(Lesser pelvis , pelvic canal)

 

This is the pelvis below the pelvic brim, i.e. below the lineae terminales and sacral promontory. It is also called true pelvis or lesser pelvis. It contains pelvic viscera and has the parietal peritoneum covering the superior aspects of the pelvic viscera and dipping in between the viscera to form pouches. The main pelvic cavity covered by parietal peritoneum is a peritoneal pouch.

The pelvic cavity is further divided into three subcavities

bullet Inlet: The pelvic brim or superior aperture of lesser pelvis
bullet Midcavity at the level of the ischial spines
