  1. ´╗┐Modified endoplasmic reticulum in muscle that concentrates and stores Ca2+.
    Sarcoplasmic Reticulum
  2. Intracellular second messenger that binds Ca2+.
    Calmodulin
  3. Enzyme that phosphorylates light protein chains of myosin in smooth muscle.
    Myosin Light Chain Kinase (MLCK)
  4. An enzyme that catalyzes the hydrolysis of ATP to ADP; releases energy used in the cell.
    ATPase
  5. A globular protein (G-actin) that polymerizes to form thin filaments (F-actin).
    Actin
  6. Forms thick filaments of the myofibril that convert chemical bond energy of ATP into motion.
    Myosin
  7. Enzyme that dephosphorylates light protein chains of myosin in smooth muscle.
    Myosin Phosphatase
  8. A single contraction/relaxation cycle in a muscle fiber.
    Twitch
  9. A graphic representation of muscular contractions.
    Myogram
  10. Creation of tension in muscle; active process that requires ATP.
    Contraction
  11. Delay between the muscle action potential and beginning of muscle tension that represents the time required for Ca2+ release and binding to troponin.
    Latent Period
  12. Release of tension created by contraction.
    Relaxation
  13. The amount of time it takes to become ready for a second contraction.
    Refractory Period
  14. Strength by which a muscle will give a complete response otherwise there is no response at all.
    All or none response
  15. Sustained muscle contraction.
    Tetanus
