Osteogenic hlwb dhau los ua osteoblasts uas zais cov pob txha, tsim cov pob txha caj dab. Osteoprogenitor hlwb nkag mus rau cov pob txha mos ntawm epiphysis, sib txawv rau hauv osteoblasts thiab zais osteoid rau pob txha mos matrix.
Yog li ntawd, Osteoprogenitor cells yog dab tsi?
Osteoprogenitor hlwb yog qob hlwb ntawm pob txha thiab tsim osteoblasts. Osteoprogenitor hlwb yog muab los ntawm primitive mesenchymal hlwb . Lawv tsim cov pejxeem ntawm qia hlwb uas tuaj yeem sib txawv rau qhov tshwj xeeb tshaj plaws-kev tsim cov pob txha hlwb (i.e. osteoblasts thiab osteocytes).
Tsis tas li, cov cell twg tsis yog los ntawm cov hlwb osteogenic? Lawv pom nyob rau hauv cov pob txha nto, yog multinucleated, thiab pib los ntawm monocytes thiab macrophages, ob hom ntshav dawb hlwb , tsis los ntawm osteogenic hlwb . Osteoclasts tseem niaj hnub rhuav tshem cov pob txha qub thaum osteoblasts tseem niaj hnub tsim cov pob txha tshiab.
Raws li, hom cell twg muaj peev xwm sib txawv rau hauv osteogenic progenitor cell?
Osteochondroprogenitor hlwb yog progenitor hlwb uas tshwm sim los ntawm mesenchymal qia hlwb (MSC) nyob rau hauv cov pob txha. Lawv muaj peev xwm sib txawv hauv osteoblasts lossis chondrocytes nyob ntawm ntawm cov cim qhia tias lawv tau nthuav tawm, ua rau pob txha lossis pob txha mos nce ntxiv.
Osteogenic hlwb nyob qhov twg?
Cov no osteogenic hlwb tsis txawv nrog kev ua haujlwm siab mitotic; lawv tsuas yog pob txha xwb hlwb uas faib. Tsis paub qab hau osteogenic hlwb tau pom nyob rau hauv cov txheej sib sib zog nqus ntawm periosteum thiab cov leeg. Thaum lawv sib txawv, lawv loj hlob mus rau hauv osteoblasts.

Puas yog lub hauv pliaj thiab lub paj hlwb zoo ib yam?
Lub forebrain (proencephalon) yog qhov loj tshaj plaws ntawm lub hlwb, feem ntau yog cerebrum. Lub paj hlwb tau muab faib ua ob lub paj hlwb hemispheres txuas nrog los ntawm qhov loj ntawm cov teeb meem dawb hu ua corpus callosum. Txhua lub hemisphere tau muab faib ua plaub lub lobes; frontal, parietal, occipital thiab sab nqaij daim tawv lobes
Cov hlwb twg yog cov tshuaj tiv thaiv uas nthuav tawm cov hlwb?
Antigen-presenting cells (APCs) yog ib pawg neeg tsis muaj zog tiv thaiv kab mob uas kho cov kab mob hauv lub cev los ntawm kev ua thiab nthuav tawm cov tshuaj tiv thaiv rau kev lees paub los ntawm qee cov lymphocytes xws li T hlwb. Classical APCs suav nrog dendritic cells, macrophages, Langerhans cells thiab B cells
Cov yam ntxwv zoo li cas ntawm cov leeg pob txha yog lub luag haujlwm rau cov tsos zoo li?
Cov tsos mob ntawm cov nqaij pob txha pob txha yog tshwm sim los ntawm kev rov ua dua ntawm cov proteins actin thiab myosin uas muaj nyob ntawm qhov ntev ntawm myofibrils. Tsaus A bands thiab lub teeb I bands rov ua raws li myofibrils, thiab kev sib raug zoo ntawm myofibrils hauv cell ua rau tag nrho cov xov tooj ntawm tes tshwm striated los yog banded
Puas yog Lub Hlwb Sab laug Lub Hlwb Puas Yog Ib Yam?
Cov ntsiab lus 'sab laug-brained' thiab 'right-brained' tau los hais txog tus cwj pwm hauv cov kab lis kev cai nrov, nrog rau kev xav tias cov neeg uas siv sab xis ntawm lawv lub hlwb ntau dua yog muaj tswv yim, xav thiab xav, thaum cov neeg siv kais. sab laug ntau yog ntau logic, nthuav dav-oriented thiab analytical
Puas yog qhov ua tau zoo ib yam li kev xav ntawm lub paj hlwb?
Muaj qhov sib txawv ntawm qhov muaj peev xwm ua thiab lub paj hlwb xav. Lub peev xwm ua tau yog hluav taws xob polarization ntawm daim nyias nyias ntawm cov hlab ntsha. Kev xav ntawm lub paj hlwb yog kev txav ntawm qhov muaj peev xwm ua tau raws cov hlab ntsha
