Anatomy

3. The last bone at the bottom of your spine
5. The "shoulder blade"
6. each of a series of slender curved bones articulated in pairs to the spine (twelve pairs in humans), protecting the thoracic cavity and its organs.
7. a pair of organs that are found on either side of the spine, just below the rib cage in the back
8. any of the pieces of hard whitish tissue making up the skeleton in humans and other vertebrates.
9. the primary organs of the respiratory system
11. The bones in your fingers and toes
17. a strong, fibrous tissue that connects bones to other bones, providing stability and support to joints
18. the large bony frame near the base of the spine to which the hindlimbs or legs are attached in humans and many other vertebrates.

1. either of the pair of bones joining the breastbone to the shoulder blades.
2. each of the series of small bones forming the backbone, having several projections for articulation and muscle attachment, and a hole through which the spinal cord passes.
4. each of the upper and lower bony structures in vertebrates forming the framework of the mouth and containing the teeth.
5. an internal or external framework of bone, cartilage, or other rigid material supporting or containing the body of an animal or plant.
10. a bone framework enclosing the brain of a vertebrate; the skeleton of a person's or animal's head
12. A muscular organ that pumps blood
13. any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body
14. a series of vertebrae extending from the skull to the small of the back, enclosing the spinal cord and providing support for the thorax and abdomen; the backbone.
15. the bone of the upper arm or forelimb, forming joints at the shoulder and the elbow.
16. a whitish fibre or bundle of fibres in the body that transmits impulses of sensation to the brain or spinal cord, and impulses from these to the muscles and organs.
