- 2. Strong connective tissue that supports the body and is softer and more flexible than bone.
- 3. Group of organs that work together to perform a specific function.
- 7. A muscle that is connected to the skeleton to form part of the mechanical system that moves the limbs and other parts of the body.
- 10. 206 bones that give our bodies structure and protects major organs.
- 14. Attaches bone to bone.
- 15. Attaches muscle to bone.
- 17. Tissue, largely fat, that lies directly under the dermis and serves as an insulator of the body and anchors the skin to under lying tissue of the body.
- 20. Involuntary muscle found in internal organs.

- 13. Body tissue that carries electrical messages back and forth between the bran and every other part of the body.
- 16. Dense fibrous membrane covering the surface of bones (except at their extremities) and serving as an attachment for tendons and muscles.
- 18. Dense, hard layers of bone tissue that lie underneath the periosteum.
