Session 4: carotid triangle ppt

Carotid triangle
Curricular Objectives
By the end of this session students are expected to be able to:

Theory
1. Describe the location, boundaries, roof and floor of triangle
2. List the content of the triangle
3. Discuss the formation, extension, and content of the carotid sheath
4. Outline the origin, course and important relations of the common carotid artery
5. Compare the courses of internal & external carotid arteries
6. Describe the site, vertebral level, and function of carotid sinus and body
7. Discuss the formation, tributaries and surface markings of internal jugular vein (IJV)
8. Give a simple Definition of (air embolism) and discuss why the IJV is at higher risk
9. Review the course and main branches of the vagus nerve within the triangle
10. List the branches of external carotid artery
11. Summarize the course of each branch of external carotid A (landmarks & distribution)

Practical
1. Locate the carotid triangle and its bounding structures
2. Identify the common carotid artery, its bifurcation and the two terminal branches
3. Distinguish the internal jugular vein and its main tributaries
4. Relate the common carotid artery to carotid tubercle
5. Recognize the branches of external carotid artery
6. Distinguish the carotid sinus and its vertebral level
7. Trace the three cranial nerves found in the triangle (CN: X, XI, XII)
8. Discriminate between the roots and loop of ansa cervicalis
9. Feel the pulse of the common carotid artery
10. Mark the course of internal jugular vein using surface landmarks
