Pelvis - Definition

Ask a question


The pelvis is the part of the skeleton operating the junction between the spinal column (mobile) and the lower limbs, by means of the coxofemoral and hip joints. In the shape of a funnel, it is constituted of the two left and right coxal bones, the coccyx, and the sacrum at the back. The two coxal bones, coming to a joint with the sacrum, form the pelvic girdle. The human pelvis is different from those of other hominids, due to our bipedalism. This especially has consequences on the anatomical conditions of childbirth.
