The region of the pelvis below the pelvic brim is known as which?

Explanation:
Dividing the pelvis at the pelvic brim creates two regions: above the brim is the false (greater) pelvis, and below it lies the true (lesser) pelvis. The region below the pelvic brim is the true pelvis, which forms the main pelvic cavity containing the pelvic organs. The perineum lies outside this cavity, below the pelvic floor, and the abdomen is located above the brim. Therefore, the region below the pelvic brim is the true pelvis.
