Qhov sib txawv tseem ceeb ntawm Graafian follicle thiab corpus luteum yog Graafian follicle yog ib lub hauv paus tshwj xeeb uas muaj cov oocyte thib ob, thaum lub cev luteum yog lub caj pas ib ntus tsim tom qab tso tawm ntawm cov theem nrab oocyte los ntawm Graafian follicle.
Nyob rau hauv biology, folliculogenesis yog kev loj hlob ntawm zes qe menyuam follicles. Graafian follicle, tseem hu ua antral follicle lossis tertiary follicle, yog lub zes qe menyuam follicle tsim thaum lub sijhawm tom kawg ntawm folliculogenesis. Graafian follicle muaj qhov thib ob oocyte. Corpus luteum yog tsim tom qab tso tawm ntawm qhov thib ob oocyte los ntawm Graafian follicle. Lub corpus luteum yog ib pawg ntawm cov hlwb uas tsim nyob rau hauv lub zes qe menyuam. Nws yog lub luag haujlwm rau kev tsim cov tshuaj progesterone thaum cev xeeb tub.
Graafian Follicle yog dab tsi?
Lub Graafian follicle yog lub zes qe menyuam follicle matured thaum lub sijhawm qee yam ntawm folliculogenesis. Nws tseem hu ua antral follicle. Graafian follicle muaj cov kab noj uas muaj kua dej hu ua antrum, nyob ib sab ntawm oocyte. Graafian follicle tshwm raws li cov follicle paub tab. Tsis muaj cov hlwb tshiab pom hauv Graafian follicle. Cov granulosa thiab theca hlwb tam sim no nyob rau hauv Graafian follicle txuas ntxiv mus rau mitosis. Cov txheej txheem saum toj no yog concomitant nrog kev nce hauv antrum ntim. Follicle-stimulating hormone (FSH) txhawb kev loj hlob ntawm Graafian follicle. Graafian follicles tuaj yeem ncav cuag qhov loj me nyob ntawm qhov muaj ntawm FSH hormone.
Daim duab 01: Graafian Follicle
Lub Graafian follicle's granulosa hlwb pib sib txawv ua plaub yam subtypes raws li oocyte-secreted morphogenic gradient. Lawv yog corona radiata; ncig lub zona pellucida, membrana granulose; uas yog sab hauv rau basal lamina, periantral; uas nyob ib sab ntawm lub antrum, thiab cumulus ophorus; uas txuas cov membrana thiab corona radiata granulosa hlwb ua ke. Theca hlwb ntawm Graafian follicle muaj receptors rau LH (luteinizing hormone). LH txhawb kev tsim cov androgens (androstenedione) los ntawm theca hlwb. Androstenedione yog aromatized los ntawm granulosa hlwb los tsim estrogens.
Corpus Luteum yog dab tsi?
Lub Corpus luteum yog cov qauv endocrine ib ntus koom nrog hauv ovulation thiab thaum ntxov cev xeeb tub. Nyob rau hauv qhov tseeb, nws yog ib tug transitory endocrine caj pas uas yog ib tug daj hormone-secreting lub cev. Nws yog tsim tom qab tso tawm ntawm qhov thib ob oocyte los ntawm Graafian follicle. Thaum lub sij hawm ovulation, ib tug dominant mature follicle tso tawm lub qe. Tom qab tso tawm ntawm lub qe thiab tom qab fertilization, lub follicle seals tawm nws tus kheej. Yog li ntawd, nws tsim lub corpus luteum. Corpus luteum secretes ib yam tshuaj hu ua progesterone thaum cev xeeb tub. Lub Corpus luteum yuav txuas ntxiv tsim cov progesterone kom txog thaum lub fetus tsim ib theem txaus los txhawb nqa lub cev xeeb tub. Nws feem ntau tshwm sim ntawm 7-9 lub lis piam ntawm cev xeeb tub. Progesterone tseem ceeb heev thaum cev xeeb tub. Progesterone tso cai rau lub tsev menyuam loj hlob, thiab nws txhawb kev loj hlob ntawm lub tsev menyuam.
Daim duab 02: Corpus Luteum
Ntxiv mus, Corpus luteum kuj tau txais kev txhawb nqa los ntawm cov tshuaj hormone human chorionic gonadotrophin (HCG). Thaum fertilization tsis tshwm sim, lub corpus luteum yuav tawg. Qhov no yuav txo qis cov tshuaj estrogen thiab progesterone. Nws coj mus rau qhov pib ntawm lub caij nyoog poj niam.
Dab tsi zoo sib xws ntawm Graafian Follicle thiab Corpus Luteum?
- Graafian follicle thiab corpus luteum yog ob lub qauv tsim los ntawm zes qe menyuam.
- Ob lub qauv zais cov tshuaj hormones.
- Lawv tseem ceeb heev rau poj niam kev yug me nyuam.
- Kev tsim qauv, ob qho tib si yog cov hlwb loj.
Qhov txawv ntawm Graafian Follicle thiab Corpus Luteum yog dab tsi?
Lub graafian follicle yog cov follicle uas muaj cov oocyte thib ob hauv lub zes qe menyuam. Lub caij no, Corpus luteum yog ib ntus endocrine caj pas tsim tom qab tso tawm ntawm qhov thib ob oocyte los ntawm Graafian follicle. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm Graafian follicle thiab corpus luteum. Ntxiv mus, Graafian follicle secretes estrogen thaum lub corpus luteum secretes progesterone. Tsis tas li ntawd, FSH tswj kev txhim kho thiab kev saib xyuas ntawm Graafian follicle, thaum HCG tswj kev txhim kho thiab kev saib xyuas ntawm corpus luteum. Yog li, qhov no yog lwm qhov sib txawv ntawm Graafian follicle thiab corpus luteum.
Cov infographic hauv qab no teev qhov sib txawv ntawm Graafian follicle thiab corpus luteum hauv daim ntawv tabular.
Summary – Graafian Follicle vs Corpus Luteum
Lub Graafian follicle yog cov follicle uas muaj cov oocyte thib ob. Cov hlwb hauv Graafian follicle pab tsim cov tshuaj estrogen. Corpus luteum yog tsim tom qab tso tawm ntawm qhov thib ob oocyte los ntawm Graafian follicle. Nws yog daj, hormonal secreting lub cev. Qhov loj ntawm cov hlwb hauv corpus luteum tsim cov tshuaj hormone progesterone thaum cev xeeb tub. Yog li, qhov no qhia txog qhov sib txawv ntawm Graafian follicle thiab corpus luteum.
