Objectives-Identify the following structures: humerus (medial & lateral epicondyles, lateral condyle (capitulum), medial condyle (trochlea), radius (head, styloid process, tuborosity), ulna (olecranon, coronoid process, styloid process) -Describe the movements of flexion and extension of the elbow joint. -Describe the articulation of the elbow joint with the radius and ulna. -Explain where you would aspirate a joint effusion. -Describe the course of neurovascular structures in the arm (brachial artery and vein, nerves - medial, ulnar and radial), and their relation in the cubital fossa-Name and identify the anatomical region of the cubital fossa (location, boundaries)

Cubital Fossa
Contents
Lateral to medial, the Bicipital tendon, the Brachial artery, and the Median nerve. The Brachial veins may be removed. You should look for the branching of the Brachial a. into Radial and Ulnar aa. and the Superficial branch of the Radial nerve running underside Brachioradialis muscle
