MSI ANATOMY LAB 9: LEARNING OBJECTIVES Axilla and Brachial Plexus

Review Learning Objectives

1. Trace the flow of lymph from the following organs/structures: palatine tonsils, tongue, lower lip, upper extremities (right and left), breasts (right and left; distinguish quadrant drainage), lungs (right and left), liver, stomach, kidneys (right and left), urinary bladder, lower extremities (right and left), superficial tissues of the abdomen, thorax and back. (MIS, Week 15: Integration of Immune System & Microbes) 2. Identify where in the vascular system lymph is returned to the circulation. (MIS, Week 15: Integration of Immune System & Microbes) 3. Identify where in the body each of the following groups of lymph nodes can be palpated: submental, submandibular, deep cervical chain, axillary, inguinal. (MIS, Week 15: Integration of Immune System & Microbes) 4. Describe the clinical significance of the following lymph nodes: axillary, parasternal, tonsillar, submental, submandibular, supraclavicular. (MIS, Week 15: Integration of Immune System & Microbes) 5. Identify the primary tissues/body regions drained by each of the following major lymphatic trunks of the body: jugular, subclavian, bronchomediastinal, lumbar, intestinal, thoracic duct. (MIS, Week 15: Integration of Immune System & Microbes)

Primary Learning Objectives

1. Describe the location of the axilla, state the structures located within the axilla, and identify the anterior and posterior axillary folds. 2. Describe, identify, and draw the brachial plexus including all of its branches. Recognize brachial plexus injuries and explain their clinical presentation. 3. Identify the dermatomes of the upper limb. Identify the exclusive areas used for testing each dermatome. 4. Name the major nerves that have a sensory distribution to the upper limb. Identify the location where each nerve is tested. 5. Identify the structures that pass through the interscalene triangle of the neck. 6. Define thoracic outlet syndrome (TOS) and identify the structures affected. State the common symptoms of thoracic outlet syndrome. 7. Describe and identify the origin, course and function of the axillary, radial, musculocutaneous, median and ulnar nerves. Name the major muscles and muscle groups that the axillary, radial, musculocutaneous, median and ulnar nerves supply. Predict the consequences of injury to these nerves and describe how to functionally test their integrity. 8. Identify the locations of the sensory domains of the following nerves and/or their branches: axillary, radial, musculocutaneous, medial cutaneous nerve of the arm, medial cutaneous nerve of the forearm, median, ulnar. Identify the locations where each nerve is tested. 9. List the ventral primary rami that contribute to the brachial plexus and describe the distribution of these fibers into superior, middle and inferior trunks. Identify the three cords of the brachial plexus and the branches of each. Identify the spinal nerve components located in each of the five terminal branches of the brachial plexus. 10. Identify a surgical neck fracture of the humerus on radiographic imaging, state the artery and nerve at risk of injury from a fracture at this site, and explain the resulting neurological deficits.
