Muscles and Fascia of the Trunk
Abdominal Regions

The hypochondriac region (regio hypochondriaca, hypochondrium) is a paired region bounded superiorly by the costal margin, inferiorly by a horizontal line connecting the lowest points of the tenth Ribs, and medially by the lateral margin of the rectus abdominis Muscle.

The epigastric region (regio epigastrica) is an unpaired region bounded superiorly by the xiphoid process and costal margins, inferiorly by a horizontal line connecting the lowest points of the tenth ribs, and laterally by the lateral margins of the rectus abdominis Muscles.

The lateral region (regio lateralis) is a paired region bounded superiorly by a horizontal line connecting the lowest points of the tenth ribs, inferiorly by a horizontal line connecting the anterior superior iliac spines, medially by the lateral margin of the rectus abdominis muscle, and laterally by a vertical line drawn perpendicularly from the end of the 11th rib to the iliac crest.

The umbilical region (regio umbilicalis) is an unpaired region located inferior to the epigastric region and bounded superiorly by a horizontal line passing through the lowest points of the tenth ribs, inferiorly by a horizontal line connecting the anterior superior iliac spines, and laterally by the lateral margins of the rectus abdominis muscles.

The inguinal region (regio inguinalis) is a paired region bounded superiorly by a horizontal line connecting the anterior superior iliac spines, inferiorly by the inguinal ligament, and medially by the lateral margin of the rectus abdominis muscle.

The pubic region (regio pubica) is an unpaired region located above the Pubic Symphysis. It is bounded superiorly by a horizontal line connecting the anterior superior iliac spines, and laterally by lines drawn along the lateral margins of the rectus abdominis muscles.
