Posterior pelvis anatomy. A distinction is made between the lesser or true pelvis inferior to the terminal line and the greater or false pelvis above it. Ilium ischium and pubis ilium prominences asis. Posterior pelvic tilt is a backward and upward rotation of the pelvic bone.

It is formed by its anatomical borders. These muscles are important for the stabilization of the pelvis during constant mechanical stress that it suffers. The muscle originates from the body of the pubis and attaches to the pectineal line and proximal part of the linea aspera of femur.

Located between the thighs it acts as the inferior outlet of the pelvis. The pelvic brim is defined by a line formed by the upper margin of the pubic symphysis anteriorly and the pectineal line of the pubis the arcuate line of the ilium and the sacral promontory the anterior margin of the superior sacrum posteriorly. It is enervated by the obturator nerve.

Ivc is formed by the union of the 2 common iliac veins just to the right of l5. The bony pelvis pelvic skeleton is the part of the skeleton embedded in the pelvic region of the trunk. As it ascends the ivc remains to the right of the aorta.
