Qhov sib txawv tseem ceeb ntawm histogenesis thiab morphogenesis yog tias histogenesis yog cov txheej txheem uas cov hlwb ntawm cov kab mob thawj cov txheej txheem ntawm embryo sib txawv rau hauv cov ntaub so ntswg tshwj xeeb thiab cov kabmob thaum morphogenesis yog cov txheej txheem uas txiav txim siab qhov kawg ntawm lub cev lossis cov ntaub so ntswg..
Embryogenesis muaj ntau theem. Histogenesis thiab morphogenesis yog ob yam cytogenic uas tseem ceeb. Histogenesis yog qhov tshwm sim los ntawm cov hlwb tsis txawv ntawm peb txheej kab mob sib txawv rau hauv cov ntaub so ntswg uas muaj kev ua haujlwm tshwj xeeb. Hauv qhov sib piv, morphogenesis yog cov txheej txheem uas ua rau lub cev tsim nws cov duab. Ntxiv mus, morphogenesis yog lub luag haujlwm rau cov duab ntawm cov ntaub so ntswg thiab cov kabmob.
Histogenesis yog dab tsi?
Histogenesis yog tsim los ntawm cov ntaub so ntswg tshwj xeeb thiab cov khoom nruab nrog cev los ntawm cov hlwb tsis sib xws hauv cov txheej txheem kab mob tseem ceeb (endoderm, ectoderm, thiab mesoderm) thaum lub sij hawm embryonic txoj kev loj hlob. Nws yog ib qho kev sib koom ua ke ntawm cov xwm txheej tshwm sim thaum lub sij hawm embryogenesis. Histogenesis tuaj yeem pom nyob rau hauv ob qho tib si cellular thiab cov ntaub so ntswg. Ib qho piv txwv ntawm histogenesis yog kev hloov pauv ntawm mesoderm hlwb thaum ntxov rau hauv cov leeg nqaij. Feem ntau, histogenesis tshwm sim hauv ib pawg loj ntawm cov hlwb. Vim yog histogenesis, cov hlwb tshwj xeeb thiab cov ntaub so ntswg tau txais kev ua haujlwm tshwj xeeb.
Daim duab 01: Histogenesis
Thaum lub sijhawm histogenesis, cov hlwb endodermic hloov mus rau hauv cov ntaub so ntswg ntawm lub ntsws, thyroid, thiab pancreas. Mesodermal hlwb feem ntau hloov mus rau hauv cov ntaub so ntswg ntawm cov leeg plawv, cov leeg pob txha, cov leeg du, cov ntaub so ntswg hauv ob lub raum, thiab cov qe ntshav liab. Ectodermal hlwb muab nce rau epidermis thiab pab tsim cov neurons nyob rau hauv lub hlwb, thiab melanocytes.
Morphogenesis yog dab tsi?
Morphogenesis yog txheej txheem uas ua rau kev txhim kho ntawm nws cov duab. Hauv lwm lo lus, nws yog cov txheej txheem lom neeg uas ua rau lub cev ua kom nws cov duab. Nws yog ib qho ntawm peb qhov tseem ceeb ntawm kev loj hlob biology. Yog li, morphogenesis yog lub luag haujlwm rau kev txhim kho cov duab ntawm cov neeg laus los ntawm cov hlwb tau los ntawm cov qe fertilized.
Daim duab 02: Morphogenesis
Thaum xav txog cov ntaub so ntswg thiab cov kabmob, morphogenesis yog cov txheej txheem kom tau txais lawv cov duab, uas yog qhov tseem ceeb rau lawv txoj haujlwm. Qhov tseeb, morphogenesis yog lub luag haujlwm rau cov ntaub so ntswg thiab lub cev lub cev uas txiav txim siab lub cev, lub cev thiab tus cwj pwm ntawm lub cev. Qhov tseem ceeb tshaj plaws, morphogenesis yuav tsum muaj kev tswj hwm ntawm lub cev thiab lub cev ntawm lub embryo mechanics los pab txhawb kev txav ntawm tes thiab kev hloov pauv.
Qee yam piv txwv uas piav qhia morphogenesis:
- Ib tsob ntoo tshiab hloov nws cov duab mus rau ib tsob ntoo ncaj, ceg ntoo lossis tsob ntoo twining
- Tib neeg txoj hnyuv quav ntau zaus kom haum rau hauv lub cev
- Tib neeg lub raum ceg txhawm rau txhawm rau ua kom nws muaj nuj nqis
Dab tsi yog qhov zoo sib xws ntawm Histogenesis thiab Morphogenesis?
- Histogenesis thiab morphogenesis yog ob txheej txheem ntawm embryogenesis.
- Ob txheej txheem tseem ceeb rau cov ntaub so ntswg thiab hlwb kom tau txais lawv qhov tshwj xeeb ua haujlwm.
- Lawv muaj lub luag haujlwm rau cov ntaub so ntswg hauv lub cev.
Qhov txawv ntawm Histogenesis thiab Morphogenesis yog dab tsi?
Histogenesis yog tsim los ntawm cov ntaub so ntswg tshwj xeeb thiab cov kabmob los ntawm cov hlwb tsis sib xws ntawm peb txheej kab mob. Ntawm qhov tod tes, morphogenesis yog cov txheej txheem uas muab cov duab zoo rau cov ntaub so ntswg lossis lub cev. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm histogenesis thiab morphogenesis. Ntxiv mus, histogenesis yog qhov tshwm sim ntawm kev sib txawv ntawm tes, thaum morphogenesis yog qhov tshwm sim ntawm cellular proliferation thiab motility. Yog li, qhov no yog lwm qhov sib txawv ntawm histogenesis thiab morphogenesis.
Summary – Histogenesis vs Morphogenesis
Histogenesis hais txog qhov sib txawv ntawm cov hlwb tsis sib xws ntawm endoderm, ectoderm thiab mesoderm hlwb rau hauv cov ntaub so ntswg tshwj xeeb thiab hauv nruab nrog cev. Cov cell thiab cov ntaub so ntswg tau txais kev ua haujlwm tshwj xeeb vim yog histogenesis. Morphogenesis yog cov qauv kev tsim kho uas muab cov duab kawg ntawm lub cev. Vim yog morphogenesis, cov ntaub so ntswg thiab lub cev tau txais cov duab uas tseem ceeb rau lawv txoj haujlwm. Yog li, qhov no qhia txog qhov sib txawv ntawm histogenesis thiab morphogenesis.
