The subpubic angle (or pubic angle) is the angle in the human body as the apex of the pubic arch, formed by the convergence of the inferior rami of the ischium and pubis on either side. The subpubic angle is important in forensic anthropology , in determining the sex of someone from skeletal remains.

It is divisible into three portions: the body, the superior ramus, and the inferior ramus. The body forms approximately one-third of the acetabulum.
from the ischium, the inferior ramus of the ischium; It forms the inferior border of the obturator foramen and serves as part of the origin for the obturator internus and externus muscles. Also, most adductors originate at the ischiopubic ramus. The fascia of Colles is on attached to its margin.
The ischial tuberosity (or tuberosity of the ischium, tuber ischiadicum), also known colloquially as the sit bones or sitz bones, [1] or as a pair the sitting bones, [2] is a large posterior bony protuberance on the superior ramus of the ischium. It marks the lateral boundary of the pelvic outlet.
Each crus begins proximally as a blunt-pointed process in anterior to the tuberosity of the ischium, along the perineal surface of the conjoined (ischiopubic) ramus. [citation needed] Just proximal to the convergence of the two crura, they come into contact with the bulb of (corpus cavernosum of) penis. [citation needed]
