Pelvis

The pelvis is the part of the skeleton that connects the spine to the lower limbs and surrounds the pelvic cavity.

The pelvis supports the body’s weight, protects pelvic organs, and provides attachment points for muscles and ligaments. In childbirth, the dimensions and shape of the maternal bony pelvis influence the space through which the fetus passes during vaginal birth.

The pelvis also contains or supports structures of the reproductive, urinary, and digestive systems.

QUICK FACT

The bony pelvis is only one part of the passage involved in childbirth; soft tissues and the position and size of the fetus also influence how the fetus passes through the birth canal.
