Session 13/ checklist: Orbital region

Orbital region
Curricular Objectives
By the end of this session students are expected to:
Theory
1. Define the orbital region and review the location of its main content
2. Recall the location, boundaries and landmarks of orbit and the spaces related
3. Outline the layered structure of the eyelids and the muscles acting on it
4. Describe the conjunctival sac and its functional importance
5. List the structures of the lacrimal apparatus and acknowledge their function
6. Summarize the nervous control of lacrimation
7. List the main content of the orbital cavity
8. Underline the names, attachment, action and nerve supply of extra ocular muscles
9. Paraphrase the process of eye blinking, its anatomical control & functional importance
10. Outline the three coats of the eye ball and their subdivisions
11. Discuss the structure & nutrition of the cornea & its importance in the process of vision
12. Summarize the parts and functions of the ciliary body
13. Review the two muscles of the iris, their actions and nerve supply
14. Describe the different parts of the retina and its role in the process of vision
15. Outline the cavities and other content within the eye ball
16. Review the structure, attachment and function of the lens
17. Discuss the applied anatomy of corneal, accommodation and light reflexes
Practical
1. Label the major content of the orbital region
2. Identify major landmarks and foramina within the orbital cavity
3. State the main structures passing through major foramina of the orbit
4. List and locate the main spaces adjacent to the orbital cavity
5. Mark the parts of the eyelids & name the space with which upper eyelid communicates
6. Label the muscles contributing to eye blinking and state their nerve supply
7. Recognize the conjunctival sac and its parts
8. Locate the different parts of lacrimal apparatus & name the nerve supplying the gland
9. Distinguish the extra ocular muscles and state the nerve supply of each
10. Trace the optic nerve and state its function
11. Identify the three coats of the eye ball and their different parts
12. Locate the eye structures involved in corneal, light and accommodation reflexes
13. State the nerves involved in corneal reflex
14. Label the structures of living human eye visible by direct inspection
