General information about the structure of the hip bone, as well as the peculiarities of the structure of the ilium are discussed in the previous PDF note.
Let us examine the structure of the pubis (os pubis).
Pubis (os pubis)
body of the pubis (corpus ossis pubis)
superior pubic ramus (ramus superior ossis pubis)
Superior pubic ramus (ramus superior ossis pubis) 
inferior pubic ramus (ramus inferior ossis pubis)
There is a symphysial surface (facies symphysialis) to which the pubic symphysis is attached. It is located the border of the transition of the superior ramus to the inferior ramus on the medial side.
On the superior ramus of the pubis lies the pubic tubercle (tuberculum pubicum), which is connected to the iliopubic eminence (eminentia iliopubica)
by the pubic crest (crista pubica);
and then the pecten pubis (pecten ossis pubis).
Connecting with each other, the pubis and the ischium form the obturator foramen (foramen obturatum).
On the inferior pubis ramus, downward from this foramen, there is the obturator groove (sulcus obturatorius), in which the nerves and vessels pass.
There are tubercles on the sides of the obturator foramen on the pubis. These are the anterior obturator tubercle (tuberculum obturatorium anterius) and the posterior obturator tubercle (tuberculum obturatorium posterius).
