MUSCLE TISSUE STUDY GUIDE Pg 1 List 6 functions of muscle 1 2 3 4 5 6 List the structural components of muscle tissue from smallest to largest 1 filament 2 3 4 5 wrapped in wrapped in wrapped in List 3 ways muscle attaches to bone and give an explanation and example for each 1 explanation 2 3 explanation explanation Series Elastic Elements consists of 1 example example example 2 3 4 When a sarcomere contracts it creates one is greater The inefficiency between the two creates the pull on the S E E creates which DRAW AND LABEL A SARCOMERE thin thick filaments bare zone A band I band zone of overlap Z disc titin What protein s make up the contractile protein regulatory proteins thin filament thick filament Briefly explain the sliding filament theory pg 2 How does calcium work with the thin filament in the sliding filament theory What is the purpose of the T tubule the terminal cistern the sarcoplasmic reticulum List the sequence of events that occur during excitation contraction coupling 1 Ach is released from the axon s synaptic knob and crosses the synaptic cleft 2 Ach binds to the muscle s motor end plate myosin heads cross bridges attach to the thin filament Final step recovery stroke A motor neuron plus all the muscle fibers it innervates is called a Which kind of skeletal muscle has more of these Which kind has bigger ones of these List 3 purposes of having motor units 1 pg 3 Define these terms recruitment AKA multiple motor unit summation 2 3 treppe twitch tone Explain the length tension relationship Draw a sarcomere in a good L T R and 2 in a bad L T R pg 4 Direct phosphorylation 1 Glycolysis 1 Aerobic respiration 1 2 1 2 3 1 2 Which ATP Replenishment source produces no lactic acid requires oxygen produces the most ATP is slowest lasts longest runs out more quickly Fill in this chart Advantages 2 1 Disadvantages ATP produced per molecule used Define these terms and give an example isometric contraction isotonic contraction Explain the difference between concentric and eccentric contractions Slow Oxidative Fast Oxidative Fast Glycolytic pg 5 Four things affect the force of a contraction Two things affect the velocity of a contraction 1 2 KNOW THESE FIBER TYPES ATP pathway capillaries many or few myoglobin content color rate of fatigue best suited for What is the purpose of myoglobin 1 2 3 4 Explain peristalsis Explain the stretch relax phenomenon What are the influences that cause a skeletal muscle to contract What influences cause cardiac muscle to contract What influences cause smooth muscle to contract Copyright 2011 Dr Jerry Heckler
