Unyawo lomntu - oku na ilungu lomzimba womntu, nto leyo abantu abaninzi abalaseleyo obeku- bipedal. Waba imihla ngemihla umthwalo omkhulu, ngoko ke uninzi lwabantu ngendlela enye okanye omnye iingxaki ezinxulumene nayo. uyaqhubeka unyawo lomntu iphenjelelwa yimiba ezininzi: Umsebenzi ngokwasemzimbeni, impilo jikelele, umsebenzi kuthetha zezihlangu xi. Zonke ezi kunokukhokelela izifo zomzimba.
Ukuze siqonde indlela uyakwazi ukunciphisa ifuthe elibi yeemeko ezahlukeneyo eziphembelela impilo kweqondo asezantsi kufuneka bafunde into eyenza unyawo lomntu. Eli gunya liquka amalungu kunye namathambo; imisipha nemisipha; izanya; imisipha; imithambo yegazi. unyawo kwabantu Amathambo iqulathe amathambo 26, amaqela amacandelo 3: proximal (waseTarso; yokungqubana-navicular-ngesithende; cuboid; esiphakathi, le medial kunye namathambo ngoonobumba osisi) metatarsus (yakhiwa amathambo ezintlanu ezimfutshane ibekwe phakathi phalanges kunye waseTarso), iminwe (14 amathambo ezenza inxalenye (yokuhlasela)). Kuyaphawuleka ukuba ubhontsi abe phalanges ezimbini, nabo bonke abanye - 3.
unyawo kwabantu komzimba ngenxa ukukwazi lethu ukuhamba ngemilenze emibini. Yintoni na le umzimba? isiseko yaso ithambo le talus sivalisisekile idibanisa kunye tibial. Bayeyona joint neqatha. Umthwalo omkhulu ubunzima bomzimba iwela isithende kunye metatarsals. amathambo amadeo Five uqhagamshele phalanges. Amathambo unyawo inxibelelene nemisipha unoxanduva ukuthembeka amalungu. Zidlala indima ebalulekileyo kunye nemisipha bazibandakanye izihlunu namathambo. Amandla kunye luthambe kwezi kwinyama unika Imicu collagen ezo uyahambelana ngokohlobo intambo. Imicu ibalulekileyo unyawo babizwa ngokuba "Achilles", nto leyo sisongezelelo esihlunwini gastrocnemius. Olubotshelelwe ku kwethambo isithende. Oko kukuthi, oko kwenza umntu ukuba uvuke iinzwane kwaye lukwazi unyawo. Imicu elandisiweyo ukususela ngomva kwizihlunu tibial, inika ngokuniguqula asezibilinini, ixhasa neengqameko yonyawo. nemisipha Small ukudibanisa amathambo. Abanye babo ukwenza philisi ezingqonge amacandelo ngokubambisana ithambo. Igcwele ngolwelo ngokuhlangeneyo.
unyawo Human kuquka ezininzi izihlunu: yomphantsi, ngasemva, intertarsal. Phakathi kwawo ke flexor kunye extensor. zicwangciswe Ezi luvo ziyatyeba, eyinhloko yayo a tibial. Baphuma ngaphakathi iqatha, ivela unyawo. Olu luvo inika intshukumo inani elikhulu izihlunu unyawo kwaye ulunika uvakalelo. Kulungile, kuba igazi emzimbeni ingqamana imithambo ezimbini: tibial ngomva kunye sobuKristu. Omnye wabo lwenzeka kwi kwisiseko, yaye zahlulwe zibe kwamasebe amabini. Le yesibini (ngaphambili) udlula phambi yonyawo, ukwakha arc. ephuma lwemithambo wenziwa usebenzisa umphezulu ezimbini (saphenous ezinkulu nezincinane) kunye umthambo ezimbini nzulu (tibialis cipande kunye ngomva).
Kukho "nasemagumbini 'ekhethekileyo unyawo yabantu. It yakhiwe ibe toe arch nesiphelo elastic isithende. Amathambo unyawo iquka ezimbini arch - ezinqamlezayo kunye longitudinal. Xa umthwalo lomzimba esezantsi yabantu okunempilo isasazwa ngokufanayo kwaye kwenyathelo okanye izigaba esebenzayo. unyawo wesintu phantsi ngasemva (i tuber calcaneal) kunye ngaphambili (metatarsals), ebonelela ngayo iipropati oluhle imithombo.
