The Skeletal System

1. the skeleton of the head, consisting of the cranium and the mandible.
3. The broad upper division of the sternum with which the clavicle and first two ribs articulate.
4. a large flat bone formed by the fusion of the ilium, ischium, and pubis.
5. A bone of the leg situated between the pelvis and knee in humans. It is the largest and strongest bone in the body.
8. the bone of the upper arm, extending from shoulder to elbow.
10. One of a series of long curved bones occurring in 12 pairs in humans and extending from the spine to or toward the sternum.
12. The seven segments of the vertebral column located in the neck.
13. 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.
14. A bone between the lumbar vertebrae and tail vertebrae, composed of five fused vertebrae that form the posterior pelvic wall.
15. The outer and narrower of two bones of the human lower leg, extending from the knee to the ankle.
16. the bones of the fingers and toes.
18. Either of two slender bones in humans that extend from the manubrium of the sternum to the acromion of the scapula. Also called collarbone.
19. A flat triangular bone located at the front of the knee joint. Also called kneecap.
20. the flat triangular bone in the back of the shoulder; the "shoulder blade"

2. The vertebrae located between the lowest ribs and the pelvic girdle in all vertebrates.
6. The quadrangular bone at the back of the tarsus. Also called heel bone.
7. The vertebrae associated with the chest and ribs in vertebrates
9. A long flat bone in most vertebrates that is situated along the ventral midline of the thorax and articulates with the ribs.
11. The smallest and lowest of the three divisions of the human sternum, which is cartilaginous in early life but usually ossifies by adulthood.
17. the inner and larger bone of the forearm, on the side opposite the thumb.
