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.

Famous quotes containing the word lesser:
“It is not contrary to reason to prefer the destruction of the whole world to the scratching of my finger. It is not contrary to reason for me to choose my total ruin, to prevent the least uneasiness of an Indian, or person wholly unknown to me. It is as little contrary to reason to prefer even my own acknowledged lesser good to my greater, and have a more ardent affection for the former than the latter.”
—David Hume (1711–1776)
