What are the three main layers of the eye?
Flip card
The three main layers are the sclera (outer layer), choroid (middle layer), and retina (inner layer).
What is the role of the cornea in vision?
Flip card
The cornea helps to focus light onto the retina by bending (refracting) the incoming light.
What is the function of the pupil in the eye?
Flip card
The pupil regulates the amount of light that enters the eye by adjusting its size.
How does the lens of the eye contribute to vision?
Flip card
The lens further focuses light onto the retina, allowing for clear vision at various distances.
What is the retina and what is its role in the sensory system?
Flip card
The retina is a layer of tissue at the back of the eye that contains photoreceptor cells, which convert light into electrical signals.
What are the two types of photoreceptor cells in the retina?
Flip card
The two types are rods and cones.
What is the function of rod cells in the retina?
Flip card
Rod cells are responsible for vision in low light conditions and peripheral vision.
