Ukuze kwezicubu abangothathekile emzimbeni womuntu kukhona izicubu sezinzwa, secretory kanye muscle. Nokho, lona wamuva lihlukile lonke impahla eziyingqayizivele ukusikwa ngenxa yokuba khona e isakhiwo cell we microfilaments we amaprotheni ezikhethekile - myosin, actin, tropomyosin. Lokhu kuqinisekisa ekugcinweni kokuthula ukuma komuntu, ukunyakaza emkhathini, ukukhuthaza ukudla bolus ngokusebenzisa pheshana emathunjini, kwegazi, kanye nokunye. Kuye histological izici, imisebenzi kanye nemvelaphi kukhona ngezigaba ku bushelelezi futhi striated kwemisipha izicubu kwabanye abalobi ukukubona ngowesithathu subsp inhliziyo. izakhi contractile Nokho, kufanele aqondwe bakha kuphela ngesisekelo salezi kwezicubu, futhi babengakucabangi ukusebenza ngempumelelo ngaphandle inethiwekhi aminyene yegazi ukunikeza ukulethwa semali oksijini amandla abalulekile igobolondo zokuzivikela - sarcolemma nokuqiniswa unformed okuxekethile ezicutshini.
Striated
Striated kwemisipha izicubu, ikakhulukazi bakha yonke imisipha yohlaka nezihlanganiso uvumele ukunyakaza futhi alondoloze ngeqholo. iyunithi wezakhiwo futhi functional of a sarcomere, futhi zenziwe e ithuba myosymplasts - Imicu yotshani ezakhiwe ukuhlanganisa sebuningini amangqamuzana ngamanye phakathi kwamangqamuzana. On ukulungiselela histological imisipha striated izicubu kalula zihlukaniswa multi-core kanye striation kungani sebewelele igama labo. Omunye umsebenzi obalulekile isizukulwane ukushisa, ngakho izinga lokushisa lehla a babeqhaqhazela ngenxa yezihlambi zemvula umuntu kwenzeka. Futhi striated kwemisipha izicubu amafomu kanye nesakhiwo esivimba amanzi, cardiomyocytes kuphela kuhluke yokuntuleka symplasts. Lapho microscope, zingabantu fusiform mononuclear amaseli. Bahlukene ngokuvumelana imisebenzi yabo emsebenzini (ubuswa inani) ukuqhuba secretory. Kuyinto sibonga yesibili, inhliziyo striated kwemisipha izicubu babe impahla automatism, okusho unekhono self-shwabanisa, ukuqinisekisa ukuqhubeka inhliziyo. Uhlobo lwesithathu cell iyona indawo zamagama izinto ama-hormone sengathi, ikakhulukazi kuba isici atrial natriuretic itshe esivivaneni diuresis anda.
bushelelezi
Uma kokunikezela ukunyakaza kwemisipha womuntu izicubu - striated, le motility we emathunjini bese ipheshana urogenital, ukuncishiswa semithambo nodonga bronchial ihlinzeka imisipha abushelelezi. It is zihlukaniswa isigqi, yokuhamba isihlobo, ngezinga eliphezulu stretchability namakhono okuzivuselela, kanye innervation autonomic. Lokhu side mononuclear amaseli, ngaphandle striations, futhi amaningi actin collagen e isakhiwo. myocyte ngamunye camera mncane engaphansi ulwelwesi, kanye namaqembu - endomysial okuxekethile ezivela izicubu okungajwayelekile zezinzwa.
