Obturator canal
Iliac fossa
Acetabulum
Sacral hiatus
6. Which function best explains how the pelvic girdle contributes to standing and walking?
It transfers upper-body weight toward the lower limbs
It produces movement through contraction of pelvic bone
It prevents all motion between the trunk and lower limbs
It directly forms the knee joint
7. In standard adult anatomy, which bones form the pelvic girdle itself?
The sacrum and two femurs
The sacrum and coccyx only
The right and left hip bones
The lumbar vertebrae and sacrum
8. When a person sits upright on a firm surface, which pelvic landmarks bear much of the direct pressure?
Anterior superior iliac spines
Pubic tubercles
Ischial spines
Ischial tuberosities
9. At a sacroiliac joint, which paired articular regions meet?
The acetabulum and femoral head
The pubic bodies of the two hip bones

The auricular surfaces of the ilium and sacrum
10. Each adult hip bone develops through the fusion of which three bones?
Sacrum, coccyx, and ilium
Ilium, femur, and pubis
Ilium, ischium, and pubis
Ischium, sacrum, and femur
11. A fracture crosses the greater sciatic notch. Which part of the hip bone contains this landmark?
Pubis
Femur
Acetabular labrum
Ilium
12. Which statement correctly describes the bony formation of the acetabulum?
It is formed entirely by the ilium
It receives contributions from the ilium, ischium, and pubis
It is formed by the pubis and sacrum
It is a depression on the proximal femur
13. What structure joins the right and left hip bones at the front of the pelvis?
Sacral promontory
Acetabular labrum
Sacroiliac joint
Pubic symphysis

Ilium
Ischium
Pubis
Sacrum
15. Which joint provides the main bony connection between each hip bone and the axial skeleton?
Hip joint
Sacroiliac joint
Lumbosacral joint
Pubic symphysis
16. A student is asked to distinguish the pelvic girdle from the complete bony pelvis. Which statement is most accurate?
The pelvic girdle includes the femurs, while the bony pelvis does not
The bony pelvis includes the paired hip bones plus the sacrum and coccyx
The terms differ only because one refers to children and the other to adults
The pelvic girdle is the sacrum alone, while the bony pelvis is both hip bones
