Eye Anatomy in 3 Minutes - After Video Activity

What is the primary function of the eye's photoreceptors?

• Deflect impacts
• Detect light
• Control eye movement
• Supply blood to the retina

Which anatomical layer of the eye includes the cornea and sclera?

• Vascular layer
• Inner layer
• Fibrous layer
• Retinal layer

What is the function of the sclera?

• Bends light's path
• Provides attachment site for extraocular muscles
• Supplies blood to the retina
• Controls pupil size

Which structure changes shape to alter the focal length of the eye?

• Cornea
• Iris
• Lens
• Sclera

What are the three components of the eye's vascular layer?

• Cornea, sclera, retina
• Ciliary body, choroid, iris
• Lens, retina, optic nerve
• Vitreous body, aqueous humor, hyaloid canal

What is the role of the iris in the eye?

• Supplies blood to the retina
• Controls the pupil size
• Provides sharp visual acuity
• Detects photons

What is produced by the ciliary body?

• Aqueous humor
• Vitreous body
• Photoreceptors
• Sclera

Where are photoreceptors located in the eye?

• Sclera
• Cornea
• Retina
• Iris

What is the fovea centralis known for?

• Producing aqueous humor
• Controlling pupil size
• High photoreceptor density
• Absorbing stray light

What is the blind spot in the eye?

• Area with high photoreceptor density
• Where the optic disk sends signals via the optic nerve
• Area that absorbs light
• Attachment site for extraocular muscles
