Study Notes
Dividing the Abdomen
- The abdomen is divided into four quadrants by two vertical planes (midclavicular lines) and one horizontal plane (transumbilical plane).
- The two vertical planes used to divide the abdomen are the midclavicular lines, which run from the midpoint of the clavicle (collarbone) downwards.
Regions of the Abdomen
- The abdomen is divided into nine regions using two horizontal planes (subcostal and transtubercular) and two vertical planes (midclavicular lines).
- The nine regions of the abdomen are: right hypochondriac, epigastric, left hypochondriac, right lumbar, umbilical, left lumbar, right iliac, hypogastric, and left iliac.
Organ Locations
- The liver is located in the right hypochondriac region.
- The stomach is located in the epigastric region.
- The spleen is located in the left hypochondriac region.
- The urinary bladder is located in the hypogastric region.
Planes and Landmarks
- The transumbilical plane runs through the umbilicus (navel) and is used to divide the abdomen into upper and lower parts.
- The transtubercular plane runs through the tubercles of the iliac crest and the body of the fifth lumbar vertebra.
- The subcostal plane is a horizontal line taken from the inferior parts of the lowest costal cartilages.
Quadrants
- The right upper quadrant (RUQ) contains the right lobe of the liver.
- The left upper quadrant (LUQ) contains the stomach.
- The left lower quadrant (LLQ) contains the urinary bladder.
Other Regions
- The umbilical region is central and has the umbilicus as its center point.
- The hypogastric region is located below the umbilical region.
- The right hypochondriac region contains the liver, which filters the blood.
