Across
  1. 3. Connective tissue around individual muscle fibers (around individual muscle fibers within the fascile)
  2. 4. A muscle that directly produces a desired movement (performs the movement)
  3. 5. Peri-
  4. 7. Endo-
  5. 9. further away from the trunk
  6. 13. Toward the trunk or near the point of origin
  7. 16. Junction where motor neuron axon meets muscle fibers
  8. 19. Distal moveable end of a muscle
  9. 20. Connective tissue around a bundle of muscle fibers (between muscle fibers)
  10. 21. Directly opposes the movement of the agonist muscle
Down
  1. 1. Dense CT sheet covering a hole muscle; delineates muscle from each other and other adjacent tissues (muscle definition and separation)
  2. 2. Tiny parallel fibers that are multi nucleated
  3. 6. Composed of actin and myosin; hundreds run together lengthwise to form a muscle fiber
  4. 8. Small bundles of skeletal muscle fibers within a specific muscle
  5. 10. contains bundles of proteins (myosin and actin)
  6. 11. Fixed proximal end of a muscle
  7. 12. Closes (angulates a joint)
  8. 14. Thin, translucent membrane that surrounds each myofibril and is the location of nervous system interaction that allows for contraction and relaxation
  9. 15. Actin and myosin; contractile proteins that contribute to muscle contraction
  10. 17. Opens (straightens a joint)
  11. 18. Individual muscle cell (has a threadlike appearance)
