In the development of the human embryo, the kidneys fail to ascend and usually remain at the brim of the pelvis.

I lifted the calf's lower jaw a' as the cow gave a heave I eased it over the brim of the pelvis.

When they can feel that the widest part of the baby's head has entered the brim of the pelvis, the baby's head is engaged.

It passes down along the brim of the pelvis and gives off two large branches - the "inferior epigastric artery" and a "deep circumflex artery."

I found in Subject B the greater sciatic notch to be wide and shallow and the ischial tuberosities to be everted, the ilia inclined to the vertical and the brim of the pelvis almost circular in outline.

She did a pretty fair job, too since a cow is a lot stronger than a man, but I kept my arm rigid against the calf and though each heave forced me back I maintained a steady pressure till I had pushed him to the brim of the pelvis.

The internal iliac vein (hypogastric vein) begins near the upper part of the greater sciatic foramen, passes upward behind and slightly medial to the Internal iliac artery and, at the brim of the pelvis, joins with the external iliac vein to form the common iliac vein.
