List of anatomical lines

Short description: None

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.
* Posterior axillary line: A vertical line passing through the posterior axillary fold.
* Scapular line: A vertical line passing through the inferior angle of the scapula.
* Paravertebral line: A vertical line corresponding to the tips of the transverse processes of the vertebrae.
* Posterior median line

Other anatomical lines include:

* Mid-pupillary line: A line running vertically down the face through the midpoint of the pupil when looking directly forward.
* Mid-inguinal point: A point midway between the anterior superior iliac spine and the pubic symphysis.
* Intercristal line: A transverse line passing across the lumbar spine between the superior aspects of the iliac crests.
* Mid-dorsal line: The intersection between the dorsal skin and the median plane.
* Mid-ventral line: The intersection between the ventral skin and the median plane.
