Distinguish among the abdominopelvic regions of the body

Key Points

The abdominopelvic cavity tin exist subdivided into four quadrants and nine areas.
The quadrants are labeled by location: the right upper, correct lower, left upper, and left lower quadrants.
The nine regions are smaller than the four abdominopelvic quadrants and include the correct 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 10th division.
The purpose of the intestinal divisions is to describe regional anatomy in the abdomen, and to help clinicians determine which organ and tissues are involved in a disease based on which regions experience pain.

Key Terms

left upper quadrant: The left upper quadrant is the location of the left portion of the liver, the larger portion of the stomach, the pancreas, left kidney, spleen, portions of the transverse and descending colon, and parts of the small intestine.
Correct upper quadrant: The right upper quadrant contains the correct portion of the liver, gallbladder, right kidney, a small portion of the breadbasket, portions of the ascending and transverse colon, and parts of the small-scale intestine.
left lower quadrant: The left lower quadrant houses the majority of the small intestine, some of the large intestine, the left female reproductive organs, and the left ureter.
nine divisions: An alternate system for dividing the abdominopelvic cavity into regions.
correct lower quadrant: In the right lower quadrant sits the cecum, appendix, part of the small intestines, the right female reproductive organs, and the right ureter.

Anatomists and medical personnel separate the abdominopelvic cavity into smaller regions to facilitate report and discussion. These divisions are oft used to categorize the private abdominal organs by their location and office and are used past clinicians to assist diagnose the source of abdominal pain and determine advisable treatment. The most common divisions for the abdominopelvic region are the four quadrants and ix regions.

This image illustrates the organs included in the four quadrants and nine regions as described above.

Abdominal nine divisions (a) and quadrant regions (b): The abdomen is subdivided into four quadrants and nine areas.

Intestinal Four Quadrants

The abdominopelvic region tin be divided into four quadrants. These quadrants are defined past the intersection of the sagittal plane with the umbilical plane (the transverse airplane through the navel). Clinicians utilize these regions to determine the organs and tissues that may exist causing hurting or discomfort in that region.

Right Upper Quadrant

The right upper quadrant contains the correct portion of the liver, the gallbladder, right kidney, a small portion of the stomach, the duodenum, the head of the pancreas, portions of the ascending and transverse colon, and parts of pocket-sized intestine. Pain in this region is associated with infection and inflammation in the gallbladder and liver or peptic ulcers in the tum.

Left Upper Quadrant

The left upper quadrant is the location of the left portion of the liver, function of the stomach, the pancreas, left kidney, spleen, portions of the transverse and descending colon, and parts of the small intestine. Pain in this region is associated with malrotation of the intestine and colon.

Right Lower Quadrant

In the right lower quadrant sits the cecum, appendix, part of the small-scale intestines, the right half of the female reproductive system, and the correct ureter. Hurting in this region is most commonly associated with appendicitis.

Left Lower Quadrant

The left lower quadrant houses the bulk of the modest intestine, some of the large intestine, the left half of the female person reproductive system, and the left ureter. Pain in this region is by and large associated with colitis (inflammation of the large intestine) as well as pelvic inflammatory disease and ovarian cysts in females.

Abdominal Nine Divisions

The nine divisions of the abdominopelvic region are smaller than the iv quadrants, allowing for a more than detailed discussion. These divisions are marked by two parasagittal and two transverse planes centered effectually the navel. Most organs are part of multiple regions, including the gallbladder, duodenum, stomach, kidneys, spleen, small intestine and colon. The perineum (the area beneath the hypogastric region at the bottom of the pelvic cavity) is sometimes considered to be a tenth partition in this arrangement.

Right Hypochondriac

The correct hypochondriac region contains the right portion of the liver, the gallbladder, the right kidney, and parts of the small intestine.

Left Hypochondriac

The left hypochondriac region contains function of the spleen, the left kidney, part of the stomach, the pancreas, and parts of the colon.

Epigastric

The epigastric (in a higher place stomach) region contains the majority of the stomach, part of the liver, role of the pancreas, role of the duodenum, role of the spleen, and the adrenal glands. This region pushes out when the diaphragm contracts during breathing.

Correct Lumbar

The correct lumbar region consists of the gallbladder, the correct kidney, part of the liver, and the ascending colon.

Left Lumbar

The left lumbar region consists of the descending colon, the left kidney, and function of the spleen.

Umbilical

The umbilical region contains the umbilicus (navel), and many parts of the small intestine, such every bit part of the duodenum, the jejunum, and the illeum. Information technology as well contains the transverse colon (the section between the ascending and descending colons) and the bottom portions of both the left and correct kidney.

Right Iliac

The right iliac region contains the appendix, cecum, and the right iliac fossa. It is also usually referred to equally the correct inguinal region. Pain in this expanse is by and large associated with appendicitis.

Left Iliac

The left illiac region contains part of the descending colon, the sigmoid colon, and the left illiac fossa. It is also commonly called the left inguinal region.

Hypogastric

The hypogastric region (below the breadbasket) contains the organs effectually the pubic bone. These include bladder, part of the sigmoid colon, the anus, and many organs of the reproductive arrangement, such as the uterus and ovaries in females and the prostate in males.
