Qhov no tshwm sim thoob plaws ib tus neeg lub neej, nrog ossification thiab resorption (tshem tawm cov pob txha) ua haujlwm ua ke los kho lub cev pob txha thaum loj hlob, tswj cov calcium hauv lub cev, thiab kho micro-fractures tshwm sim los ntawm kev ntxhov siab txhua hnub.
Lub hnub nyoog twg yog qhov kev txhaj tshuaj intramembranous tshwm sim?
txheej txheem no pib ntawm lub thib rau thiab xya lub lim tiam ntawm embryonic kev loj hlob thiab txuas ntxiv txog hnub nyoog nees nkaum tsib; txawm hais tias qhov no txawv me ntsis raws li tus neeg. Muaj ob hom pob txha ossification, intramembranous thiab endochondral.
Puas intramembranous ossification txuas ntxiv tom qab yug me nyuam?
Intramembranous ossification pib hauv utero thaum lub sij hawm fetal loj hlob thiab txuas ntxiv mus rau thaum hluas. Thaum yug los, lub pob txha taub hau thiab clavicles tsis yog tag nrho ossified los yog junctions ntawm lub pob txha taub hau (sutures) kaw.
Lub sijhawm twg hauv lub neej puas muaj qhov ossification loj tshaj plaws tshwm sim?
Tus menyuam yaus / xyoo loj hlob yog lub sijhawm zoo tshaj plaws los txhim kho cov pob txha noj qab haus huv. Lub sijhawm no, kev loj hlob ntawm pob txha tshiab (pob txha tsim) ntau dua li pob txha (pob txha resorption). Lub sijhawm no yog lub sijhawm tseem ceeb los tsim cov pob txha muaj zog. Rau cov neeg laus, cov pob txha loj tshaj plaws tau mus txog thaum nruab nrab-30s lig.
Dab tsi yog theem ntawm ossification?
Cov txheej txheem ntawm pob txha tsim yog hu ua osteogenesis lossis ossification. Tom qab cov hlwb progenitor tsim cov kab osteoblastic, lawv pib nrog peb theem ntawm kev loj hlob ntawm tes sib txawv, hu ua proliferation, maturation ntawm matrix, thiab mineralization..

Puas yog kev tshwm sim lossis kev tshwm sim?
Reveling, kuj spelled reveling, txhais tau tias muaj lub sij hawm zoo, los yog zoo siab rau ib yam dab tsi. Yog tias koj tawm mus ua kev zoo siab rau koj kawm tiav thiab koj haus dej haus, tog thiab muaj lub sijhawm zoo, qhov no yog qhov piv txwv ntawm thaum koj rov qab los .
Puas myelination txuas ntxiv mus thoob plaws lub neej?
Myelination yog txheej txheem tseem ceeb ntawm kev loj hlob uas pib thaum lub hlis thib tsib ntawm tus menyuam hauv plab nrog myelination ntawm lub paj hlwb, thiab txuas ntxiv mus thoob plaws lub neej. Cov kev hloov pauv loj hauv myelination tshwm sim los ntawm 3 lub lis piam mus rau 1 xyoo rau tag nrho cov paj hlwb .
Puas yog nws tshwm sim lossis tshwm sim?
Raws li lub npe qhov txawv ntawm qhov tshwm sim thiab qhov tshwm sim. yog happenchance is a coincidental happen while happenstance is (countable) a chance or random event or random events . Puas yog ib lo lus? Ib qho xwm txheej tsis tau xav txog:
Endochondral ossification txawv ntawm intramembranous ossification li cas?
Hauv intramembranous ossification, pob txha tsim ncaj qha los ntawm cov nplooj ntawv ntawm cov ntaub so ntswg mesenchymal. Hauv endochondral ossification, pob txha txhim kho los ntawm kev hloov cov pob txha hyaline . Dab tsi yog qhov txawv ntawm cov tshuaj intramembranous ossification thiab endochondral ossification?
Lub sijhawm redox tshwm sim dab tsi tshwm sim?
Dab tsi tshwm sim hauv Oxidation-Reduction (Redox) Reaction? Electrons raug xa los ntawm ib qho reactant mus rau lwm qhov thiab oxidation xeev / oxidation naj npawb oxidation tooj Qhov nce hauv oxidation lub xeev ntawm atom, los ntawm cov tshuaj tiv thaiv, hu ua oxidation;
