Unyawo lomuntu - lena ingxenye enkulu yomzimba womuntu, okuyinto abantu ovelele wezinkawu bipedal. Yena nsuku sihlangabezane umthwalo omkhulu, ngakho iningi labantu e ngandlela-thile linezinkinga ephathelene nayo. unyawo lomuntu njalo bathonywa ezicini eziningana: umzimba, impilo jikelele, umsebenzi kusho ingcindezi izicathulo. Konke lokhu kungaholela izifo zomzimba.
Ukuze uqonde ukuthi ungehlisa umthelela ongemuhle izici ezihlukahlukene nomthelela empilweni wemikhawulo aphansi kufanele ufunde nokuthi yini unyawo lomuntu. Leli gunya kuhlanganisa emalungeni namathambo; imisipha kanye nemisipha; nezinzwa; imisipha; imithambo yegazi. unyawo lomuntu Skeleton siqukethe 26 amathambo, zib 3 izigaba: proximal (waseTarsu; ukushayisana; navicular; isithende; cuboid; Lesisemkhatsini, le medial kanye lateral-cuneiform amathambo) metatarsus (sakhiwa amathambo ezinhlanu iDemo elise phakathi phalanges futhi waseTarsu), iminwe (14 amathambo ezakha kumasegmenti (ndlela yokuhlasela yokuhlanganisa izihlangu)). Kuyaphawuleka ukuthi isithupha has phalanges ezimbili, futhi bonke abanye - 3.
unyawo lomuntu anatomy ngenxa ikhono lethu ukuhamba ngezinyawo ezimbili. Kuyini lokhu umzimba? isisekelo salo ithambo we talus uvalwe ixhuma nge tibial. Bakha joint iqakala. Umthwalo oyinhloko esisindo ewela esithendeni futhi metatarsals. amathambo Five metatarsal uxhumeke kwi- phalanges. Amathambo endoda unyawo kuhlotshaniswa emisipheni obhekene ubuqotho amalunga omzimba. Zidlala indima ebalulekile okusenza ujoyine imisipha ukuba amathambo. Amandla kanye kuyaqina yalezi kwezicubu unika collagen ethandele zazo okwakuthandelene ngesimo intambo. Imisipha ebaluleke kakhulu unyawo okubizwa ngokuthi "Achilles", okuyinto isandiso imisipha gastrocnemius. It unamathele ithambo isithende. Okungukuthi, lwenza umuntu uvuke on izinzwane zakho kanye nokuvumelana unyawo. Imisipha esengxenyeni esukela tibial imisipha posterior, ihlinzeka turning kwezibilini, isekela amakhothamo angu unyawo. nemisipha Small ukuxhuma amathambo. Ezinye zazo zakha capsule ezizungezile izigaba ahlangene ithambo. Ligcwele uketshezi ngokuhlanganyela.
ngezinyawo Human kuhlanganisa sebuningini imisipha: amathe, misa, intertarsal. Phakathi kwazo kunane-flexor futhi extensor. Lezi imizwa mkhulu ahlelwe, main okuyinto tibial. Ephuma ngaphakathi iqakala, kubonakala unyawo. Lokhu ezinzwa inikeza ukunyakaza inqwaba imisipha ngezinyawo futhi ulunika ukuzwela. Nokho, ukuze igazi eligciniwe yomzimba oluhambisana imithambo emibili: tibial posterior futhi anterior. Omunye wabo senzeka ngasesinqeni, uluhlukanise phakathi kwamagatsha amabili. Eyesibili (phambili) sihamba phambi ngezinyawo, azakhele arc. outflow emithambo yegazi wenziwa usebenzisa ebusweni ezimbili (saphenous ezinkulu nezincane) kanye umthambo ezimbili ezijulile (tibialis anterior kanye posterior).
Kukhona "vaults" ekhethekile unyawo lomuntu. It is icanjwe njengenhlangano nokunwebeka lwaleli isiphetho uzwane futhi isithende. Amathambo unyawo siqukethe ezimbili lwaleli - transverse kanye longitudinal. Ngo umuntu aphansi esitho umthwalo enempilo isakazwa nombala futhi ngokuvumelana isinyathelo noma izigaba egijima. unyawo lomuntu lihlale phansi at the ezingemuva (tuber calcaneal) kanye phambi (metatarsals), esinikela ngayo izakhiwo obuhle iziphethu.
