Anatomy: Musculoskeletal 3

Aim

Become familiar with the anatomy of the upper limb including the shoulder and elbow joints and their movements.

Outcomes

1. Describe how the humerus, scapula and clavicle are articulated.

2. Identify the surface landmarks of the region.

3. Identify the following:

a. The continuity of the structures in the root of the neck and the axilla, brachial plexus, subclavian and axillary veins and arteries

b. The walls and contents of the axilla

4. Locate the brachial plexus in the axilla and draw a diagram to illustrate the formation of the brachial plexus and the relationships of the cords to the axillary artery.

5. Explain the clinical significance of the arterial anastomosis around the scapula.

6. Identify the major features of the shoulder joint.

7. List the movements of the shoulder joint, the muscles groups involved and the spinal root values responsible for each movement.

8. Explain how stability at the shoulder joint is maintained, and some of the common injuries.

9. Identify the muscle groups involved in extension of the elbow.

10. Demonstrate and test flexion and extension at the elbow, supination and pronation, and list the spinal segmental root values involved in these movements and in the biceps and triceps tendon reflexes.

11. Trace the course of the radial nerve and indicate where it is most likely to be injured and explain the effects of damage.

12. Examine the articulation of the humerus, radius and ulna at the elbow and study the main features of the joints.

13. Draw the dermatome map of the upper limb.

14. Explain the d
