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 ...
In human anatomy, and in mammals in general, the mons pubis or pubic mound (also known simply as the mons / m ɒ n z /, and known specifically in females as the mons Venus or mons veneris) [1] [2] is a rounded mass of fatty tissue found over the pubic symphysis of the pubic bones.
The urogenital triangle is the area bound by a triangle with one vertex at the pubic symphysis and the two other vertices at the iliac tuberosities of the pelvic bone. Components [ edit ]
The pelvic brim is an approximately butterfly-shaped line passing through the prominence of the sacrum, the arcuate and pectineal lines, and the upper margin of the pubic symphysis. The pelvic brim is obtusely pointed in front, diverging on either side, and encroached upon behind by the projection forward of the promontory of the sacrum.
Medial to the pubic tubercle is the pubic crest, which extends from this process to the medial end of the pubic bone. It gives attachment to the conjoint tendon , the rectus abdominis , the abdominal external oblique muscle , and the pyramidalis muscle .
The linea terminalis or innominate line consists of the pubic crest, pectineal line (pecten pubis), the arcuate line, the sacral ala, and the sacral promontory. [1]It is the pelvic brim, which is the edge of the pelvic inlet.
Average measurement in female Anteroposterior or conjugate diameter or conjugata vera: Extends from the upper margin of the pubic symphysis to the sacrococcygeal joint; about 110 mm. Transverse diameter: Extends across the greatest width of the superior aperture, from the middle of the brim on one side to the same point on the opposite; about ...
The pelvis must be orientated such that the observer is looking at the dorsal aspect of the pubis and ischio-pubic ramus. Phenice describes the subpubic concavity as ‘a lateral recurve which occurs in the ischio-pubic ramus… a short distance below the lower margin of the pubic symphysis.’ This is also only found in female examples.
