Six stages of vision

The pupil dilates when it's dark and constricts in bright light.

• True

• False

Where can we find photoreceptors in the eye?

• Cornea

• Aqueous humour

• Retina

• Optic nerve

What causes the lens to change its shape?

• Light

• Pressure from vitreous humour

• Ciliary muscles

• Cones

What is NOT a function of cones

• Night vision

• Responding to high levels of light

• Colour vision

• Day vision

Why do our eyes have a blind spot?

• The lens can't properly bend light on the retina

• The cornea becomes cloudy as we age

• Parts of the retina contain no photoreceptors

• The pupil doesn't contract when light comes in

Which structure transmits sensory information from the retina to the visual cortex?

• Cones

• Optic nerve

• Neurotransmission

• Rods

Reorder the following stages of visual sensation and perception

• Transduction

• Organisation

• Transmission

• Reception

• Interpretation

Stimulus energy is converted by the receptor cells into electrochemical nerve impulses

• Reception

• Transmission

• Optic sensation

• Transduction

Where are feature detectors located?

• Cornea and retina

• Optic chiasm

• Optic nerve and visual cortex

• Somatosensory cortex
