Qhov sib txawv tseem ceeb ntawm oocyte thiab follicle yog tias oocyte yog lub qe tsis paub qab hau uas ua rau meiosis thiaj li tsim tau lub qe qe loj thaum lub follicle yog cov kua dej uas muaj cov qe tsis paub tab lossis oocyte.
Oogenesis yog txheej txheem nyuaj uas tsim cov poj niam gametes lossis qe qe. Nws pib txawm ua ntej yug tus poj niam tus me nyuam. Oocytes yog cov poj niam gametocytes uas dhau los ua meiosis los ua lub ov. Lawv yog cov tsis paub qab hau diploid hlwb pom hauv cov follicles. Follicles yog cov hnab me me uas muaj dej. Txhua lub follicle muaj peev xwm tso tawm lub qe qe loj rau fertilization. Oocytes faib los ntawm ob lub meiotic cell faib nyob rau hauv thiaj li yuav tsim mature qe hlwb los yog ova.
Oocyte yog dab tsi?
Ib tug oocyte yog ib lub qe uas tsis paub tab pom nyob rau hauv lub follicle. Nws yog tsim thaum lub sij hawm poj niam gametogenesis. Oocyte undergoes meiosis los tsim ib lub qe loj los yog qe cell. Thaum ib tug oocyte pib maturation thiab faib, nws yog hu ua thawj oocyte. Thawj oocyte yog tom qab ntawd raug rau thawj qhov kev faib meiotic thiab tsim cov oocyte thib ob. Qhov thib ob oocyte yog ib tug poj niam tsis paub qab hau gamete tsim tom qab ua tiav ntawm meiosis I. Qhov thib ob theem ntawm meiosis raug ntes mus txog rau theem nrab oocyte yog fertilized nrog cov phev. Tsis ntev tom qab fertilization, theem nrab oocyte undergoes meiosis II thiab tsim ib lub qe loj hu ua ovum. Lub ovum nucleus fuses nrog cov phev nucleus thiab tsim cov zygote, uas tuaj yeem loj hlob mus rau ib tus neeg.
Daim duab 01: Oocyte
Dab tsi yog Follicle?
Ib lub follicle yog ib lub hnab me me uas muaj kua hauv cov poj niam zes qe menyuam. Lawv yog roughly spheroid cellular aggregations. Feem ntau, ib lub zes qe menyuam muaj 8 mus rau 10 follicles. Lawv tuaj yeem yog 2 hli txog 28 hli. Cov follicles muaj cov qe tsis paub qab hau hu ua oocytes. Follicle nourishes thiab tiv thaiv oocyte. Txhua lub follicle muaj peev xwm tso tawm lub qe loj los yog ovum rau fertilization. Hauv kev coj khaub ncaws ib txwm muaj, ib lub follicle yuav loj dua kom txog thaum nws tawg ntawm ovulation kom tso lub qe. Qhov no tshwm sim rau hnub tim 14th hnub tom qab pib kev coj khaub ncaws. Ntxiv mus, follicles secrete cov tshuaj hormones uas cuam tshuam rau theem ntawm kev coj khaub ncaws thiab tso tawm cov tshuaj hormones tseem ceeb.
Daim duab 02: Follicle
Follicle loj thiab xwm txheej yog cov ntaub ntawv tseem ceeb thaum kev ntsuam xyuas kev xeeb tub thiab kev kho mob. Kev kuaj pelvic ultrasound tuaj yeem ntsuas qhov loj thiab tus naj npawb ntawm cov follicles nyob hauv zes qe menyuam. Qe zoo thiab suav cov follicle yog ob yam tseem ceeb uas cuam tshuam rau kev xeeb tub. Tus naj npawb ntawm cov follicles hauv zes qe menyuam qhia txog lub xeev ntawm fertility. Lub qe zoo nyob ntawm hnub nyoog thiab kev ua neej.
Dab tsi yog qhov zoo sib xws ntawm Oocyte thiab Follicle?
- Follicle thiab oocyte yog ob lub qauv pom hauv poj niam lub zes qe menyuam.
- Follicles muaj oocytes.
- Ib qho follicle muaj peev xwm tso lub qe loj lossis ovum.
Qhov txawv ntawm Oocyte thiab Follicle yog dab tsi?
Ib oocyte yog ib lub qe tsis paub tab thaum lub follicle yog ib lub hnab ntim me me. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm oocyte thiab follicle. Raws li txoj cai, oocyte yog ib lub cell diploid thaum lub follicle yog cellular aggregation. Yog li, nws yog lwm qhov sib txawv ntawm oocyte thiab follicle.
Ntxiv mus, qhov sib txawv ntxiv ntawm oocyte thiab follicle yog tias oocyte faib los ntawm meiosis los tsim cov qe qe rau fertilization thaum lub follicles noj thiab tiv thaiv oocytes, tso tawm cov tshuaj hormones tseem ceeb thiab hloov mus rau hauv corpus luteum tom qab ovulation.
Summary – Oocyte vs Follicle
Lub oocyte yog ib lub qe tsis paub tab. Nws yog ib tug diploid cell uas undergoes meiosis los tsim cov qe loj. Lub zes qe menyuam follicle yog lub hauv paus ntawm poj niam kev yug me nyuam biology. Nws yog ib lub hnab ntim dej uas muaj oocyte. Follicle loj hlob thiab loj dua thiaj li yuav tawg thiab tso lub qe. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm oocyte thiab follicle.
