Pelvic symphysis

The pelvic symphysis (Symphysis pelvina) unites the two coxal bones on the median line of the pelvic floor. Its structure varies according to the species, sometimes to the age.

In humans, the pelvic symphysis is very short, being exclusively pubic. It is much longer in domestic mammals and especially in ungulates: in these animals, it includes a pubic part (Symphysis pubica) and an ischial part (Symphysis ischiadica)."

Also in humans, the pelvic symphysis is a real symphysis or even a mixed joint, with a draft of a synovial joint, while in most domestic Mammals, it is a synchondrose that the age often transforms into a synostose.
