Ovary vs Uterus
Cov poj niam kev ua me nyuam ntawm tib neeg yog tsim los ntawm cov txheej txheem sab hauv xws li zes qe menyuam, cov hlab ntsha, lub tsev menyuam, lub tsev menyuam, thiab qhov chaw mos thiab cov qauv sab nraud nrog rau qhov chaw mos, labia majora, labia minora, clitoris, vestibule, hymen, vaginal orifice, thiab vestibular qog. Lub luag haujlwm tseem ceeb ntawm cov txheej txheem no suav nrog kev tsim cov qe (oogenesis), kev thauj mus los ntawm cov qe (ovulation), impregnation, kev txhawb nqa ntawm fetal txoj kev loj hlob (gestation), thiab yug ntawm fetus (parturition). Yuav kom ua tiav tag nrho cov haujlwm no, poj niam yug me nyuam yuav tsum muaj qhov sib npaug hormonal zoo.
Ovary
Poj niam deev luag poj niam muaj ob lub zes qe menyuam, uas yog almond-puab thiab zes qe menyuam nyob ntawm txhua qhov chaw ntawm lub tsev menyuam. Txhua lub zes qe menyuam muaj oocytes, uas tsis ntev los no hloov mus rau ova (cov qe loj) thaum lub sijhawm oogenesis. Lub zes qe menyuam yog tuav los ntawm ob lub ligaments hu ua suspensory thiab zes qe menyuam ligaments, thiab tsis txuas rau cov hlab ntsha.
Ob lub luag haujlwm tseem ceeb ntawm zes qe menyuam yog qhov tso tawm ntawm estrogen thiab progesterone, thiab kev loj hlob thiab tso tawm ntawm zes qe menyuam. Tag nrho lub zes qe menyuam yog them nrog cov ntaub so ntswg sib txuas hu ua tunica albuginea. Lub cortex nyob hauv qab tunica albuginea. Lub cortex feem ntau muaj ntau cov follicles hauv ntau theem ntawm kev loj hlob. Lub medulla muaj nyob hauv nruab nrab thiab muaj cov ntaub so ntswg xoob, cov hlab ntsha, lymphatics thiab cov hlab ntsha. Lawv yog homologous rau cov noob qes ntawm txiv neej txoj kev loj hlob.
Yuav Uterus
Teixeira, J., Rueda, B. R., and Pru, J. K., Uterine Stem cells (September 30, 2008), StemBook, ed. Lub Zej Zog Kev Tshawb Fawb Stem Cell, StemBook, doi/10.3824/stembook.1.16.1, Y Uterus yog pear-puab zoo li lub cev nqaij daim tawv nyob rau sab saum toj ntawm qhov chaw mos. Nws yog tuav los ntawm dav, puag ncig, uterosacral ligaments nyob rau hauv lub plab mog thiab tsis txuas rau ib feem ntawm lub cev pob txha. Nws muab qhov chaw rau kev coj khaub ncaws, implantation ntawm fertilized zes qe menyuam, kev loj hlob ntawm tus menyuam hauv plab thaum cev xeeb tub, thiab kev ua haujlwm. Phab ntsa uterine yog tuab thiab muaj peb txheej;
– lub endometrium, uas yog innermost txheej
– myometrium, cov leeg nqaij nruab nrab tom qab, thiab
– perimetrium, uas yog txheej txheej serosal uas npog lub cev ntawm tsev menyuam.
Endometrium ua rau feem loj ntawm lub tsev menyuam thiab muaj cov leeg du. Lub thickness ntawm nws txawv ntawm 0.5 hli mus rau 5 hli. Endometrium kab cov kab noj hniav hauv cov poj niam uas tsis cev xeeb tub thiab muaj ntau cov hlab ntsha thiab cov qog.
Qhov txawv ntawm Ovary thiab Uterus yog dab tsi?
• Poj niam lub cev xeeb tub muaj ob lub zes qe menyuam thiab ib lub tsev menyuam.
• zes qe menyuam nyob ntawm txhua sab ntawm lub tsev menyuam.
• Uterus yog pear-puab lub cev nqaij daim tawv, whereas zes qe menyuam yog lub cev zoo li almond.
• zes qe menyuam tsim cov tshuaj hormones, hos uterus tsis.
• Uterus muaj cov qauv hollow, tsis zoo li zes qe menyuam.
• Ovary muaj ntau cov follicles, tab sis uterus tsis.
• Cov zes qe menyuam loj hlob thiab tso tawm zes qe menyuam thaum lub tsev menyuam yog qhov chaw cog qoob loo ntawm lub zes qe menyuam, kev loj hlob ntawm tus menyuam hauv plab thaum cev xeeb tub, thiab ua haujlwm.
• Cov hlab ntsha hauv plab yog txuas rau lub tsev menyuam, tab sis tsis yog rau zes qe menyuam.
• Ovary muaj peb txheej; tunica albuginea, cortex, thiab medulla, thiab peb txheej ntawm lub tsev menyuam yog endometrium, myometrium thiab perimetrium.
