Across
- 6. Lever with the resistance between the fulcrum and the effort, as in the ankle during a calf raise
- 9. Synovial joint with the greatest range of motion, found at the hip and shoulder
- 13. Division of the skeleton made up of the skull, vertebral column, sternum, and ribs
- 15. Fixed pivot point of a lever system; in the body, the joint
- 16. Contraction in which muscle tension rises but muscle length does not change
- 20. Load or weight that a lever system must move or support
- 23. Synovial joint allowing flexion and extension in one plane only, as at the elbow
- 24. Most common lever in the body, with the effort between the fulcrum and the resistance, as at the elbow during a biceps curl
- 26. Force applied to a lever by the contracting muscle
- 27. Muscle that assists the prime mover and steadies the movement
- 30. Lever with the fulcrum between the effort and the resistance, as in the neck during head extension
- 32. Movement that decreases the angle between two bones at a joint
- 34. Fluid-filled sac that cushions areas where tendons or muscles pass over bone
- 35. Division of the skeleton made up of the limbs and the shoulder and pelvic girdles
- 39. Muscle that relaxes and lengthens to allow the prime mover to act
- 42. Muscle attachment on the bone that moves during contraction
- 43. Vertical axis running head to toe, around which rotation takes place
- 44. Rotation of the forearm that turns the palm to face forward or upward
- 45. Synovial joint with an oval head sitting in an elliptical socket, as at the wrist
Down
- 1. Rotation of the forearm that turns the palm to face backward or downward
- 2. Rigid bar that turns about a fixed point to move a load; in the body, a bone
- 3. Freely moveable joint type with a capsule, lubricating fluid, and articular cartilage
- 4. Movement that points the toes away from the shin
- 5. Turning of a bone around its own long axis, as at the shoulder or hip
- 7. Synovial joint shaped like a rider's seat, found at the base of the thumb
- 8. Synovial joint allowing rotation only, as between the first two vertebrae
- 10. Movement of a body part toward the midline of the body
- 11. Slightly moveable joint type in which bones are joined by cartilage, as between vertebrae
- 12. Movement that raises the top of the foot toward the shin
- 14. Movement of a body part away from the midline of the body
- 17. Muscle chiefly responsible for producing a movement; the prime mover
- 18. Contraction in which the muscle lengthens under tension while controlling a load
- 19. Muscle that stabilizes the origin so the prime mover can work efficiently
- 21. Plane dividing the body into upper and lower portions; rotation occurs in it
- 22. Wedge of fibrocartilage in the knee that improves fit and absorbs shock
- 25. Tough band of connective tissue joining bone to bone and stabilizing a joint
- 28. Cone-shaped movement combining flexion, abduction, extension, and adduction
- 29. Connective tissue that attaches muscle to bone and transmits contraction force
- 31. Plane dividing the body into left and right; flexion and extension occur in it
- 33. Contraction in which the muscle shortens while producing force
- 36. Movement that increases the angle between two bones at a joint
- 37. Plane dividing the body into front and back; abduction and adduction occur in it
- 38. Smooth tissue covering the ends of bones that reduces friction in a joint
- 40. Immoveable joint type in which bones are held by dense connective tissue, as in the skull
- 41. Muscle attachment on the bone that stays relatively still during contraction
