Presentation Transcript

  1. Muscle Vocabulary from Notes January 20, 2011

  2. Vocabulary to learn… • Myofibrils • Myosin • Actin • Sarcomere • I bands • Z lines • A bands • H zone • Sarcoplasmic reticulum • Thin filaments • Thick filaments • Transverse tubules (T tubules)

  3. Vocabulary to learn, cont. • Motor neurons • Synapse • Motor end plate • Neuromuscular junction • Motor unit • Troponin and tropomyosin ( T & T) • Sliding filament theory/model • Oxygen debt • Muscle fatigue • Threshold stimulus • Latent period • Twitch • Origin & Insertion of a muscle • Agonist, synergist, and antagonist muscle functions

  4. Vocabulary to learn, cont. • Contracture • Convulsion • Fibrillation • Fibrosis • Myalgia • Myokymia • Myology • Myoma • Myopathy • Myotomy • Paresis • Torticollis • Muscular dystrophies • Myasthenia gravis

  5. Concepts to learn • What is the relationship between cellular respiration and heat production? • How are lactic acid, oxygen debt, and muscle fatigue related? • Compare/contrast ATP production in aerobic respiration and anaerobic respiration

  6. Thinking Critically • An Olympic sprinter typically has more than 80% fast twitch muscle fibers. • An Olympic marathoner typically has more than 90% slow twitch muscles. • An average person has about half fast twitch and half slow twitch muscles. • ** Explain the reasoning behind these statistics.
