axillary line

More specifically, the tube is inserted into the 5th intercostal space slightly anterior to the mid axillary line.

(P) (Scratches at ribs along left axillary line.)

Thus, its surface markings are respectively the left sixth rib superiorly, the left anterior axillary line laterally, and the left costal margin inferiorly.

The anterior axillary line is a coronal line on the anterior torso marked by the anterior axillary fold.

With the patient in full inspiration and then full expiration, percuss the area of the lowest intercostal space (eighth or ninth) in the left anterior axillary line.

The axillary lines are the anterior axillary line, midaxillary line and the posterior axillary line.

The resulting scar runs from the posterior axillary line (when placing your open hands on your hips, the thumbs lie along the posterior axillary line.)

Parallel are the anterior axillary line, which passes through the anterior axillary skinfold, and the posterior axillary line, which passes through the posterior axillary skinfold.
