Check all that are true statements regarding the differences between a typical female and male pelvis. - The female ileum does not project far above the sacroiliac joint. - The body of the pubis is longer in females than in males. - The greater sciatic notch is much narrower in females than in males. - The female coccyx projects vertically, while the male coccyx has a more posterior tilt.

Answer: - The female ileum does not project far above the sacroiliac joint. - The body of the pubis is longer in females than in males. To accommodate childbirth, females have wider hips than males, due to the ilium flaring more laterally. Because of this, the greater sciatic notch is also wider in females. The body of the pubis is longer in females than in males, and the coccyx has a more posterior tilt.

This figure shows the os coxae. Which of these statements about the figure is correct? -The figure shows a right bone, and number 1 indicates the anterior superior iliac spine. -The figure shows a left bone and number 7 indicates the obturator foramen. -The figure shows a right bone, and number 3 indicates the greater sciatic notch. -The figure shows a right bone, and number 8 indicates the ischial spine. -The figure shows a left bone, and number 6 indicates the ischial tuberosity.

Answer: - The figure shows a right bone, and number 3 indicates the greater sciatic notch.

Which is not correct regarding the femur? - The intercondylar fossa is located on the anterior surface of the bone. - The depression in the head of the femur is called the fovea. - The head of the femur articulates with the acetabulum. - The condyles are located at the distal end of the bone. - In anatomic position, the femur is angled medially.

Answer: The intercondylar fossa is located on the anterior surface of the bone.
