These planes divide the abdomen into nine regions:
Right hypochondriac.Right lumbar (or flank)Right illiac.Epigastric.Umbilical.Hypogastric (or pubic)Left hypochondriac.Left lumbar (or flank)
Why is it important to know the 9 regions of the abdomen?
Organs in the nine regions of the abdomen
It is important to know the anatomical regions (and quadrants) of the abdomen to correlate the pain to the organs contained in each area. For example, pain within the epigastric region should guide you to think about the stomach, liver, pancreas, duodenum, and adrenal glands.
How do you remember the 9 abdominal regions?
If you need a quick memory trick to keep these regions straight, remember that for the side columns, the names are the same from top to bottom: Hypochondriac, then Lumbar, and then Iliac (HLI). For the middle column, the regions are Epigastric, then Umbilical, and then Hypogastric (EUH).
What are abdominal regions?
The abdomen (colloquially called the belly, tummy, midriff, stomach, tucky or stocham) is the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The abdomen is the front part of the abdominal segment of the torso. The area occupied by the abdomen is called the abdominal cavity.
What is Transtubercular plane?
A lower transverse plane midway between the upper transverse and the upper border of the pubic symphysis; this is termed the intertubercular plane (or transtubercular), since it practically corresponds to that passing through the iliac tubercles; behind, its plane cuts the body of the fifth lumbar vertebra.
What causes pain in umbilical area?
Share on Pinterest An umbilical hernia, acute appendicitis, or a small bowel obstruction can all cause periumbilical pain. Periumbilical pain occurs in the area surrounding and including the belly button. When diagnosing abdominal pain, doctors must know where the pain is located.
What is peritoneal lining?
The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. It covers most of the intra-abdominal (or coelomic) organs, and is composed of a layer of mesothelium supported by a thin layer of connective tissue.
How many abdominal regions are there?
These planes divide the abdomen into nine regions; right and left hypochondriac regions, epigastric region, umbilical region, right and left lateral regions of abdomen, hypogastric region, and right and left inguinal regions. Another way to divide the abdomen is with one vertical and one horizontal line.
How many regions are there in the abdominal?
The abdomen has been bisected, trisected, and even divided into as many as 9 separate regions. The layers of the abdominal wall consist of the skin, superficial fascia, and muscles.
How do you divide the 9 quadrants of the abdomen?
divided into 9 regions by two vertical and two horizontal imaginary planes.

What is the transpyloric plane used for?
The transpyloric plane is clinically notable because it passes through several important abdominal structures. It also divides the supracolic and infracolic compartments, with the liver, spleen and gastric fundus above it and the small intestine and colon below it.
What level is transpyloric plane?
The transpyloric plane, also known as Addison’s plane, is an imaginary axial plane located midway between the jugular notch and superior border of pubic symphysis, at approximately the level of L1 vertebral body.
Where is the interspinous plane located?
a transverse plane passing through the anterior superior iliac spines; it marks the boundary between the lateral and umbilical regions superiorly and the inguinal and pubic regions inferiorly.
