Session 6 lecture: root of the neck

Neck: root, prevertebral region & great vessels
Curricular Objectives
By the end of this session students are expected to:
Theory
1. Define the root of the neck and List its content
2. Summarize the location, attachments and nerve supply of Scalenus anterior
3. Recall the location and attachments of Scalenus medius
4. Name the structures related to Scalenus anterior at the root of the neck
5. Review the extensions of prevertebral fascia and the structures deep to it
6. Describe formation, course and tributaries of the Subclavian vein
7. Acknowledge the risk of Subclavian vein thrombosis and its effects on upper limb
8. Name the structures encountered by the needle during Subclavian vein catheterization (infra-clavicular approach)
9. Discuss the course, parts, and branches of the Subclavian artery
10. Discuss the difference in the course of the vertebral vessels
11. Recall the surface anatomy of 3rd part of Subclavian artery and its clinical importance
12. Recall the attachment of suprapleural membrane and its role in respiration
13. Clarify the association between pleura, lungs and penetrating injuries of the neck
14. Outline the location, course & ganglia of cervical part of sympathetic trunk.
15. Review the distribution of cervical sympathetic ganglia.
16. Summarize the cervical course and the body regions drained by the thoracic duct
17. Define cervical rib and discuss its effects
Practical
1. Locate the root of the neck and distinguish its bounding structures
2. Identify the Scalenus anterior muscle & acknowledge its importance as a key muscle
3. Recall the structures related to Scalenus anterior at the root of the neck
4. Follow the course of Subclavian vein noting its relation to Scalenus anterior & clavicle
5. Palpate to locate the site for Subclavian vein catheterization (infra-clavicular approach) Using the surface landmarks.
6. Trace the Subclavian artery noting the difference in origin between right and left sides
7. Divide the Subclavian artery into three parts by its relation to Scalenus anterior
8. Recognize the branches of the 1st part of Subclavian artery
9. Mark the site used to compress the third part of Subclavian artery to stop bleeding
10. Distinguish the cervical part of the sympathetic trunk noting its three ganglia
11. Label the thoracic duct noting its variable termination
12. Differentiate the course of phrenic nerve from that of Supraclavicular nerves
