Muscle Macroanatomy Muscle Microanatomy Is The Most Intriguing Subject Matter Ever I Love The Sliding Filament Theory Contractions Are SO Awesome Exciting Muscular Energy Fascinating Fibers $100 $100 $100 $100 $200 $200 $200 $200 $300 $300 $300 $100 $100 $200 $200 $300 $300 $300 $400 $400 $400 $400 $400 $400 $500 $500 $500 $500 $500 $500 Surrounds the fascicles of muscle tissue Perimysium Back to Main Screen CT that connects adjacent muscle fibers Endomysium Back to Main Screen A “broad sheet” made up of all 3 types of CT Aponeurosis Back to Main Screen Blood vessels and nerves are located in this CT layer Perimysium Back to Main Screen The human body contains __ types of muscle tissue 3 Back to Main Screen Assist in the regeneration of muscle tissue Satellite Cells Back to Main Screen Electrical impulses conducted by the sarcolemma travel along ________ T - tubules Back to Main Screen 2+ Ca is actively pumped into this part of a muscle fiber Terminal Cisternae Back to Main Screen Interconnect thin filaments of adjacent sarcomeres Z Lines Back to Main Screen Contains an active site for the binding of myosin G actin Back to Main Screen Calcium ions bind to ______ Troponin Back to Main Screen The duration of a contraction depends on the duration of this Stimulus Back to Main Screen This disease – caused by a bacteria - prevents the release of ACh Botulism Back to Main Screen An area of the sarcomere that does change shape is located within the “band” that does not change shape H zone Back to Main Screen The detachment of the myosin cross-bridges is directly triggered by the attachment of ATP to __________ Myosin Heads Back to Main Screen The resting tension in a skeletal muscle Muscle Tone Back to Main Screen A contraction in which the muscle tension rises and the muscle length changes Isotonic Back to Main Screen The tension is less than the resistance Eccentric Contraction Back to Main Screen Trying to pick up a car is an example of this type of contraction Isometric Back to Main Screen This is defined by increasing the stimulation rate until the relaxation phase is eliminated Complete Tetanus Back to Main Screen The energy stored in CP is used to recharge ____ ADP Back to Main Screen The process of using fatty acids to create ATP, CP, etc Beta Oxidation Back to Main Screen The recycling of lactic acid by the liver Cori Cycle Back to Main Screen The depletion of glycogen, lipid and amino acid reserves Fatigue Back to Main Screen Rank the following in order of use within muscle tissue: Glycogen Fatty Acids Creatine Phosphate ATP ATP CP Glycogen Fat Back to Main Screen These fibers are found in the back and calf muscles Slow Fibers Back to Main Screen Densely packed myofibrils and large glycogen reserves are found in these fibers Fast Fibers Back to Main Screen Hypertrophy results in the growth of these fibers Fast Fibers Back to Main Screen Have an extensive capillary network Slow Fibers Back to Main Screen Intermediate fibers use this to generate ATP Carbohydrates or Glycogen Back to Main Screen
