Across
  1. 3. The law that an individual muscle fibre can either contract or relax and is unable to vary the force produced during each contraction
  2. 6. When a muscle develops tension in order to generate a force
  3. 7. An electrical signal that propagates down a neurone
  4. 10. A type of muscle fibre that is associated with fast contraction and high force
  5. 11. When a muscle works with another muscle to aid movement
  6. 14. A type of muscle fibre that is associated with fast contraction and medium force
  7. 15. A muscle that works alongside an agonist to stabilise movement
Down
  1. 1. A type of isotonic muscle contraction that causes the muscle to lengthen as it develops tension
  2. 2. A type of muscle fibre that is associated with slow contraction and low force
  3. 3. This muscle relaxes to oppose the movement of the agonist muscle
  4. 4. When a muscle becomes tired from continual contractions
  5. 5. A type of isotonic muscle contraction that causes the muscle to shorten in length as it develops tension
  6. 8. A type of muscle contraction where the muscle maintains its length as it develops tension
  7. 9. A type of specialised cell that transmits electrical signals
  8. 12. A type of muscle that causes movement by contracting; also known as a prime mover
  9. 13. A muscle that works alongside an agonist to assist movement
