Neck: Fascia and Posterior triangle
Curricular Objectives
By the end of this session students are expected to be able to:
Practical
1. Identify the platysma muscle and recall its nerve supply.
2. Recognize different layers of deep cervical fascia
3. Locate the retropharyngeal and parapharyngeal spaces
4. Distinguish the sternocliedomastoid and trapezius muscles
5. Follow the boundaries of the posterior triangle
6. Locate the brachial plexus and the subclavian artery
7. Distinguish the muscles forming the floor of the triangle
8. Identify the 4 cutaneuos branches of the cervical plexus and the accessory nerve
Theory
1. Describe the location, attachment, nerve supply of platysma
2. Outline the attachment of different layers of deep cervical fascia
3. Summarize the communications of retro- and parapharyngeal spaces
4. Discuss the boundaries, roof and floor of the posterior triangle
5. List the content of the triangle
6. Describe the distribution of the accessory nerve and its course within the triangle
7. Outline the sensory nerves of the neck
8. Comprehend the superficial course and surface anatomy of external jugular vein.
