Axillary lines.Vertical lines: Midline, lateral sternal line, parasternal line and midclavicular line. Horizontal lines: Level of the
sternal angle, and zipho-sternal line.
Anatomical "lines", or "reference lines," are theoretical lines drawn through anatomical structures and are used to describe anatomical location. The following reference lines are identified in Terminologia Anatomica:
Anterior median line
Lateral sternal line: A vertical line corresponding to the lateral margin of the
sternum.
Parasternal line: A vertical line equidistant from the sternal and mid-clavicular lines.
Mid-clavicular line: A vertical line passing through the midpoint of the
clavicle.
Mammillary line
Anterior axillary line: A vertical line on the anterior torso marked by the
anterior axillary fold.
Midaxillary line: A vertical line passing through the apex of the
axilla.
