Aus Dornheim Anatomy
The rectum as the upper part of the rectum is about 15-16 centimeters long and is located in the small pelvis. Here it extends from the upper edge of the S3 to the perineum (lat. peritoneum). A lateral view shows that the structure of the rectum runs in two curves:
The flexura sacralis lies retroperitoneally and nestles against the concave shape of the sacrum (lat. Os sacrum). The flexura perinealis is already extraperitoneal.
