Eye and camera parts

Question 1

What is the cornea?

Answer 1

clear structure at the front of the eye that directs light from an object to the pupil.

Question 2

What is the pupil?

Answer 2

opening through which light passes into the eye.

Question 3

What is the iris?

Answer 3

colored, muscular ring of your eye that makes the pupil larger/smaller depending on the amount of light around it.

Question 4

What is the lens?

Answer 4

flexible, convex structure that refracts light from the pupil to the retina.

Question 5

What is the ciliary muscle?

Answer 5

adjusts the shape of the lens to allow it to focus light entering the eye.

Question 6

What is the retina?

Answer 6

a tissue that lines the back of the eye on which images are formed .

Question 7

What is the optic nerve?

Answer 7

sends images formed by the eye to the brain as an electrical system.

Question 8

What are the rod cells?

Answer 8

light receptors found in the retina activated by low levels of light (don’t detect color)

Question 9

What are cone cells?

Answer 9

light receptors found in the retina, activates in bright light, (detects red,blue, green) cones = color

Question 10

Match these camera parts to the eye parts:
Light sensors
aperture
lens
diaphragm
focusing ring

Answer 10

light sensors = retina
aperture = pupil
lens = lens
diaphragm = iris
focusing ring = ciliary muscles
