Neck: Posterior triangle and the related fascia PPT

Neck: Posterior triangle and the related fascia
Curricular Objectives
By the end of this session students are expected to:

Theory
1. Define the Langer’s lines of the skin and outline its orientation in the neck
2. Describe the superficial fascia of the neck and acknowledge its content
3. Describe the location, attachment, nerve supply & clinical importance of platysma
4. Outline the formation, course and termination of the two superficial veins of neck
5. Summarize the surface markings and clinical importance of external jugular vein
6. Review the boundaries of the posterior triangle and its subdivisions
7. Name the fascia forming the roof of the triangle and summarize its attachment
8. List the content of the triangle and define the nerve point of the neck
9. Review the cutaneous branches of the cervical plexus and their courses
10. Outline the course and the structures supplied by the spinal accessory nerve
11. Name the structures forming the floor of the triangle
12. Describe the lower and lateral extension of the fascial carpet of triangle

Practical
1. Mark the dermatomal areas of the cervical skin
2. Identify the platysma muscle, recall its nerve supply and the fascia enclosing it
3. Trace the two superficial veins of the neck (from formation to termination)
4. Follow the boundaries of the posterior triangles and recognize its fascial roof
5. Locate the occipital & subclavian triangles & the inferior belly of omohyoid muscle
6. Trace the 4 cutaneuos branches of the cervical plexus and the accessory nerve
7. Locate the nerve point of the neck and its surface marking
8. Identify the brachial plexus and the subclavian artery
9. Distinguish the muscles forming the floor of the triangle

? The most common cause of swelling in the posterior triangle is supraclavicular lymph nodes enlargement
? Examination of jugular venous pressure is commonly required during physical examination of cardiac patient
