The flashcards below were created by user jmejamison on FreezingBlue Flashcards. What would you like to do?


  1. What is the enzyme produced by cellular respiration in skeletal muscle that produces energy required for a muscle to move?
    Adenosine triphosphate (ATP)
  2. When a muscle runs out of ATP, what waste produce causes the tired and sometimes burning feeling of muscle fatigue?
    Lactic acid
  3. Pairs of muscles acting or working together to bring about and stabilize muscle movement?
    Synergistic
  4. What is the strongest tendon in the body and attaches the calf muscle to the calcaneus (heel)?
    Achilles tendon
  5. White, fibrous cordlike structure that serves to connect muscle to bone?
    Tendon
  6. What is a neurotransmitter (chemical) used by nerve endings to send an impulse across a synapse to another nerve, and stimulates the next muscle to contract?
    Acetylcholine
  7. What is it when muscle tension increases, but the muscle does not shorten for example pushing against a wall or pushing an immoveable object?
    Isometric contraction
  8. Place where muscle fiber and nerve endings meet, and a motor neuron comes in contact with a skeletal muscle cell?
    Neuromuscular junction
  9. Abnormal muscle movement or contraction such as twitching and cramping of a muscle caused by low serum (blood) calcium level?
    Tetany
  10. Intercalated disks & involuntary muscle that is striated and found in the heart walls?
    Cardiac
  11. The point at which a muscle begins or is attached to a bone - More-fixed muscle anchored to a nonmoving bone?
    Origin
  12. A bruise; does not require surgery?
    Contusion
  13. Records strength of muscle contraction resulting from electrical stimulation to muscle or procedure that records the electrical activity of muscles?
    Electromyography (EMG)
  14. Muscle and tendon inflammation; same as fibromyalgia (causes chronic pain in muscles and soft tissue surrounding joints. Complaints of dull, aching pain throughout body, stiffness, fatigue, depression, and disturbed sleep.)?
    Fibromyositis
  15. Protrusion (bulging)of an organ or part of an organ through a weakness in a muscle wall?
    Hernia
  16. Autoimmune disease affecting normal transmission of nerve impulses along with progressive weakness and atrophy of muscles (usually starting with facial and eye muscles)?
    Myasthenia gravis
  17. T or F
    All muscle activity is influenced by the nervous system
    True
  18. T or F
    Muscles work in teams to pull, but cannot push.
    True
  19. The 3 main functions of muscles are:
    • Movement
    • Support
    • Heat production
  20. When an individual lifts a heavy object, the muscles shorten and thicken as they contract, this is known as what kind of contraction?
    Isotonic contraction
  21. This type of abnormal contraction is caused when the muscle is stimulated in a series of "rapid fire" impulses?
    Tetany
  22. What is a jerky response to a stimulus?
    Twitch
  23. "Striated" (zebra stripped) or "voluntary" (conscious choice to move) are examples of which muscle, that attach to bone?
    Skeletal
  24. "Involuntary" (unconscious movement) or "visceral" are which type of muscle?
    Smooth
  25. What muscle is "striated" in appearance but "involuntary" or smooth muscle in function?
    Cardiac
  26. Skeletal muscles are voluntary muscles that under a microscope are "zebra striped" or have light and dark bands of muscle fibers. These are known as what?
    Striated
  27. What is the muscle responsible for movement when a group of muscles is contracting at the same time?
    Prime mover or agonist
  28. The point at which a muscle begins or is attached to a bone is its origin. Where it ends is known as what point?
    Insertion point
  29. Quad attachments means?
    Four attachments
  30. What is a deficiency of skeletal muscle, that is as serious a health threat as osteoporosis and involves not only losing strength and endurance, but also gaining fat tissue?
    Sarcopenia
  31. What disease is caused by the bacterium Clostridium tetani, which enters the body through a deep, open wound. Also known as "lockjaw"?
    Tetanus
  32. What is the true name for tetanus?
    Clostridium tetani
