Characteristics of Working Muscles

Characteristics of Working Muscles You has know on discussion previously, that function muscle is as tool motion active And as movement (contraction) Because exists stimulation. However, contract muscle No caused by One stimulation just, but by series stimulation Which its nature sequentially. Muscle Wrong One stimulation will strengthen stimulation Which other. With thereby, will happen tension(tone) Which maximum. Tone Which happen taking place in a way continously. Moment Work muscle own two characteristic, that is antagonist And synergistic. Following will explained about two characteristic muscle the. a. Characteristic Antagonist Muscle It is said antagonist, when work muscles cause influence which its nature contrast. The situation muscles which each other antagonist, for example on work muscles which called extensor (straightens up) And flexor (motion bend), muscle triceps And muscle biceps. In side That, muscle Which Work in a way antagonist happen on muscle- muscle Which Work abductor (away body) And adductor (approach body), for example on movement hand parallel shoulder And attitude motion Which perfect. In side That, muscle Also own characteristic antagonist Which called depressor (to lower) And elevator (to above) , for example on movement ducked And looked up head. Motion antagonist Which other is supinator (flip) And pronators (face down), for example on motion flip And invertpalm hand. Picture 1. Characteristic motion antagonist on muscle. b. Characteristic Synergistic Muscle Movement muscle its nature synergistic, that is motion muscle Which if contract give rise to motion one way. Motion synergistic found on movement looked up palm hand or invert palm hand. Picture 2. Action actin And myosin Mechanism System Motion Muscle For know mechanism motion muscle, two person researcher, that is Hansen And Huxly on year 1955 do study with method observe movement muscle use microscope electron And diffraction ray X. Theory Which stated they Now known with designation theory model Sliding Filament . Theory This state that contraction muscle happen as consequence exists two set filament in in cell muscle contractile. Second set filament the, that is filament actin And filament myosin . Theory in on can explained as following. On moment happen stimulation received by acetylcholine, the stimulation causes the actomyosin to contract (contract). Contraction Which happen need energy. On moment contraction happen, filament actin will walk in between myosin to in zone H (zone H, that is part bright in between two tape dark). With circumstances Which thereby That, happen shortening fiber muscle. However thereby, There is fiber Which still long, that is line m (anisotropy/band dark), whereas line Z (isotropy/band bright) And area H increase short time happen contraction. Part end myosin can related with ATP And hydrolyze ATP the become ADP. Energy released with method prevent transfer ATP to myosin Which changed form become configuration energy tall. Myosin Which energized tall the Then bonded with actin form bridge cross. Furthermore, energy Which stored on myosin will released so that end myosin relax produce energy Which low. Relaxation Which happen will change corner bond end myosin become myosin tail. Bond Which happen between myosin energized low And actin will split, on moment molecule new ATP join with end myosin. Cycle the will Keep going repeated. Emergence Energy For Motion Muscle Adenosine Tri Phosphate Which known as ATP, is producer energy main for muscle contraction. ATP is produced from the oxidation (burning) process carbohydrate And fat. It happened contraction muscle as consequence exists interaction between proteins muscle actin And myosin . ATP-ase Aktomiosin Looks on reaction the, formation actomyosin is results interaction between actin And myosin Which need ATP through help enzyme Which known as enzyme ATP-ase. Source energy other on muscle, that is phosphocreatine. Phosphocreatine This is something form compound phosphate energized tall Which there is on muscle in concentration Which tall. Phosphocreatine No can used in a way direct as source energy, but can give the energy to ADP. Process Lots of it phosphocreatine Which there is on muscle striated, more from five time amount ATP. Process solved ATP And phosphocreatine For produce energy No need oxygen free. By Because That, called process anaerobes. If muscle do contraction in a way continously in period time Which long so muscle will experience fatigue. Matter the happen as consequence down content concentration ATP And phosphocreatine. On the contrary, on moment This precisely will happen increase concentration ADP, AMP, And sour lactate. Source other For produce energy, that is with method change glycogen become glucose. Glycogen is compound Which No late. By Because That, must dissolved formerly become lactacidogen. Lactacidogen This changed become glucose And sour lactate. Glucose Which generated oxidized become CO 2 , H2O , _ And energy. Energy Which released furthermore used For form ATP And phosphocreatine. Process This happen on moment muscle relax , And need oxygen free. By Because That, process relaxation called phase aerobic. Glikogen Laktasidogen laktasidogen glukosa + asam laktat If happen hoarding sour lactate Which too Lots in in muscle, can cause fatigue. Sour lactate Which excessive the will oxidized by oxygen, if too Lots needed oxygen For oxidize sour lactate, so person Which experience it breathe panting.
