Across
  1. 2. / the muscle that stabilises the joint. Keeps it still. For a bicep curl, this would be the deltoid.
  2. 8. / movement towards the midline of the body.
  3. 10. / where the muscle is moving whilst contracting.
  4. 15. / a nerve cell which conducts a nerve impulse to a group of muscle fibres.
  5. 18. / Where the muscle lengthens & contracts.
  6. 21. / Positive electrical charge inside the nerve and muscle cells which conducts the nerve impulse down the neuron and into the muscle fibre.
  7. 24. / Limbs that create movement
  8. 25. / This where the muscle shortens & contracts.
  9. 26. / an area of the body where two or more bones articulate to create human movement
  10. 27. muscle responsible for the movement at a joint.
  11. 29. / muscle that has an action opposite to the agonist.
  12. 30. / where the muscle length remains the same whilst contracting.
Down
  1. 1. / a tough band of fibrous, slightly elastic connective tissue that attaches bone to bone
  2. 3. / body part moves in a forwards direction. Decreasing an angle at a joint.
  3. 4. / unique to the ankle. Toes pointed towards ground.
  4. 5. / body part moves in a backwards direction. Increasing an angle at a joint.
  5. 6. / unique to the ankle. Foot moves towards the shin.
  6. 7. Rotation / when the bone turns about its long axis towards the body.
  7. 9. / pain and stiffness felt in the muscle which peaks 24-72hours after exercise, associated with eccentric muscle contrations
  8. 11. / movement away from the midline of the body.
  9. 12. Rotation / when the bone turns about its long axis away from the body
  10. 13. / a motor neuron & the muscle fibres it stimulates.
  11. 14. / shoulder moves away from mid line of body.
  12. 16. / A chemical (Ach)produced and secreted by a neuron which transmits the nerve impulse across the synaptic cleft to the muscle fibre.
  13. 17. / Bones that serve to protect – cranium, spine, ribs
  14. 19. / Shoulder moves towards mid line of body.
  15. 20. / smooth tissue which covers the surface of articulating bones to absorb shock and allow friction-free movement
  16. 21. / Depending on whether the stimulus is above a threshold, all muscle fibres will give a complete contraction or no contraction at all
  17. 22. of movement / the description of 3 dimensional movement at a joint
  18. 23. / where a circular motion can be described. Mainly at shoulder joint.
  19. 28. / fibrous connective tissue that attaches muscle to bone
