Umsipha

Imisipha iyizicubu ezithambile ezikhethekile, enye yezinhlobo ezine eziyisisekelo zezicubu zezilwane . Kunezinhlobo ezintathu zezicubu zemisipha ezilwaneni ezinomgogodla :- izicubu zemisipha yogaga, izicubu zemisipha yenhliziyo, kanye nezicubu zemisipha ezibushelelezi . Izicubu zemisipha zinika imisipha yesikhehle ikhono lokubuthaza nokuphumula . Izicubu zemisipha ziqukethe isakhamzimba ezikhethekile zokubuthaza ezibizwa ngokuthi i-actin kanye ne-myosin ezisebenzisanayo ukuze zibange ukunyakaza. Phakathi kwezinye izakhamzimba eziningi zemisipha kukhona nezakhamzimba ezimbili ezilawulayo, i-troponin kanye ne-tropomyosin . ^[1] Imisipha yakheka ngesikhathi sokuthuthukiswa kombungu, enqubweni eyaziwa ngokuthi i-myogenesis . ^[2]
