Question

Quizplus · Accepted Answer

The pelvic inlet (or pelvic brim) is formed by three bony landmarks: the sacral promontory (located on the anterior surface of the sacrum), the pubic crest (located on the superior border of the pubic bone), and the arcuate lines of the ilia (located on the inner surface of the iliac bone). The ischial tuberosities are not part of the pelvic inlet; they are located on the inferior part of the pelvic bone and contribute to the pelvic outlet.
