Cov cov khoom kawg ntawm oogenesis yog oocyte uas yog caj ces diploid. Hloov chaw, spermatogenesis ua plaub haploid spermatozoa.
Ib yam nkaus, tib neeg nug, qhov kawg ntawm Oogenesis yog dab tsi?
Tsuas yog nyiam spermatogenesis , oogenesis koom nrog kev tsim cov haploid hlwb los ntawm thawj lub diploid cell, hu ua thawj oocyte, los ntawm meiosis. Cov kab mob me me no, hu ua lub cev ncov qaumteb, thaum kawg tawg, tawm tsuas yog lub qe menyuam loj dua li cov khoom kawg ntawm oogenesis.
Kuj Paub, dab tsi yog txheej txheem ntawm oogenesis hauv tib neeg? Oogenesis yog txheej txheem ntawm kev tsim ntawm ovum paub tab los ntawm oogonia hauv poj niam. Nws tshwm sim hauv zes qe menyuam. Yog li ntawd, nyob hauv txheej txheem ntawm oogenesis , diploid oogonium tsim tawm ib qho haploid ovum thaum ob lossis peb lub cev ncov qaum.
Ib yam nkaus, tib neeg nug, dab tsi yog tsim tawm thaum oogenesis?
Oogenesis hauv Caenorhabditis elegans Oogenesis yog txheej txheem ntawm kev tsim cov poj niam gamete, piv txwv li, ovum lossis qe. Hauv meiosis, ob ntu sib hloov ntawm kev faib cov cell tsim khoom lub qe haploid, nrog tsuas yog ib daim qauv ntawm txhua tus chromosome, los ntawm diploid oocyte ua ntej ntawm tes.
Dab tsi yog tsim tawm tom qab meiosis I hauv Oogenesis?
Hauv poj niam, txheej txheem ntawm meiosis hu ua oogenesis , txij li nws tsim tawm oocytes thiab thaum kawg yields mature ova (qe). Hauv kev npaj rau meiosis , cov kab mob sib kis tau dhau los ntawm interphase, thaum lub sijhawm tag nrho cov cell (suav nrog cov khoom siv caj ces muaj nyob hauv cov keeb kwm) tau rov ua dua.

Nyuaj kov yog hais txog kev nkag siab los ntawm kev txhawb nqa ntawm cov neeg txais khoom ntawm qhov tsis nkag siab nrog cov teb loj. Hauv kev sib piv, kev kov zoo yog hais txog cov neeg txais khoom ntawm kev nkag siab siab nrog cov chaw txais me me
Qhov txawv ntawm qhov kev xav ua ntej thiab qhov kev xav zaum kawg yog dab tsi?
Kev xav ua ntej yog qhov tsim tawm ntawm tus neeg mob lub qhov ncauj. Qhov kev xav zaum kawg muaj cov ntsiab lus tseeb ntawm cov hniav txheej thiab lawv cov ntaub so ntswg ib puag ncig. Lawv tau siv los ua cov hlau thiab tuag nrog cov ntsiab lus meej ntawm cov hniav txheej thiab lawv cov ntaub so ntswg ib puag ncig
Dab tsi yog qhov kaw pob txha ntawm qhov kawg ntawm sab laug radius?
Qhov tawg tawg nyob deb, tseem hu ua pob txha pob txha, yog kev tawg ntawm ib feem ntawm cov pob txha tawg uas nyob ze rau lub dab teg. Cov tsos mob muaj xws li mob, ua pob, thiab o tuaj sai sai. Cov pob txha ulna kuj tseem yuav tawg tau. Hauv cov neeg hluas, cov pob txha no feem ntau tshwm sim thaum kis las lossis kev sib tsoo tsheb
Dab tsi yog qhov teeb meem ntawm daim tawv nqaij uas tshwm sim los ntawm kev mob ntev ntawm cov qog sebaceous tshwm sim los ntawm cov khoom zais cia?
AKA pob txuv vulgaris- Cov teeb meem ntawm daim tawv nqaij ua rau mob ntev ntawm cov qog sebaceous los ntawm khaws cia tso zis thiab Propionbacterium acnes, lub sijhawm tshawb fawb rau cov kab mob pob txuv. Qhov mob ntawm daim tawv nqaij qhuav, tawv nqaij vim tsis muaj lossis tsis muaj sebum uas tshwm sim los ntawm cov laus thiab los ntawm qhov txias
Dab tsi yog cov khoom ntawm qhov khoom plig txoj kev?
4: Txoj kev muab khoom plig. Ib txoj hauv kev tseem ceeb rau kev nkag siab txog qhov cuam tshuam ntawm cov tshuaj ntawm lub hlwb hu ua txoj kev nqi zog. Txoj hauv kev khoom plig cuam tshuam nrog ntau qhov ntawm lub hlwb, qee qhov uas tau hais qhia hauv daim duab no: thaj tsam ntawm qhov ncauj me me (VTA), cov keeb kwm keeb kwm yav dhau, thiab lub prefrontal cortex
