The Skeletal System
Across
- 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"
Down
- 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.
