A sarcomere (Greek σάρξ sarx "nqaij", Μέρος meros "ib feem") yog chav nyuaj ntawm cov nqaij leeg nqaij. Nws yog chav tsev rov ua dua ntawm ob kab Z. Cov leeg pob txha tau tsim los ntawm cov leeg leeg tubular (myocytes hu ua cov leeg nqaij lossis myofibers) uas tau tsim hauv cov txheej txheem hu ua myogenesis.
Thiaj li, sarcomere yog dab tsi thiab nws txoj haujlwm yog dab tsi?
A sarcomere yog lub tsev cog lus yooj yim ntawm cov leeg nqaij. Txhua tus sarcomere yog tsim los ntawm ob lub ntsiab lus tseem ceeb ntawm cov protein-actin thiab myosin-uas yog cov txheej txheem ua lub luag haujlwm rau cov leeg nqaij. Cov qauv nrov tshaj plaws uas piav qhia txog kev sib zog ntawm cov leeg yog hu ua txoj kab zawv zawg.
Tsis tas li ntawd, lub luag haujlwm ntawm sarcomere hauv cov nqaij ntshiv yog dab tsi? Sarcomeres muaj peev xwm pib loj, txav mus los ntawm kev cog lus ua ke. Lawv cov qauv tshwj xeeb tso cai rau cov chav me me no los koom tes nrog peb nqaij ' kev cog lus . Cov duab qhia txog pob txha nqaij fiber ntau. Qhov tseeb, cov khoom cog lus ntawm nqaij yog tus yam ntxwv ntawm tus tsiaj.
Tsuas yog li ntawd, dab tsi yog sarcomere yooj yim?
Lub tsev cog lus cog lus ntawm cov leeg pob txha pob txha. Sarcomeres tau muab faib ua pawg ntawm filaments ua los ntawm actin lossis myosin. Thaum lub cev nqaij ntshiv, cov filaments swb ib leeg los ua kom luv ntawm sarcomere.
Tus sarcomere ua haujlwm li cas?
Thaum cov leeg sib cog lus, cov actin raug rub raws myosin mus rau qhov chaw nruab nrab ntawm sarcomere txog thaum cov actin thiab myosin filaments tau sib tshooj tag nrho. Hauv lwm lo lus, rau cov leeg nqaij sib cog lus, tus sarcomere yuav tsum luv. Thaum a sarcomere luv, qee thaj tsam luv thaum lwm tus nyob ntev tib yam.
