Down
- 1. A delicate connective tissue layer
- 2. A muscle that stabilizes or fixes a part of the body to which a muscle in the process of moving another part is attached
- 3. Sites where the ends of motor nerve fibers connect to muscle fibers
- 5. A sheet-like, fibrous connective tissue that serves as an attachment point for muscles
- 6. Muscles that decrease the thoracic cavity size
- 7. The site that undergoes most of the movement when a muscle contracts
- 8. Part of skeletal muscle
- 9. Muscles that increase the size of the thoracic cavity when they contract
- 11. A muscle that helps another muscle perform a particular function effectively
- 13. A fibrous connective tissue that attaches muscle to bone
- 14. A sheath of fibrous elastic tissue surrounding a muscle
- 15. A muscle or muscle group that directly produces a desired movement
