Pelvic girdle

• Also known as the Pelvis• Functions• Support, attachment points, and protect

organs

• Pelvis is divided into 2 parts• Os Coxa• Ilium• Largest, most superior portion of the Os Coxa

• Ischium• Inferior portion of the Os Coxa

• Pubis• Most anterior portion of the Os Coxa

• Acetabulum • Portion of the Os Coxa that articulates with

the head of the Femur
