Umsipha esinamandla yabantu

Abantu abaninzi ukubuza umbuzo, yintoni na umsipha yomeleleyo emzimbeni womntu? Yinto eyaziwayo ukuba inani efikelela 640. Phakathi kwazo kukho ezincinane kakhulu, into ke kwindlebe engaphakathi, okanye bakhonze ukulungisa yeso. Kukho kwakhona izihlunu mikhulu: quadriceps, gluteus, trapezius. Nangona kunjalo, i-unique abaninzi ngokuba myocardium. Yena uyakwazi zithotywe, nokuba itsalwa emzimbeni womntu. Ngoko ke yintoni na imisipha inamandla?

A definition echanileyo sinikwe isifundo okhethekileyo. Ngokutsho kwabo, ukomelela izihlunu ixhomekeke zinto zilandelayo:

- inani imicu izihlunu ;

- ixabiso esihlunwini ezibangqongileyo ithambo;

- angela attachment;

- ukubetha kwamaza, nto leyo idala luvo.

Ukuze kwesi parameter, babeka amagama ezithile: izalamane kunye elipheleleyo amandla kwezihlunu. Kwakhona, le yesalkathisi kumiselwa ngokungqinelana mali imithwalo, onako ukuphakamisa umntu ukuphumla.

Umgangatho womsebenzi kuxhomekeke kubuchule izihlunu ukutshintsha kwimo yazo. Ngenxa kunciphiso ukunyuka kwezinga, kuba asezantsi kakhulu lokuphumla. Ngoko ke, abantu abaninzi bathi le inamandla izihlunu umntu - ulwimi. Noko ke, le isigwebo ayilunganga, ekubeni liqumrhu eyakhiwa iinxalenye 16 esihlunwini.

amandla eyenziwe nayo i parameter ebalulekileyo. Kubonakala ukuba izihlunu ndoda inamandla - ukuhlafuna. Inokuba ukuphuhlisa amandla xi 72 kg kwaye imi yendlebe. Loo nto yenza kube yisa emhlathini asezantsi ngexesha ukuhlafuna. Ngokwale got igama layo. Le peculiarity ye indawo ye esihlunwini masseter kukwayamanisa ukuya ithambo. Kukho ezinye izihlunu ukuba enze umsebenzi ofanayo. Ezi ziquka: zexeshana pterygoid, osecaleni medial. Eyokuqala iqala ukusuka ithambo ngaxeshanye. Le pterygoid osecaleni Iqinisekile kwiphiko engaphakathi umlomo, lo medial - kwiinkqubo articular. Kwakhona masseter adibaniselana namanye amaqumrhu lwesakhiwo efanayo ngeli xa bathethayo, nembonakalo yobuso kunye yawning. ukwakheka kwalo ifana unxantathu ezitenxileyo ezinokwenzeka.

Enye into, nto leyo umiselwa imisipha inamandla lomntu ungamandla eqine. Ngokwale into kukhokelela ithole, onako ukubamba ubunzima ukuya kwi 130 kg. Ukuqinisekisa oku, kufuneka sikhwele "ngeenzwane" kwaye chola up ubunzima kancinane. Kulo mzekelo, wonke umthwalo iza kuwa phezu esihlunwini ithole. Le ise ngasemva umlenze. Okulandelayo kuso umsipha soleus ngazo ziqhotyoshelwe isithende usebenzisa umsipha. Kuye isakhiwo esilula (intloko ezimbini), kodwa loxinano izihlunu zomzimba ihamba phambili emzimbeni womntu. umsebenzi wayo kukuba ukuzinzisa umzimba xa ihamba.

Enye salathisi esiza ukumisela umsipha unamandla omzimba womntu - umgudu, encamathele kuyo amathambo. Ngokutsho kwesi salathisi, ungakhetha quadriceps kunye gluteal kwezihlunu. Kananjalo Bafumana eziphelweni asezantsi. Ukongeza, izihlunu ezinkulu yabantu - gluteus. Konke oku kungqinwe iimpawu zayo, eliyinhloko enye yazo kukugcina ukuma umzimba kwindawo tye.

Ngoko ke, lo izihlunu ndoda inamandla - ingcamango edidayo. Ngamnye kubo esilawulwa kophawu ethile. Kodwa inkokeli yokwenene ekunokuthiwa imisipha intliziyo, leyo unyamezelo liphezulu. Nangona ezinye izakhiwo phantsi ukudinwa, isebenza engenazimpazamo kwaye nkqu naxa ubuthongo. Kwaye ke ubomi myocardium nga ngokuba ngaphezu ingxoxo esinzima leyo ziyazalana phezu ukusebenza ngendlela nangakumbi izihlunu skeletal.
