Eye Anatomy and Function Assessment

The video tutorial covers the anatomy of the eye, focusing on accessory structures like eyebrows, eyelids, conjunctiva, and the lacrimal apparatus. It explains their protective roles and how they maintain eye health. The tutorial also details the extraocular muscles responsible for eye movement and discusses clinical conditions like lazy eye and diplopia, highlighting the importance of muscle coordination.

• To improve vision clarity

Which structure is a transparent mucus membrane covering the cornea?

• Iris

• Sclera

• Retina

• Conjunctiva

What is the main role of the lacrimal apparatus?

• To regulate eye pressure

• To produce and drain tears

• To produce mucus

• To control eye movement

What is the purpose of the lacrimal ducts?

• To produce tears

• To protect the cornea

• To drain tears into the nasal cavity

Which muscle moves the eyeball laterally?

• Medial rectus

• Superior oblique

• Lateral rectus

• Inferior oblique

What is the function of the superior oblique muscle?

• To move the eyeball down and medially

• To move the eyeball up and laterally

• To move the eyeball medially

• To move the eyeball laterally

Which muscle is responsible for moving the eyeball medially?

• Lateral rectus

• Medial rectus

• Superior oblique

• Inferior rectus

What is the role of the inferior oblique muscle?
