Question

question 19
the optic nerve stems from this region of the eye
○ sclera
○ choroid
○ blind spot of the retina
○ macula lutae

Explanation:

To solve this, we analyze each option:

• Sclera: The tough outer layer of the eye, not where the optic nerve starts.
• Choroid: The vascular layer between sclera and retina, not related to optic nerve origin.
• Blind spot of the retina: This is the area where the optic nerve exits the eye, as there are no photoreceptors here, and the optic nerve fibers gather to form the optic nerve.
• Macula lutea: The central part of the retina for sharp vision, not the optic nerve origin.

Answer:

C. blind spot of the retina
