midclavicular line

An imaginary median line used to describe locations on the trunk. At its top, it passes through the midpoint of the clavicle, and on a male, it runs just medial to the nipple. It crosses the costal margin near the end of the 9th costal cartilage and it extends to the thigh, passing through the fold of the groin halfway between the anterior superior iliac spine and the symphysis pubis. At one point, the milk line (mammary line) intersects the midclavicular line.
