pelvis, also called bony pelvis or pelvic girdle, in human anatomy, basin-shaped complex of bones that connects the trunk and the legs, supports The two pelvic bones are connected anteriorly by the pubic symphysis, while posteriorly they articulate with the pelvic spine to form the sacroiliac joints. The pelvis plays several important functions in the human body. The joints of the pelvis include the sacrococcygeal, lumbosacral, pubic symphysis, and the sacroiliac. The pelvic girdle is a ring-like bony structure, located in the lower part of the trunk. It connects the axial skeleton to the lower limbs. The pelvic joints are also held together by various ligaments which include the sacrotuberous, sacrospinous, and iliolumbar
