What is the pelvic girdle composed of?
- Right & Left pelvic bones (Coxal, Innominate or hip bones)
- Sacrum
- Coccyx
What forms the pelvic bones?

What is the lower limb divided into on the basis of major joints, components, and superficial landmarks?
Gluteal region
Thigh
Leg
Foot
Attachment point of lower limb to the bodies trunk in axial skeleton
Pelvic Girdle
Where do 2 hip bones articulate with each other?
Anteriorly at the pubic symphysis
Where does the sacrum articulate?
Two pelvic bones posteriorly at the sacro-iliac joints
Bones that apart of the axial skeleton
Sacrum and Coccyx
Bones of the apendicular skeleton
Pelvic bones
Circular opening between the abdominal abdominal cavity and pelvic cavity through which structures travel between abdomen and pelvis
Pelvic brim
Protrudes into inlet forming posterior margin in inlet
Promontory of the sacrum
Follow the pelvic brim
Promontory of the sacrum -> ala of sacrum –> linae terminalis (arcuate line, pectan pubis, pectaneal line) in the pubic crest to the pubic symphysis
What lines the same vertical plane in the pelvis?
- Front edge of the top of the pubic symphysis
- Anterior superior iliac spine
Space above pelvic inlet including the lower portion of the abdomen that lies between the flaired illiac crests
Greater/ False Pelvis
Space below the pelic inlet containing the pelvic viscera
Lesser/ True Pelvis
What are the Ilium, Ischium and pubis attached by at birth?
Cartilage at the acetabelum
What forms the hip joint?
Acetabulum & Head of the femur
