Lawv muaj ntau yam nuclei thiab cov no cov nuclei yog nyob ntawm ib puag ncig ntawm ntawm tes . Pob txha nqaij yog striated. Cov leeg nqaij leeg tsis ntev npaum li lub cev pob txha cov leeg nqaij thiab feem ntau yog branched hlwb . Cov leeg nqaij leeg tej zaum yuav yog mononucleated lossis binucleated.
Ib yam nkaus, pes tsawg nuclei nyob hauv cov leeg nqaij?
ob
Ib tus kuj tseem yuav nug tau, puas lub plawv cov leeg nqaij muaj ntau dua ib lub hauv paus? Pob txha nqaij yog tsim los ntawm ntev, zoo li fiber hlwb , uas fuse ua ke raws li lawv tau tsim. Qhov no txhais tau tias txhua tus cov leeg nqaij muaj ntau tshaj ib lub cev vim nws yog tiag tiag ua los ntawm ob peb ua ke hlwb . Txawm hais tias muaj cov kab mob plawv tsawg dua nuclei mas pob txha cov leeg nqaij , lawv tseem suav tias yog ntau yam sib txawv.
Ib qho ntxiv, vim li cas cov leeg mob plawv muaj ntau lub nuclei?
Pob txha nqaij fibers tau ua thaum myoblasts fuse ua ke; nqaij yog li ntawd cov fibers muaj ntau yam nuclei (txhua tus cev pib los ntawm ib qho myoblast). Kev sib xyaw ntawm myoblasts yog qhov tshwj xeeb rau pob txha nqaij (xws li, biceps brachii) thiab tsis yog mob plawv los yog smoothmuscle. Qhov ntawd yog li cas a nqaij cell syncytium tau ua.
Vim li cas cov leeg nqaij Multinucleated?
Pob txha nqaij cov ntaub so ntswg tau muab tso ua ke ua ib puag ncig los ntawm cov nqaij sib txuas. Hauv qab lub tsom iav qhov muag, cov leeg nqaij tshwm striated nrog ntau nuclei squeezed raws daim nyias nyias. Cov cov cell yog multinucleated raws li kev sib xyaw ntawm ntau myoblasts uas fuse tsim txhua qhov ntev nqaij fiber ntau.
