iliofemoral is in front and strong.
Behind are the 2 weaker pubofemoral and ischiofemoral.

innervation of hip joint?
articular branches of Obturator and Femoral.
origins and insertions of obturator internus and piriformis? how do they leave pelvis
OI: origin is obturator membrane, insertiion is greater trochanter of femur. leaves through LSF
P: origin is 3 middle sacral bodies, insertion is also greater trochanter. leaves through GSF
where does the sacral plexus sit?
on piriformis
major supportive ligaments of uterus?
lateral cervical, utero-sacral and pubo-cervical
what is significant about the superior rectal and ovarian artery
