Pelvic Cavity and Lesser Pelvis
The cavity defined by the pelvic girdle up to the pelvic brim is also known as the pelvic cavity. The region of the body defined by the pelvic girdle and the pelvic cavity is called the lesser pelvis (or true pelvis).
As the pelvis is concave, another cavity is defined by the pelvis above and in front of the pelvic brim. This is referred to this as the greater pelvis (or false pelvis). Some authors consider it part of the pelvic cavity, others consider it part of the abdominal cavity, others call both the abdominopelvic cavity.
