Document Summary
Class and lab objectives: self-review anatomy and physiology. Thoracic cage bony structure with a conical shape, narrower at the top. Sternum, 12 pairs of ribs, 12 thoracic vertebrae. Bottom diaphragm: musculotendinous septum that separates thoracic cavity from the abdomen. Costochondral junctions: where ribs join cartilages (not palpable: identify the anatomy associated with the position and surface landmarks and thoracic cavity. Costochondral junctions: identify the location of the apex and base of the lung anteriorly and posteriorly and locate landmarks for each lobe. Suprasternal notch: u-shaped depression above sternum & b/w clavicles. Sternum breastbone : manubrium, the body, and xiphoid process (serves as a good landmark) Sternal angle angle of louis/ manubriosternal angle articulation of the manubrium and body of the sternum, continuous with 2nd rib trachea bifurcates at this landmark. Diaphragm: musculotendinous septum that separates thoracic cavity from abdomen, contracts when inhaling. Costal angle: costal margins forma an angle at the xiyphoid process typically <90 .
