angle of Louis
Describe how you can determine the sternal angle from the hollow curve on your neck
Suprasternal notch - 5cm down - Ridge joining the manubrium to body of sternum
Locate the intercostal spaces from the angle of louis
Move laterally - adjacent 2nd rib and costal cartilage - walk down the interspaces one space at a time on an oblique line

Midclavicular line
Line that drops vertically from the anterior and posterior axillary folds respectively
Anterior and posterior axillary lines

Anteriorly, the apex of the lungs rises about (1) above the (2) of the clavicle
- 2cm to 4cm
- inner third
Anteriorly, the lower border of the lung crosses the (1a) at the (1b), and the (2a) at the (2b)
1a. 6th rib
1b. midclavicular line
2a. 8th rib
2b. midaxillary line
Posteriorly, the lower border of the lung lies at about the level of the (1) spinous process. On (2), it descends farther
