4. the bones of the fingers and toes.
6. Either of two slender bones in humans that extend from the manubrium of the sternum to the acromion of the scapula. Also called collarbone.
7. One of a series of long curved bones occurring in 12 pairs in humans and extending from the spine to or toward the sternum.
8. A flat triangular bone located at the front of the knee joint. Also called kneecap.
11. The seven segments of the vertebral column located in the neck.
13. A bone between the lumbar vertebrae and tail vertebrae, composed of five fused vertebrae that form the posterior pelvic wall.
14. the inner and larger bone of the forearm, on the side opposite the thumb.
15. the skeleton of the head, consisting of the cranium and the mandible.
17. The quadrangular bone at the back of the tarsus. Also called heel bone.

1. The outer and narrower of two bones of the human lower leg, extending from the knee to the ankle.
2. The vertebrae associated with the chest and ribs in vertebrates
3. the bone of the upper arm, extending from shoulder to elbow.
5. The broad upper division of the sternum with which the clavicle and first two ribs articulate.
9. The smallest and lowest of the three divisions of the human sternum, which is cartilaginous in early life but usually ossifies by adulthood.
10. A bone of the leg situated between the pelvis and knee in humans. It is the largest and strongest bone in the body.
12. The vertebrae located between the lowest ribs and the pelvic girdle in all vertebrates.
15. A long flat bone in most vertebrates that is situated along the ventral midline of the thorax and articulates with the ribs.
16. A small triangular bone at the base of the spinal column in humans and other apes, consisting of several fused rudimentary vertebrae. Also called tailbone.
18. the flat triangular bone in the back of the shoulder; the "shoulder blade"
