Q1. Which part of the optic nerve lies within the eyeball before fibers emerge through the sclera?
- Cavernous part
- Intracranial part
- Intracanalicular part
- Intraocular part
Q2. Why is the intraorbital optic nerve longer than the straight distance from the globe to the optic canal?
- To enter the superior orbital fissure
- To form the ciliary ganglion
- To permit retinal fibers to decussate in the orbit
- To allow eye movement without excessive stretching of the nerve

Q8. Which structure lies immediately superior to the pituitary gland and can be compressed by an expanding pituitary mass?
- Lateral geniculate nucleus
- Optic chiasm
