These questions were not submitted by the lecturer.
1. The orbital septum is an extension of the periosteum at the orbital rim.
2. The superior tarsal muscle is in "parallel" with the tendon of levator palpebrae superioris.
3. The sphenoid bone contributes to the superior border of the inferior orbital fissure.
4. The frontal bone defines the superior border of the superior orbital fissure.
5. The lacrimal fossa for the lacrimal sac is a feature of the lacrimal bone.
6. The four rectus muscles, but not levator palpebrae superioris or the superior oblique muscles, take origin from the annulus tendineus.
7. The superior tarsal muscle is skeletal and innervated by the parasympathetic nervous system.
8. The abducens nerve innervates a single muscle; the medial rectus.
9. The divisions of the oculomotor nerve enter the orbit by passing through the heads of origin of the lateral rectus muscle.
10. The lacrimal, frontal, and trochlear nerves are the most superior in the orbit and do not pass through the annulus tendineus.
11. The cell bodies that mediate corneal pain are located in the ciliary ganglion.
