MSI ANATOMY LAB 11: LEARNING OBJECTIVES Arm and Cubital Fossa

Review Learning Objectives

1. Identify the basilic and cephalic veins, describe their courses through the superficial fascia, and state from which venous structure they originate. (MSI Anatomy Lab 8: Shoulder) 2. Describe the relationship of the tendon of the long head of biceps brachii to the glenohumeral joint. Explain Popeye deformity, bicep tendinitis, and bicep tendon subluxation. (Anatomy Lab 8: Shoulder) 3. Identify the dermatomes of the upper limb. Identify the exclusive areas used for testing each dermatome. (MSI Anatomy Lab 9: Shoulder) 4. Name the major nerves that have a sensory distribution to the upper limb. Identify the location where each nerve is tested. (MSI Anatomy Lab 9: Shoulder)

Primary Learning Objectives

1. Identify the humerus and its following distal osseous features on human bones or radiographic imaging: capitulum, trochlea, medial and lateral epicondyles, medial and lateral supracondylar ridges, olecranon fossa, radial fossa, coronoid fossa, and the groove for ulnar nerve. 2. Identify the radius and its following osseous features on human bones or radiographic imaging: head, neck radial tuberosity, and styloid process. 3. Identify the ulna and its following osseous features on human bones and radiographic imaging: olecranon, trochlear notch, coronoid process, radial notch, ulnar tuberosity, styloid process. 4. Explain how the arm is organized into fascial compartments. 5. Identify the muscles in the anterior and posterior compartments of the arm, state their innervation, and state one action of each muscle. 6. Explain the role of the biceps brachii muscle in pronation and supination of the forearm and identify the joints involved in these movements. 7. Define cubital fossa, identify the structures that form its boundaries, and state its contents. 8. Identify the brachial and deep brachial arteries, describe their course, and state the compartment that each supply. 9. Identify the location where the brachial artery can be compressed to control hemorrhage and where the pulse of the brachial artery is palpated. 10. Explain the clinical significance of median cubital vein and the bicipital aponeurosis when performing venipuncture. 11. Identify and describe the course of the musculocutaneous nerve in the arm, name the structures it innervates, and describe the clinical manifestations of a musculocutaneous nerve lesion occurring in the arm. 12. Identify and describe the course of the ulnar nerve in the arm. 13. Define cubital tunnel, identify its location, and explain cubital tunnel syndrome. 14. Identify and describe the course of the median nerve in the arm and describe the clinical manifestations of a median nerve lesion occurring at the elbow. 15. Define supracondylar fracture and differentiate the nerves at risk of injury when the distal fracture segment displaces in different directions (posterolateral versus posteromedial). 16. Compare the frequency of elbow fractures types expected in children and adults. 17. Identify and describe the course of the radial nerve in the arm, name the structures it innervates, and describe clinical manifestations of radial nerve lesion occurring in the arm. 18. Identify a humeral shaft fracture on a radiograph, explain its relationship to a radial nerve lesion, and describe the clinical manifestations that can result. 19. Identify and describe the path of the medial cutaneous nerve of the arm and describe the cutaneous region of the arm it innervates. 20. Describe the anatomy of the elbow joint complex, list the three joints of which it is composed, and state the motions that occur at each joint. 21. Identify and state the function of the following elbow joint complex ligaments: ulnar collateral, radial collateral, and annular. 22. Explain nursemaid's elbow (subluxation or dislocation of radio-ulnar joint) and student's (olecranon) bursitis.
