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