The human abdomen is divided into quadrants and regions by anatomists and physicians for the purposes of study, diagnosis, and treatment. [1] [2] The division into four quadrants allows the localisation of pain and tenderness, scars, lumps, and other items of interest, narrowing in on which organs and tissues may be involved.
The abdominopelvic cavity is a body cavity that consists of the abdominal cavity and the pelvic cavity. [1] The upper portion is the abdominal cavity, and it contains the stomach , liver , pancreas , spleen , gallbladder , kidneys , small intestine , and most of the large intestine.
The peritoneum, by virtue of its connection to the two (parietal and visceral) portions, gives support to the abdominal organs. The peritoneum divides the cavity into numerous compartments. One of these the lesser sac is located behind the stomach and joins into the greater sac via the foramen of Winslow . [ 1 ]
The abdomen can be divided into quadrants or regions to describe the location of an organ or structure. Classically, quadrants are described as the left upper, left lower, right upper, and right lower. [citation needed] Quadrants are also often used in describing the site of an abdominal pain. [15] The abdomen can also be divided into nine regions.
The directional terms refer to the model's right and left, not the viewer's. Clinicians use the quadrant method because in reality, organs are mobile and move around when the patient is in different positions. The second method for dividing the abdominopelvic cavity is preferred by anatomists. This method divides the cavity into nine regions.
Gross anatomy - systemic or region-wise study of human body parts and organs. Gross anatomy encompasses cadaveric anatomy and osteology. Comparative anatomy - the study of evolution of species through similarities and differences in their anatomy. Microscopic anatomy . Cell biology and cytogenetics. Surface anatomy.
Organs formed inside the coelom can freely move, grow, and develop independently of the body wall while fluid in the peritoneum cushions and protects them from shocks. Arthropods and most molluscs have a reduced (but still true) coelom, the hemocoel (of an open circulatory system ) and the smaller gonocoel (a cavity that contains the gonads ).
Some sources consider this region part of the pelvic cavity, [citation needed] while others reframe the classification by calling the combination the abdominopelvic cavity. The greater pelvis supports the intestines (specifically, the ileum and sigmoid colon ), and transmits part of their weight to the anterior wall of the abdomen .
