Final answer:
The Triquetral bone identification requires a provided diagram, which is not available. Osteocalcin is a hormone produced by bone cells; vertebrae do not make up part of the rib cage; the ossicles, cranium and ilium bones have different classifications in the skeleton; the parietal bone is part of the brain case. Option 3, C is correct.
Step-by-step explanation:
The Triquetral bone is one of the eight small carpal bones in the wrist. Without an accompanying diagram to reference arrow positions, it is not possible to definitively tell you which arrow (A, B, C, or D) points to the Triquetral bone. Correct identification requires visual confirmation. For the other questions provided, here are the answers:
True or False. Osteocalcin is a hormone produced by bone cells. - True.
True or False. Vertebrae make up part of the rib cage. - False. The vertebrae are part of the spinal column, whereas the rib cage is formed by the ribs and the sternum.
For each of the following bones, indicate whether they are part of the axial or appendicular skeleton:
A. The ossicles of the middle ear - Axial.
B. The femur - Appendicular.
C. The phalanges - Appendicular.
D. The bones of the cranium - Axial.
E. The ilium - Appendicular.
Lastly, the bone of the brain case referenced in the question is the parietal bone.
