16
Q

What is the function of the iris?

A

contains muscles that control the size of the pupil

17
Q

What is the function of the pupil?

A

an opening in the iris that helps control the amount of light entering the eye (dilates or constricts)

18
Q

What is the function of the lens?

A

focuses light onto the retina, by adjusting its shape according to the distance of the object being viewed (bulges – to focus on nearby objects; flattens – to focus on distant objects)

19
Q

What is the function of the ciliary muscles?

A

control the shape of the lens.

20
Q

What is the function of the retina?

A

Contains photoreceptors (rods and cones). Receives and absorbs lights and processes images.

21
Q

What is the function of Rods?

A

respond to very low levels of light
responsible for night-vision and peripheral vision.
sensitive to movement

22
Q

What is the function of Cones?

A

respond to high levels of light (and do not respond well to dim levels of light).
Detect fine detail and are involved in colour vision.

23
Q

What is the function of the optic nerve/s?

A

transmits the visual information from the retina to the primary visual cortex of the brain (Transmission)

Q
