Name parts of the eye
you already know

What do we
call this reflex?

1. Light reflex
2. Iris reflex
3. Pupil reflex
4. Light protection

New theories this lesson

parts of the eye
accommodation
sensory receptor cells

Route for light stimulus: Cornea, pupil, lens, vitreous body, retina, optic nerve

Accommodation 

Means: The possibility for the eye to focus on things nearby or further away

Two situations

A: Far point - lens has to be flat = concave

B: Near point - lens has to be more 'round' = convex

Different sensory receptor cells

Recap

Cones are for: Color (red / blue / green)

Rods are for: Light (black / white)

What do you want me to explain once more?

Which cells receive light

1. Cones
2. Rods
3. Both
4. None

Which part is not actually an organ inside of the eye?

1. pupil
2. iris
3. vitreous body
4. blind spot

Which part of the eye changes shape by using a circular/ciliary muscle?

1. Iris
2. Pupil
3. Cornea
4. Lens

Being color blind means these cells are not working properly

1. Rods
2. Cones
3. Both
4. None

To focus on your textbook in front of you, your lens needs to be

1. Concave
2. Convex

To focus on something in the far distance, the ciliary muscle around the lens needs to

1. Relax
2. Contract

Which part is easiest to learn?

1. Accommodation
2. Pupilreflex
3. Parts of the eye
4. Cones and rods
