2. Match the bone names of Pelvic Girdle. Write down the correct letter in empty column. (Column A: Point where the coxal bones join anteriorly, Deep socket in the coxal bone that receives the head of the thigh bone, Joint between axial skeleton and pelvic girdle, Longest, strongest bone in body, Thin lateral leg bone, Heavy medial leg bone, Kneecap, Ankle bones, Bones forming the instep of the foot, Opening in hip bone formed by the pubic & ischial rami. Column B: a. Sacroiliac joints, b. Obturator foramen, c. Fibula, d. Pubic symphysis, e. Meta tarsal, f. Acetabulum, g. Tibia, h. Femur, i. Tarsal, j. Patella) 3. Compare the pectoral and pelvic girdles by choosing appropriate descriptive terms from the key. (Key: a. Flexibility most important, b. Massive, c. Lightweight, d. Insecure axial and limb attachment, e. Secure axial and limb attachment, f. Weight-bearing most important)

Answer

For part 2: 1. Point where the coxal bones join anteriorly is the (d) Pubic symphysis. 2. Deep socket in the coxal bone that receives the head of the thigh bone is the (f) Acetabulum. 3. Joint between axial skeleton and pelvic girdle is the (a) Sacroiliac joints. 4. Longest, strongest bone in the body is the (h) Femur. 5. Thin lateral leg bone is the (c) Fibula. 6. Heavy medial leg bone is the (g) Tibia. 7. Kneecap is the (j) Patella. 8. Ankle bones are (i) Tarsals. 9. Bones forming the instep of the foot are (e) Metatarsals. 10. Opening in hip bone formed by the pubic and ischial rami is the (b) Obturator foramen. For part 3: Pectoral girdle characteristics: (a) Flexibility most important, (c) Lightweight, and (d) Insecure axial and limb attachment. This is because the pectoral girdle (shoulder) is designed for range of motion. Pelvic girdle characteristics: (b) Massive, (e) Secure axial and limb attachment, and (f) Weight-bearing most important. This is because the pelvic girdle must support the body's weight and provide stability for movement.
