Bangaki mathambo ayindlu the human?

Ngokuqinisekile, abaningi owake wacabanga mayelana amathambo amaningi kanjani abantu. Kuyinto ngenxa inani elikhulu amathambo abantu enze kunalokho kuyinkimbinkimbi umunwe zokukhwabanisa izingalo eligoqiwe futhi waqonda isidumbu sakhe, nokuthi amathambo ukuvikela izitho zangaphakathi nokusondelana ngaphandle. usana skeleton siqukethe amathambo abangaphezu kwamakhulu amathathu. Nokho, njengoba umuntu ekhula, ezinye amathambo fuse ndawonye, ngakho emzimbeni inombolo omdala lamathambo imayelana 206-208. Isimanga ukuthi kungase kuzwakale, kodwa ukusho ngokuthe ngqó ukuthi kungakanani bone umuntu akunakwenzeka.

Lapho umuntu uzalwa, amathambo akhe zithambile Nokho, ziba firmer futhi ezinye zazo kukhule ndawonye ngokuhamba kwesikhathi. Ngokwesibonelo, umntwana ugebhezi abizwa ngokuthi fontanelles - indawo lapho kukhona ezicutshini, okuyinto kamuva indawo kwamathambo izicubu. Kamuva endaweni fontanelle ithambo kukhule ndawonye, futhi le ndawo iba ezicashile. Mayelana kangakanani bone umuntu anakho, e imithombo ehlukahlukene ibonisani Imininingwane ezahlukene, kodwa asikwazi ngokuqinisekile ukuthi abo engaphezu kwamakhulu amabili.

amathambo abantu phezu degree of ubulukhuni ngezinye izikhathi uma kuqhathaniswa steel, kodwa kulula kakhulu ngenxa isakhiwo yayo ukungena nakwamanye amazwe. Ithambo izicubu kwakhiwa kusukela amaseli nempahla intercellular ecebile ngokubhekisela izingxenye amaminerali. Ngaphandle ithambo ngamunye imbozwe periosteum, okuyinto yena, is ebuswa imithambo yegazi eziningi ziklabile ithambo. Isakhiwo amathambo abantu kangangokuthi zingabantu bangakhathaleli muntu ngokuphelele, eziyimpumelelo ezinzwa ayatholakala kuphela periosteum. Ngo ebuntwaneni, inzuzo ithambo udaba eziphilayo enamathiselwe amathambo kuyaqina nokuqina. Ngo abantu abadala, ikakhulukazi asebekhulile, ukwanda izidakamizwa wezinto kubangela ukudleka kwamathambo.

Bone isakhiwo, kanye shape yabo abaphila ngayo ihluke ngokuphelele. Emzimbeni womuntu kukhona flat ithambo, ijabulise noma okuxubile, kanye amathambo womoya. Ngu amathambo ijabulise samukelwa ku eside (kunawo wonke futhi humerus, tibia ithambo we ibhodi lemisindo) kanye emifushane (metatarsal amathambo, pastern, phalanges). Impumuzo wethambo, kanye ukuma kwabo encike ngqo kwi indlela okunamathiselwe nalokho kwemisipha izicubu. Uma kwenzeka imisipha ehlangene ithambo izicubu esebenzisa imisipha kwakhiwa yokhalo protuberance noma neseleko at kwalapho. Uma imisipha kuya periosteum samaqanda, in situ kwakhiwa inkatho uxhumano.

Ngaphakathi ithambo, kumaseli efana sithambile futhi ingaphakathi medullary, umnkantsha itholakala. Ngo izinsana, zonke amathambo asemzimbeni iqukethe obomvu umnkantsha, okuyinto umsebenzi zokuzivikela futhi hematopoietic. Kuyinto inethiwekhi ekhethekile imicu reticular namaseli. Kubantu abadala, obomvu umnkantsha aqukethe kuphela cell sithambile amathambo flat. Ngo izimbotshana umnkantsha lamathambo eside ziphuzi nomnkantsha, okumelelwe ukonakala we stroma reticular nge okunamafutha inclusions.

Ithambo thickest e umzimba womuntu owenziwe kahle kunawo wonke. Kunzima kakhulu ukugqashuka kuyo, kodwa ukwa amathambo kungaholela nemiphumela kuyindaba eqakathekileko. Eceleni Umthambo kunawo wonke itholakala, uma umonakalo lapho umuntu angalahlekelwa okuningi igazi.

Kanjani amathambo amaningi umuntu, uthi, empeleni, kunzima ngempela. abantu ezehlukene zinezidingo ezingafani ithambo uyalandelwa. Ngokwesibonelo, kukhona ezinye izimbambo extra, futhi umuntu lapho, futhi umunwe lesithupha. Mayelana oyedwa aphume amabili has onqenqemeni wanezela ukuthi Kuyathakazelisa - ebukhoneni ngokweqile ubambo besilisa kwande ngaphezu wobulili fair. Abanye abantu babe amathambo ezengeziwe eziningana elise igobela le unyawo.
