Qhov sib txawv tseem ceeb ntawm thawj theem nrab thiab theem thib ob yog lawv txoj kev loj hlob thiab xwm; Lub hauv paus follicle tsim los ntawm kev txhawb nqa ntawm primordial follicle, thiab nws muaj ib txheej ntawm follicular hlwb whereas, cov follicle thib ob tsim los ntawm thawj follicle, thiab nws yog preantral follicle muaj ntau txheej txheej ntawm granulosa hlwb. Lub caij no, lub tertiary follicle tsim los ntawm cov follicle thib ob thiab muaj cov kua dej puv kab noj hniav thiab ntau txheej txheej ntawm cuboidal granulosa hlwb.
Folliculogenesis yog txheej txheem tseem ceeb ntawm poj niam kev noj qab haus huv thiab kev nthuav tawm ntawm hom. Nws yog cov txheej txheem kev loj hlob ntawm zes qe menyuam follicles pib los ntawm primordial follicles tsim nyob rau hauv thaum ntxov lub neej thiab culminating nrog ovulation los yog follicular tuag. Follicle tsim yog nruj tswj thiab tswj los ntawm hormonal thiab molecular mechanisms. Ntxiv mus, folliculogenesis yog qhov tseem ceeb vim nws tso cai rau kev sib txuas ntawm qhov tseem ceeb ntawm kev sib deev steroid hormones. Muaj tsib theem kev loj hlob ntawm zes qe menyuam follicles. Lawv yog cov primordial, thawj, theem nrab, tertiary thiab graffian follicles. Raws li lub xub ntiag los yog tsis muaj cov kua dej puv kab noj hniav (antrum) nyob rau hauv lub granulosa compartment, cov follicles no ntxiv muab faib ua preantral follicles thiab antral follicles. Primordial, thawj thiab theem nrab follicles yog preantral follicles thaum tertiary los yog ovulatory los yog Graffian follicles yog antral follicles.
Primary Follicle yog dab tsi?
Ib lub hauv paus follicle yog ib qho follicle uas tsim los ntawm kev txhawb nqa ntawm cov follicle primordial. Nws yog ib tug preantral follicle uas tsis muaj cov kua dej puv kab noj hniav. Lub hauv paus follicle muaj ib txheej ntawm follicular hlwb, thiab nws yog ib tug me me follicle. Tsis tas li ntawd, nws yog ib qho tsis paub tab ntawm zes qe menyuam follicle suav nrog lub zes qe menyuam tseem tsis tau paub thiab ob peb lub hlwb tshwj xeeb epithelial nyob ib puag ncig nws.
Daim duab 01: Folliculogenesis
Oocytes hauv thawj follicle yog ib puag ncig los ntawm ib txheej ntawm cuboidal granulosa hlwb. Lub hauv paus follicle loj hlob, thiab nws tau lees paub los ntawm kev nce hauv oocyte txoj kab uas hla thiab nce ntawm cov xov tooj ntawm tes granulose.
Secondary Follicle yog dab tsi?
Ib lub follicle thib ob yog theem thib peb ntawm kev loj hlob hauv follicle. Nws yog tsim los ntawm lub hauv paus follicle. Zoo ib yam li lub hauv paus follicle, cov follicle thib ob kuj tsis muaj cov kua dej uas muaj kab noj hniav. Yog li nws yog preantral follicle. Raws li txoj cai, cov follicles thib ob yog loj dua cov hauv paus hauv paus. Thawj oocyte nyob rau hauv lub follicle thib ob yog nyob ib puag ncig los ntawm ob peb txheej ntawm granulosa hlwb, abasal lamina thiab theca txheej.
Tertiary Follicle yog dab tsi?
Ib tug tertiary follicle yog theem plaub ntawm kev loj hlob ntawm follicle. Nws yog tsim los ntawm cov follicle thib ob. Lub tertiary follicle muaj cov kua dej uas muaj kab noj hniav los yog antrum, uas tsis muaj nyob rau hauv thawj thiab theem nrab follicles. Yog li ntawd, nws yog antral follicle. Cov tsos ntawm antrum qhia tau hais tias tsim ib tug tertiary follicle. Nyob rau hauv kev sib piv rau cov thawj thiab theem nrab follicles, lub tertiary follicle yog loj nyob rau hauv loj. Tab sis mitotic tus nqi ntawm granulosa thiab theca hlwb pib poob rau hauv tertiary follicles tsis zoo li nyob rau hauv ob hom follicles. Nyob rau hauv lub tertiary follicle, lub oocyte yog surrounded los ntawm ib tug ntau yam txheej ntawm cuboidal granulosa hlwb nrog antral chaw
Dab tsi yog qhov zoo sib xws ntawm Thawj Tsev Kawm Ntawv Qib Siab thiab Tertiary Follicle?
- Primary, secondary thiab tertiary follicles yog peb hom follicles tsim thaum lub sijhawm folliculogenesis.
- Txhua peb hom muaj oocytes hauv lawv.
- Lawv loj hlob thaum laus.
- Lawv lub luag haujlwm tseem ceeb yog txhawb nqa oocyte.
Dab tsi yog qhov txawv ntawm Thawj Tsev Kawm Ntawv Qib Siab thiab Tertiary Follicle?
Lub hauv paus follicle yog ib qho follicle tsis paub tab tsim los ntawm kev txhawb nqa ntawm primordial follicle. Qhov thib ob follicle, ntawm qhov tod tes, yog cov follicle uas tsim los ntawm thawj follicle thiab muaj ntau txheej txheej ntawm granulosa hlwb. Lub caij no, lub tertiary follicle tsim los ntawm cov follicle thib ob, thiab nws muaj ntau txheej txheej ntawm granulosa hlwb thiab antrum. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm thawj theem nrab thiab tertiary follicle. Ntxiv mus, lub hauv paus follicles yog me me. Tab sis, cov follicles thib ob loj dua cov hauv paus hauv paus, thiab cov follicles tertiary loj dua cov follicles thib ob.
Hauv qab infographic tabulates ntau qhov sib txawv ntawm thawj theem nrab thiab theem nrab follicle.
Summary – Primary vs Secondary vs Tertiary Follicle
Primary, secondary thiab tertiary follicles yog peb theem kev loj hlob ntawm zes qe menyuam follicles. Lub hauv paus follicles yog tsim los ntawm thawj follicles thaum lub hauv paus follicles yog tsim los ntawm cov hauv paus hauv paus. Tom qab ntawd, tertiary follicles yog tsim los ntawm theem nrab follicles. Ob lub hauv paus thiab theem nrab cov hauv paus hniav tsis muaj cov kab noj hniav uas muaj cov kua dej hu ua antrum thaum lub tertiary follicle muaj qhov antrum. Tsis tas li ntawd, lub hauv paus follicle muaj ib txheej ntawm granulosa hlwb, thaum ob qho tib si theem nrab thiab tertiary follicles muaj ntau txheej ntawm granulosa hlwb. Yog li, qhov no qhia txog qhov sib txawv ntawm thawj theem nrab thiab tertiary follicle.
