  1. Actin
    Fibrous motor protein composed of two spiral chains that is associated with I band and is involved in muscle contraction
  2. Anaerobic
    Condition where no oxygen is present
  3. ATP
    Molecule involved in metabolic short?term energy storage that cells use to store energy. The molecule contains three phosphates
  4. Cardiac muscle Muscle under involuntary control that contains striations and is only found in the heart
  5. Contractile protein
    Protein that have the ability to contract when stimulated and include actin and myosin
  6. Creatine phosphate
    Organic compound found in muscles of vertibrates that serves as short term energy for muscle contraction
  7. Endomysium
    Connective tissue that surrounds single muscle fiber and contains capillaries that feed the muscle fiber and nerve fiber that control the muscle fiber
  8. Epimysium
    Dense irregular connective tissue that surrounds entire muscle and separates the muscle from surrounding tissue
  9. Fascicle
    Bundle of muscle fibers that contain between 10 to 100 fibers or cells
  10. Glucose
    Six carbon single sugar and is the most common dietary energy source in farm animals.
  11. Glycogen
    Polysaccharide consisting of a large number of glucose units joined together by ? 1-4 bonds, is a long term energy storage in animal cells and is made primarily by the liver and muscles
  12. Glycolysis
    Series of chemical reactions that split 6 C glucose into 2 3 C pyruvate(s) and generates 6 ATP
  13. Insertion
    Attachment point to bone (or another muscle) that is moved by contraction
  14. Muscle fiber
    Individual muscle cell found in skeletal muscle
  15. Myofibril
    Slender striated functional subunits of a muscle fiber composed of bundles of myofilaments and are the contractible units of muscle
  16. Myofilaments
    Protein filaments composed of contractible proteins and include actin and myosin
  17. Myoglobin
    Oxygen binding protein found in muscle tissue that contains heme
  18. Myosin
    Fibrous motor protein found in muscle that is associated with the A band that functions in muscle contraction
  19. Origin
    Attachment point to bone (or another muscle) that is not moved due to contraction (anchor)
  20. Perimysium
    Connective tissue that surrounds a bundle (fascicles) of muscle fibers and includes major blood and nerve supply for the bundle
  21. Regulatory protein
    Protein that aid in initiation and termination of contraction process and include tropomyosin and troponin
  22. Resting membrane potential
    Voltage that exists across a membrane when at rest due to a difference in ion concentration
  23. Sarcolemma
    Muscle cell membrane
  24. Sarcomerre
    Functional, repeating, contractible unit of myofibril that is composed of myosin and actin
  25. Sarcoplasma
    Muscle cell contents
  26. Sarcoplasmic reticulum
    Tubular network surrounding each myofibril and located in conjunction with a T tubule and is involved with the regulation of Ca
  27. Skeletal muscle
    Muscle under voluntary control that contains striations and makes up morethan 90% of the muscle we consume from farm animals
  28. Smooth muscle
    Muscle under involuntary control that does not contain striations and is found with in the digestive system, the urinary system and in blood vessels
  29. Structural protein
    Protein critical for maintaining the alignment of myofilaments inside myofibril and attach the myofibril to the sarcolemma and include myomesin
  30. T tubule
    Series of tubules that run perpendicular to sarcolemma and into cytoplasm
  31. TCA cycle
    Series of chemical reactions that convert pyruvate into 3 carbon dioxides and generates 15 ATPs
  32. Tendon
    Dense band of fibrous connective tissue that connects muscle to bone
  33. Thick filament
    Protein filament made up of myosin that is involved with the contractile property of muscle
  34. Thin filament
    Protein filament made up of actin in association with troponin and tropomyosin that is involved with the contractile property of muscle
  35. transverse tuble
    Series of tubules that run perpendicular to sarcolemma and into cytoplasm
