Nohlaka lwamathambo namaqembu ezinkulu kwemisipha

uhlelo kwemisipha libhekisela omunye wemizila ebaluleke kakhulu subsystems yemvelo lapho umzimba wenza ukunyakaza ahlukahlukene.

Singasho imelelwa iqoqo kwemisipha Imicu yotshani uyakwazi ukusikwa. I imicu eminingana akuhlanganisileyo izinyanda, akha izicubu, njengobe atsandza imitimba ekhethekile noma ngokwabo faka izitho zangaphakathi. Yemisipha lingaphezulu kakhulu kunalelo nezinye izindikimba: kwezinye izilwane kuba amaphesenti angu-50 esisindo, futhi indoda - amaphesenti angu-40. uhlelo kwemisipha iguqula chemical amandla angaguqulwa abe ukushisa kanye namandla lokukhanda.

ezicutshini kwemisipha

Ngo ezilwaneni ezinomgogodla, ezicutshini kwemisipha luhlukaniswe amaqembu ezilandelayo:

• Ukuphathwa kwabathintwayo, iqukethe imisipha kwangaphakathi futhi kwakhiwe nasemilenzeni. Lokhu kuhlanganisa imisipha lwamathambo.
• Visceral (ingxenye viscera). Kuyinto imisipha bushelelezi futhi inhliziyo.

Uhlelo kwemisipha yomuntu

imisipha yohlaka kuthiwa striated abantu nokunqunywa izimo. Banamathele amathambo futhi cylindrical ubude fiber 1-10 cm.

kwemisipha ngamunye fibre - kuyinto cytoplasm undifferentiated (sarcoplasm) nge cores ngaphezulu wahlela azungeze. Azungeze kuhlanganisa umahluko myofibrils striated. Uzungeze azungeze emgodleni esobala (sarcolemma), esakhiwa collagen fibrils. Iqembu elincane imicu uzungezwe endomysium; ezinkulu imisipha compounds kukhona izinyanda zemicu, wenza phakathi peremizy kwangaphakathi; umsipha ngamunye lizungezwe peremiziem yangaphandle. Muscle kanye ezicutshini uyaqhubeka nomunye futhi oxhumene. Yonke imisipha is ebiyelwe emgodleni ngokuthi fascia. nohlaka lwamathambo kuhlanganisa izicubu, ngalinye elikwazi ixhunywe imizwa nemithambo yegazi futhi bakwazi ukungena kubo.

Imisipha ukusiza ukugcina ukulinganisela zomzimba, ukuba sifeze ukunyakaza emkhathini kanye nokunyakaza esibalulekile zonke izingxenye zomzimba.

imisipha Smooth zitholakala Imithambo yegazi kanye izitho zangaphakathi. Ubude lolu hlobo imisipha kuyinto 0.02-0.2 mm. Bona beswela striation, isimo sabo sifana uthi lokuphotha. bushelelezi imisipha amaseli okusaqanda maphakathi ekujuleni kwenhliziyo.

imisipha Smooth ukusiza ezokuthutha ukuthi iqukethwe izitho eziyize (ukudla emathunjini, isibonelo). Ababandakanyeka ukulawulwa ingcindezi, ukwanda ukusikwa umfundi, nezinye izinhlangano zenkululeko zomzimba. Ukuze imisipha bushelelezi wemfanelo autonomic nesimiso sezinzwa.

uhlelo zemisipha kuhlanganisa imisipha yenhliziyo, okuyinto itholakala kuphela odongeni inhliziyo. Yena njalo encishisiwe esaphila, ukuhlinzeka ukugeleza kwegazi ngokusebenzisa izitsha okunomsoco izinto kwezicubu kudingekile eziyishumi nemitshingo.

Kokudonseka uhlelo

Umzimba womuntu liqukethe imisipha 400 striated, okuyinto ziyancipha ngaphansi kokulawula isimiso sezinzwa esiyinhloko.

Kokudonseka simiso sihlanganisa imisipha, amathambo, imisipha, amalunga omzimba, nemisipha futhi uqwanga ezakha cishe u 75% isisindo emzimbeni. Lolu hlelo unika umzimba womuntu umumo othile, ivumela ukuba ime uhambe. Skeleton kuya kwezitho nezicubu ukhonza njengoba skeleton, futhi ivikela izitho ezibalulekile ekulimaleni. Amathambo buthelela amaminerali ezifana phosphorus kanye calcium. Ingaphakathi ithambo umelwe ngu umnkantsha iqhaza ekwakhiweni egazi (amangqamuzana abomvu, amangqamuzana amhlophe nezinhlayiya zegazi).

Lapho ukulimala nezifo noma iyiphi ingxenye uhlelo zemisipha kuyinto statics okhathazekile kanye namandla okubakhona wonke umzimba. Ngaphezu kwalokho, unesifo lonke uhlelo zemisipha, izitho zangaphakathi kakhulu, kuphele usebenze kahle. Ngokwesibonelo, by kunciphisa omunye izitho kuyinto nomgogodla lwalugobile, elibangela ukusonteka kwesifuba, njengoba phetho - uhlushwa izitho kwegazi kanye ukuphefumula.
