Pelvic girdle connects hind limb with:
Correct answer: B. Hip bone
- A. Scapula
- B. Hip bone
- C. Sacrum
- D. Coccyx
Explanation
Option A: The scapula is the shoulder blade, which is part of the pectoral girdle. The pectoral girdle connects the upper limb with the axial skeleton. The pelvic girdle does not connect to the scapula. Option B: The hip bone is the part of the pelvic girdle that articulates with the femur, the thighbone. The hip bone is the only bone that connects the pelvic girdle to the hind limb. Option C: The sacrum is a triangular bone that is located at the base of the spine. It is made up of five fused vertebrae. The sacrum articulates with the hip bones at the sacroiliac joints. However, the sacrum is not part of the hind limb. Option D: The coccyx is a small, triangular bone that is located at the end of the spine. It is made up of four fused vertebrae. The coccyx articulates with the sacrum at the sacrococcygeal joint. However, the coccyx is not part of the hind limb.

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
