Session 13: Eye + Ear

Which structure is responsible for most of the eye's refraction (light bending)?

• Lens

• Iris

• Pupil

• Cornea

The fovea centralis is located within which part of the eye?

• Iris

• Optic disc

• Macula lutea

• Ciliary body

Which photoreceptor is concentrated in the fovea centralis and detects color?

• Rods

• Cones

• Otoliths

• Neurons

What is the correct order in which light travels through the eye?

• Cornea → pupil → lens → retina → aqueous humor

• Pupil → cornea → lens → retina → fovea centralis

• Lens → cornea → Retina → pupil → vitreous humor

• Cornea → aqueous humor → pupil → lens → vitreous humor → retina

Which eye disorder results from an eyeball that is too long?

• Myopia

• Hyperopia

• Astigmatism

• Presbyopia

What causes astigmatism?

• Lens stiffening

• Eye too short

• Irregular curvature of the cornea or lens

• Detachment of the retina

Which eye structure changes shape during accommodation?

• Cornea

• Pupil

• Lens

• Retina

The blind spot is also known as the:

• Fovea centralis

• Optic disc

• Macula lutea

• Suspensory ligament

Presbyopia occurs due to:

• Shortening of the eyeball

• Irregular lens shape

• Loss of lens flexibility with age

• Overgrowth of the iris

Which part of the eye controls the size of the pupil?

• Lens

• Retina

• Iris

• Cornea
