Answer to Question 1

Correct Answer: 4
Rationale 1: The vitreous humor is the gel-like substance that helps to maintain the shape of the eyeball and keeps the retina in place.
Rationale 2: The smooth muscle fibers of the iris change the diameter of the pupil.
Rationale 3: The lacrimal apparatus produces tears and helps to protect the eye.
Rationale 4: The canal of Schlemm is an opening in the trabecular meshwork or spongy connective tissue that drains the aqueous humor from the anterior chamber into the venous system.
