pu·bis(pyū'bis), [TA] The term pubis (short for os pubis 'bone of the pubes') is correctly applied to the pubic bone. However, the correct Latin word for 'the pubic region' is the singular noun pubes.
The anteroinferior portion of the hip bone, distinct at birth but later becoming fused with the ilium and ischium; it is composed of a body that articulates with its fellow at the symphysis pubis, and with two rami; the superior ramus enters into the formation of the acetabulum, and the inferior ramus fuses with the ramus of the ischium to form the ischiopubic ramus.
The pubic bone; the anteroinferior part of the hip bone. In the adult, it and the ilium and ischium form the pelvic bone. The superior and inferior rami unite medially to form the pubic symphysis; at its lateral end the pubic bone forms approx. one fifth of the acetabulum.
