Abdominal Quadrants - Lesson 6

Anatomical diagram of the human torso and skeleton highlighting the nine abdominal regions with labels for the hypochondriac, lumbar, inguinal, epigastric, umbilical, and hypogastric regions.
This anatomy diagram gives a clear view of the human abdominal regions. By dividing the abdomen into nine sections (Hypochondriac, Lumbar, Inguinal, Epigastric, Umbilical, and Hypogastric), medical professionals can precisely locate and describe organ-specific symptoms or pathologies.


Abdominal quadrants study is an important things to know. We can divide the abdominopelvic region into four quadrants. This can be imagined by drawing an imaginary lines one vertical and one horizontal through the body. The four abdominal quadrants are right upper quadrant, left upper quadrant, right lower quadrant, left lower quadrant.

1. Right upper quadrant (RUQ): This quadrant contains the right lobe of the liver, gallbladder, part of the pancreas, parts of the small and large intestines.

2. Left upper quadrant (LUQ): This quadrant contains the left lobe of the liver, stomach, spleen, part of the pancreas, parts of the small and large intestines.

Anatomical diagram of the human torso and skeleton highlighting the right lower quadrant (RLQ). Labels point to specific organs including the appendix, parts of the small and large intestines, and the right ovary within the indicated grid region.



3. Right lower quadrant (RLQ): This quadrant contains parts of the small and large intestines, right ovary, right uterine (fallopian) tube, appendix, and right ureter.
