The subpubic angle is the angle formed by the convergence of the two rami of the pubic bone. It is an important anatomical landmark in the pelvis, used in determining the sex of a human skeleton and in obstetrics. However, there are several synonyms for this term that may be used interchangeably in scientific literature. These synonyms include the pubic angle, pubic arch, pubic symphysis angle, pubic diastasis angle, ischiopubic angle, and subpubic concavity. Knowing these synonyms can help researchers and medical professionals better communicate and understand anatomical structures and functions.
