What are the 9 regions of the abdomen?
The nine regions are smaller than the four abdominopelvic quadrants and include the right hypochondriac, right lumbar, right illiac, epigastric, umbilical, hypogastric (or pubic), left hypochondriac, left lumbar, and left illiac divisions. The perineum is sometimes considered to be the tenth division.
What is the abdominal wall called?
Chief layers of the abdominal wall include: Skin, Superficial fascia (the subcutaneous tissue which forms the thin, single layer above the umbilicus. Below the umbilicus, it is divided into two layers (1) the fatty superficial layer called Camper’s fascia and (2) the deep layer called Scarpa’s fascia.
