Zingaphi amathambo abo na abantu?

Ngokuqinisekileyo, abaninzi baye Ukhe wacinga na ngendlela amathambo amangaphi ebantwini. Kuyinto ngenxa yenani elikhulu amathambo abantu benza kunokuba nzima iingalo finger nokuqhathwa esongiweyo kunye ayinakolulwa umzimba wakhe, yaye amathambo ukukhusela amalungu zangaphakathi nokubhenca ngaphandle. usana skeleton luquka amathambo abangaphezu kwamakhulu amathathu. Noko ke, njengomntu phezulu likhula, ezinye amathambo fuse kunye, ngoko umzimba inombolo omdala lamathambo imalunga 206-208. Isimanga njengoko kusenokuba ixilongo, kodwa ukuba nithi indlela ithambo engakanani umntu akwenzeki.

Xa umntu azalwe, amathambo akhe ithambile, kunjalo, baba kumcacele yaye abanye babo kukhule ndawonye ngokuhamba kwexesha. Ngokomzekelo, usana, yaba lukakayi kuthiwa fontanelles - indawo apho kukho inyama nokuqina, nto leyo ithathwa nye kwezihlunu amathambo. Kamva kwi ndawo fontanelle ithambo zikhula kunye, yaye le ndawo ibe ezingaqondakaliyo. Malunga nendlela ithambo engakanani umntu, ngemithombo eyahlukeneyo lubonisa iinkcukacha ezahlukeneyo, kodwa ngokuqinisekileyo sithi babo amakhulu ngaphezulu kwe amabini.

amathambo abantu phezu iqondo yokuqaqadeka ngamanye amaxesha xa kuthelekiswa ngentsimbi, kodwa kulula kakhulu ngenxa kulwakhiwo lwalo amazwe. Ijwabu bone wabumba iiseli, nengqwebo intercellular ukuba zizityebi kumacandelo kwezimbiwa. Ngaphandle bone ngamnye kuhlawulwa liSebe periosteum, nto leyo, ukuba luphokoke imithambo yegazi ezininzi lokondla ithambo. Ubume amathambo babantu abanjalo ukuba engavakalelwayo ngokupheleleyo, ezi kwalapho zifumaneka kuphela periosteum. Ebuntwaneni, ukugqithisela ithambo into ephilayo eqhotyoshelwe amathambo luthambe kunye nokuqina. Kubantu abadala, ingakumbi abantu abadala, ukwanda kwezinto ezingaphiliyo kubangela kwamathambo.

isakhiwo Bone, ngokunjalo imilo yabo yahluke kakhulu. Emzimbeni womntu kukho tyaba ithambo, tubular okanye oxutyiweyo, ngokunjalo amathambo anomoya. Ngu amathambo tubular elamkeleke ukuba elide (lithambo kunye ihumerus, lesiquluba lithambo zengalo) kunye elifutshane (amathambo amadeo, pastern, phalanges). Isiqabu wethambo, ngokunjalo imilo yabo ixhomekeke ngqo kwi indlela loncamathiselo noko kwezihlunu kwezihlunu. Kwimeko umsipha edibene inwebu ithambo ngokusebenzisa imisipha kwakhiwa kummango nesisu okanye umhlehlo kwi kuhlangana. Ukuba imisipha iya ngqo periosteum, behleli-apho ukusekwa uqhagamshelo isisele.

Ngaphakathi wethambo, iiseli ukwimo nomsi- kunye kwisisu medullary, lomongo wethambo lilapha. Xa kubelekwa, onke amathambo amathambo iqulethe lomongo wethambo ebomvu, nto leyo umsebenzi zokuzikhusela hematopoietic. It is a womnatha ekhethekileyo Imisonto reticular kunye neeseli. Xa abadala, nomongo ebomvu ziqulethe kuphela iseli nomsi- amathambo flat. Kule ukuqanda lomongo wethambo wamathambo ubude nomongo etyheli, nto leyo limelwe ukonakala le stroma reticular kunye inclusions okunamafutha.

Ithambo echumayo emzimbeni womntu yifemur. Kunzima kakhulu ukuba ukwahlukana, kodwa ezinjengokwaphuka emathanjeni kunokukhokelela nemiphumela emibi kakhulu. Ecaleni kwemithambo yifemur ikhona, xa kwimeko umonakalo apho umntu aphulukane ligazi elininzi.

Indlela amathambo ezininzi abantu, nithi, enyanisweni, kakhulu kunzima. Abantu ezahlukeneyo izixa ezahlukeneyo ithambo waphawula. Umzekelo, kukho ezinye ubambo ezongeziweyo, kwaye umntu apho, kunye ngomnwe wesithandathu. Malunga omnye umntu aphume amabini unalo ngohlangothi wongezelela ebangel 'umdla - phambi ubambo kwemfuneko oyindoda kuxhaphake kakhulu kunokuba besini enobulungisa. Abanye abantu baye amathambo eziliqela ezongezelelweyo elime kule arch yonyawo.
