Study Notes
Orbital Anatomy and Function
- Structures not found in the orbits include the nasal cavity and the brain.
- The orbital opening is guarded by the orbital margins, which include the frontal and maxillary bones.
- The orbits contain several components: the eyeball, extraocular muscles, fat, and the lacrimal apparatus.
- Key structures found in the orbits include the optic nerve, vascular components, and connective tissue stabilizing the eyeball.
- Movable folds in the orbits, such as the conjunctival folds, allow for the movement and protection of the eyeball, providing flexibility during eye movement.
- The primary role of the lacrimal apparatus is to produce, distribute, and drain tears, facilitating lubrication and protection of the eyeball.
