the cochlea?

Back

The cochlea is a spiral-shaped organ in the inner ear that converts sound vibrations into nerve signals.

Front

What is the pinna?

Back

The pinna is the visible part of the ear that helps to collect sound waves and direct them into the ear canal.

Front

What is sound wave vibration?

Back

Sound wave vibration refers to the oscillation of air particles that creates sound, which is detected by the ear.
