The pudendal nerve arises from the sacrum and leaves the pelvis through the greater sciatic foramen (opening through the bone). It then crosses the spine of the ischium and reenters the pelvis through the lesser sciatic foramen. It splits into two terminal branches as it approaches the urogenital diaphragm (which fills the space within the pubic arch).
