- 6. attaches to bones or skin
- 9. responsible for the striations; come in a dark and light form
- 10. provides the "go" signal for contraction and is stored in the SR
- 11. chains of contractile units made up of myofibrils

- 14. wraps a bundle of fasicles
- 16. means having many nuclei per cell
- 18. means "around"
- 19. means "striped"
