Isixhakangqamu semvelendeni. izinkosa zivezwe ngombala obomvu, amathumbunci avezwe ngohlaza.Isixhakangqamu siwuxhoxho oluyinkimbinkimbi, oluxhuma izinkosa(filaments) zezakhamzimba ezitholakalakwingqimbazana yawo wonkeamangqamuzana, kuhlanganisa nalezozezinungwana nezingunazana. Phakathi kwezimvelendeni(eukoryotes), ijija kusuka endenini yengqamuzana kuyaolwelwesini lwengqamuzana futhi yakhiwa izakhamzimba ezifanayoeziPhilini ezahlukahlukene. Yakhiwa izigcoyi ezintathu eziyinhloko, izinkosancinci(microfilaments), izinkosa ezingaphakathi kanye namathumbuncinci(microtubules), futhi konke lokhu kungakwazi ukukhula ngokushesha noma ukuqaqeka kuye ngezidingo zengqamuzana.
