Final answer:
The statement regarding the Arthrex Clavicle Plating System being titanium is false. Osteocalcin is a hormone produced by bone cells, and vertebrae are part of the rib cage. Nails are primarily composed of keratin, and a broken bone is the same as a bone fracture. The statement is B. False
Step-by-step explanation:
The current plates and screws in the Arthrex Clavicle Plating System are not made of titanium; therefore, the statement is False. Osteocalcin is indeed a hormone produced by bone cells, so that statement is True. The vertebrae do make up part of the rib cage, so that statement is True. For the following bones: The ossicles of the middle ear - Axial skeleton, The femur - Appendicular skeleton, The phalanges - Appendicular skeleton, The bones of the cranium - Axial skeleton, The ilium - Appendicular skeleton.
Most bones are indeed made entirely of cartilage at birth, which makes that statement True. A broken bone is the same as a bone fracture, so that statement is also True. The nail bed does not refer to the middle portion of the hard nail plate, thus making that statement False. Nails are composed mainly of a protein called keratin, so the correct answer is C. Keratin. Therefore, the statement is B. False.
