Above: the size of the neonatal skull relative to that of the female pelvis (using real specimens). Both halves of the pelvis are joined anteriorly at the pubic symphisis, a fibrocartilaginous (a mixture of fibrous tissue and cartilaginous tissues) joint that keeps the pelvis steady. During pregnancy, the symphysis pubis widens an average of 2-3 mm from the usual 4-5mm gap. The average gap is about 7.7mm. This widening of the pelvic ring helps facilitate the delivery of baby.2
