Study Notes
Abdominopelvic Cavity
- Divided into two main cavities: abdominal and pelvic.
- Abdominal Cavity:
- Houses stomach, spleen, liver, gallbladder, small intestine, and most of the large intestine.
- Surrounded by the peritoneum, a serous membrane.
- Pelvic Cavity:
- Contains the urinary bladder, parts of the large intestine, and reproductive organs.
Abdominopelvic Quadrants and Regions
- Two methods to divide the abdominopelvic cavity:
- Nine Regions: More commonly used in anatomical studies.
- Quadrants: Simplified method for clinicians to locate issues like pain or tumors.
- Quadrants are defined by a median and transverse plane intersecting at the umbilicus.
Abdominopelvic Regions
- Key Horizontal Lines:
- Subcostal Plane: Located at the lowest level of the 10th costal cartilages, corresponds to L3 vertebra posteriorly.
- Transtubercular Plane: Passes across the superior margins of the iliac crests.
- Key Vertical Lines:
- Midclavicular Lines: Drawn through the midpoints of the clavicles, medial to the nipples.
Named Regions of the Abdominopelvic Cavity
- Right Hypochondriac Region: Includes part of the stomach, liver, pancreas, and adrenal glands.
- Epigastric Region: Contains part of the stomach.
- Left Hypochondriac Region: Houses spleen, left colic flexure, and part of the pancreas.
- Right Lumbar Region: Includes the ascending colon and right colic flexure.
- Umbilical Region: Contains parts of the small intestine and transverse colon.
- Left Lumbar Region: Houses descending colon and a part of the left kidney.
- Right Iliac Region: Includes cecum and appendix.
- Hypogastric Region: Contains urinary bladder, sigmoid colon, and female reproductive organs.
- Left Iliac Region: Houses parts of the colon and small intestine.
Additional Information
- The nine regions provide precise anatomical references for organs.
- Quadrants are typically utilized in clinical settings to assess and describe symptoms or abnormalities.
