Hauv endochondral ossification , pob txha mos tau tsim los ua lub hauv paus uas cov pob txha tshiab tau tso. Intramembranous ossification yog qhov ncaj qha tso ntawm cov pob txha mus rau hauv cov ntaub so ntswg thaum ntxov (mesenchyme) thiab tsis muaj cov pob txha nruab nrab cuam tshuam.

Ua raws li qhov no, qhov sib txawv tseem ceeb ntawm endochondral ossification thiab intramembranous ossification yog dab tsi?

Txhua pob txha tsim yog txheej txheem hloov pauv. Thaum lub sij hawm kev loj hlob, cov ntaub so ntswg yog hloov los ntawm cov pob txha thaum lub sij hawm ossification txheej txheem. Hauv intramembranous ossification , pob txha txhim kho ncaj qha los ntawm cov ntawv mesenchymal txuas cov ntaub so ntswg. Hauv endochondral ossification , pob txha tsim los ntawm kev hloov cov pob txha mos hyaline.

Tsis tas li ntawd, cov txheej txheem ntawm Intramembranous ossification yog dab tsi? Kev hloov pauv ncaj qha ntawm cov ntaub so ntswg mesenchymal rau hauv pob txha yog hu ua intramembranous ossification . Qhov no txheej txheem tshwm sim feem ntau nyob rau hauv cov pob txha ntawm pob txha taub hau. Hauv lwm qhov xwm txheej, cov hlwb mesenchymal sib txawv rau hauv pob txha mos, thiab cov pob txha mos tom qab hloov los ntawm pob txha.

Ib yam li ntawd, koj yuav nug, Dab tsi yog Intramembranous thiab endochondral ossification?

Intramembranous ossification yog txheej txheem ntawm kev txhim kho pob txha los ntawm cov kab mob fibrous. Endochondral ossification yog cov txheej txheem ntawm pob txha loj hlob los ntawm hyaline pob txha mos. Cov pob txha ntev ua ntev li chondrocytes faib thiab zais cov pob txha mos hyaline. Osteoblasts hloov cov pob txha mos nrog pob txha.

Dab tsi yog 2 hom ossification?

Muaj ob hom ntawm pob txha ossification intramembranous thiab endochondral. Txhua yam ntawm cov txheej txheem no pib nrog mesenchymal cov ntaub so ntswg precursor, tab sis yuav ua li cas nws hloov mus rau hauv pob txha txawv.
