The pubic arch, also referred to as the ischiopubic arch, is part of the pelvis. It is formed by the convergence of the inferior rami of the ischium and pubis on either side, below the pubic symphysis. The angle at which they converge is known as the subpubic angle.
|Anatomical terms of bone|
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. A subpubic angle of 50-82 degrees indicates a male; an angle of 90 degrees indicates a female. Other sources operate with 50-60 degrees for males and 70-90 degrees in females. Women have wider hips, and thus a greater subpubic angle, in order to allow for child birth.
