Borders

The boundaries are as follows:

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

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.

v • d • e Bones of pelvis / pelvic cavity

General	sacrum, coccyx, hip bone

Ilium	body (arcuate line) wing: gluteal lines (posterior, anterior, inferior) – fossa – iliac spines (anterior superior, anterior inferior, posterior superior, posterior inferior) – crest – tuberosity

Ischium	body (ischial spine, lesser sciatic notch) – superior ramus (tuberosity of the ischium) – inferior ramus

Pubis	body – superior ramus (pubic tubercle, pubic crest, obturator crest) – inferior ramus (pectineal line)

Compound	acetabulum (acetabular notch) – iliopubic eminence / iliopectineal line – linea terminalis – ischiopubic ramus / pubic arch obturator foramen – greater sciatic foramen / greater sciatic notch – lesser sciatic foramen lesser pelvis (pelvic inlet, pelvic brim, pelvic outlet) – greater pelvis
