- Passage for Obturator and vessels
Compares to the Male Pelvis, the FEMALE Pelvis is:
- Thinner
- Lighter

- OVAL shaped Foramen
- LARGE Pelvic outlet
Ant. Sup. Iliac Spine
- Attachment of the Inguinal Ligament
- Proximal Attachments for Sartorius Muscle
The pelvic inlet is referred to as what?
Pelvic Brim
How many bones make up the Pelvis?
3
The Pelvic outlet is bounded by what?
- Coccyx
- Sacrotuberous Ligaments
- Ischial tuberosities
- Ischiopubic Rami
- Pubic Symphysis (bone)
Ant. Inf. Iliac Spine
Proximal attachment for straight head of RECTUS FEMORIS
Iliac Fossa
