Which component of the eye is primarily responsible for its structure and shape?

• A. Ciliary body
• B. Cornea
• C. Globe
• D. Sclera

Answer: (C)

Think of the eye as a single organ—the globe—that sets its overall size and outer contour. The eyeball provides the framework that houses all the internal parts, so it largely defines the eye’s shape. The sclera helps maintain that shape as the tough outer coat, but it’s part of the globe rather than standing apart as the determinant of the eye’s form. The cornea shapes light entry on the front, influencing focusing, while the ciliary body works inward for accommodation and fluid production. So, the eyeball itself—the globe—best explains the eye’s structure and shape.
