[edit] Borders

The boundaries are as follows:

	roof: pelvic brim[1]
posterior: sacrum, coccyx	lateral: obturator internus	anterior: pubic symphysis
	floor: pelvic floor

[edit] Greater and lesser pelvis

The lesser pelvis (or "true" pelvis" only includes structures inferior to the pelvic brim.

For example, the pelvic splanchnic nerves arising at S2-S4 is in the true pelvis, but the femoral nerve from L2-L4 is only in the "false pelvis", or greater pelvis.

[edit] Ligaments

Ligament	From	To
broad ligament of the uterus
* mesovarium	ovary
* mesosalpinx	Fallopian tube
