The general picture of the anterior axillary line is as follows - it begins at a distance of 2 -5 cm from the point of connection of the clavicle with the sternum. It runs in a straight line parallel to this joint, crosses the anterolateral surface of the shoulder joint, runs along the upper edge of the latissimus dorsi muscle and continues to the armpit, which is anatomically located in the interspinous groove. The width of this line ranges from 7 to 15 mm
