Imisipha iyizicubu ezithambile ezitholakala ezilwaneni eziningi. Amangqamuzana emisipha anemicu yamaprotheni e-actin ne-myosin ashelelayo adlule elinye kwelinye, enze ukufinyela okushintsha kokubili ubude nokuma kwengqamuzana. Imisipha isebenza ukukhiqiza amandla nokunyakaza.
Ngokuyinhloko banesibopho sokugcina nokushintsha ukuma, ukuhamba, kanye nokunyakaza kwezitho zangaphakathi, njengokufinyela kwenhliziyo nokuhamba kokudla ngohlelo lokugaya ukudla nge-peristalsis.
Izicubu zemisipha zithathwe ongqimbeni lwe-mesodermal lwamaseli egciwane le-embryonic ngenqubo eyaziwa ngokuthi i-myogenesis. Kunezinhlobo ezintathu zemisipha, yamathambo noma e-striated, eyenhliziyo, futhi ebushelelezi. Isenzo semisipha singahlukaniswa ngokuthi esokuzithandela noma ngokuzenzakalelayo.
Imisipha yenhliziyo nebushelelezi ifinyela ngaphandle kokucabanga futhi ibizwa ngokuzenzakalelayo, kuyilapho izicubu zamathambo zifinyela ngokuyala.
Imisipha yamathambo yona ingahlukaniswa ibe imicu esheshayo futhi ehamba kancane. Imisipha inikwa amandla kakhulu ukugcotshwa kwamafutha nama-carbohydrates, kodwa ukusabela kwamakhemikhali e-anaerobic kuyasetshenziswa, ikakhulukazi imicu esheshayo. Lokhu kusabela kwamakhemikhali kukhiqiza ama-adenosine triphosphate (ATP) ama-molecule asetshenziselwa ukunika amandla ukunyakaza kwamakhanda e-myosin. Igama elithi imisipha lisuselwa kwelesiLatini elithi musculus elisho “igundane elincane” mhlawumbe ngenxa yokuma kwemisipha ethile noma ngenxa yokuthi imisipha efinyela ibukeka njengamagundane ahamba ngaphansi kwesikhumba.
Ngingu-Joost Nusselder, umsunguli we-Tools Doctor, umakethi wokuqukethwe, kanye nobaba. Ngiyakuthanda ukuzama okokusebenza okusha, futhi kanye nethimba lami ngidale izindatshana zebhulogi ezijulile kusukela ngo-2016 ukuze ngisize abafundi abathembekile ngamathuluzi namathiphu okwenza.
