The pubic bone (os pubis) has an enlarged part - the body, and two branches. The body of the pubic bone (corpus ossis pubis) forms the anterior section of the acetabulum. From the front comes the upper branch of the pubic bone (ramussuperior ossis pubis) with the ilium-pubic elevation (eminentia iliopubica), located along the fusion of the pubic bone with the iliac.
The anterior part of the upper branch sharply curves downwards and passes into the lower branch of the pubic bone (rarnus inferior ossis pubis). In the area of the medial edge of the pubic bone is an oval shaped symphysial surface (facies symphysialis), serving to connect with the pubic bone of the opposite side. On the upper branch of the pubic bone, near its medial end, there is a pubic tubercle (tuberculum pubicum). On the back surface of the lower branch of the pubic bone in the direction from the rear in the front and medially there is a locking groove (sulcus obturatorius), to which the vessels of the same name and nerve adhere.
