Across
- 6. Muscles attached to the skeleton that enable movement through their contractions and relaxations.
- 9. Thin, flat bones that provide protection and surface area for muscle attachment, such as the skull and sternum.
- 11. Bones characterized by their elongated shape, such as the femur and humerus.
- 12. Muscles found in the walls of internal organs and blood vessels, responsible for involuntary movements.
- 13. Bones that are roughly equal in length and width, providing stability and support, such as the bones in the wrist and ankle.
- 14. Porous, less-dense inner bone tissue that contains bone marrow and helps with shock absorption.
- 15. A type of muscle contraction where the tension remains constant, but the length of the muscle changes.
- 17. A muscle that moves a body part away from the midline of the body or a specific reference point.
- 19. A muscle that moves a body part toward the midline of the body or a specific reference point.
- 22. Mature bone cells that maintain and monitor bone tissue.
- 23. Fibrous connective tissues that attach muscles to bones, enabling the transmission of force and facilitating movement.
- 24. The system of muscles that allows for movement, generates heat, and provides support to the body.
- 26. A strong, flexible connective tissue found at the ends of bones, in the nose, and in the ears, providing support and cushioning.
- 27. Bones that do not fit into the other categories due to their unique shapes, such as the vertebrae and facial bones.
Down
- 1. A muscle that increases the angle at a joint, moving two bones farther apart.
- 2. Hard, calcified connective tissue that forms the structural framework of the body and protects internal organs.
- 3. A muscle that opposes the action of the agonist and is responsible for returning the limb to its original position.
- 4. A type of muscle contraction where the length of the muscle remains constant, but tension is generated.
- 5. The system of bones, joints, and associated tissues that provide support, protection, and movement to the body.
- 7. A muscle that decreases the angle at a joint, bringing two bones closer together.
- 8. A muscle primarily responsible for producing a specific movement or action.
- 10. The decline in muscle performance due to the accumulation of metabolic byproducts, such as lactic acid, during prolonged exercise.
- 12. A muscle that assists the agonist in performing a movement by providing additional force or stability.
- 16. Tough bands of fibrous connective tissue that connect bones to other bones, providing stability and limiting excessive movement.
- 17. The portion of the skeletal system that includes the skull, vertebral column, and ribcage, providing support and protection for vital organs.
- 18. Muscles found in the walls of the heart, responsible for pumping blood and characterized by involuntary contractions.
- 19. The portion of the skeletal system that includes the limbs and their associated bones, allowing for movement and locomotion.
- 20. The points of articulation between two or more bones, allowing for movement and flexibility.
- 21. Dense, hard outer bone tissue that provides strength and support.
- 25. Muscles characterized by their striped appearance due to the arrangement of actin and myosin filaments, such as skeletal and cardiac muscles.
