Qhov Tseem Ceeb - Endometrium vs Myometrium
Lub tsev menyuam yog suav tias yog ib qho ntawm cov qauv tseem ceeb tshaj plaws ntawm cov poj niam cev xeeb tub. Nws muab ib puag ncig rau kev loj hlob ntawm fetus thaum fertilization tiav thiab tsim zygote. Yog li ntawd, tus qauv ntawm lub tsev menyuam yog ib qho tseem ceeb rau kev ua haujlwm ntawm lub tsev menyuam uas tau hais los saum no. Cov cheeb tsam sib txawv ntawm lub tsev menyuam, tshwj xeeb tshaj yog peb txheej ntawm phab ntsa uterine muab cov haujlwm sib txawv rau kev loj hlob thiab kev loj hlob ntawm tus menyuam hauv plab thaum cev xeeb tub. Uterine phab ntsa yog tsim los ntawm peb lub ntsiab txheej, endometrium, myometrium thiab perimetrium. Lub endometrium yog tam sim no nyob rau hauv lub puab txheej txheej ntawm lub tsev me nyuam phab ntsa thiab yog tsim ntawm columnar epithelium thaum lub myometrium yog tam sim no nyob rau hauv nruab nrab muscular txheej thiab yog tsim los ntawm cov leeg nqaij fibers. Qhov no yog qhov sib txawv tseem ceeb ntawm endometrium thiab myometrium.
Endometrium yog dab tsi?
Nyob rau hauv cov ntsiab lus ntawm peb txheej ntawm cov phab ntsa mammalian uterine, lub endometrium yog innermost epithelial txheej. Myometrium thiab perimetrium coj qhov no mus rau sab nraud. Lub endometrium yog tam sim no raws li ib txheej ntawm epithelial hlwb nrog rau ib tug mucous daim nyias nyias. Txij li thaum endometrium ua raws li cov txheej txheem basal ntawm phab ntsa uterine, nws raug suav tias yog txheej txheej ua haujlwm tshaj plaws ntawm peb txheej. Thaum lub sij hawm cev xeeb tub, endometrium tau thickens, thiab thaum kawg ntawm lub voj voog nws raug tshem tawm los yog los.
Thaum cev xeeb tub, qhov loj ntawm cov qog sib txawv thiab cov hlab ntsha uas muaj nyob rau hauv endometrium nce. Lub thickness ntawm lub endometrium uas yog enriched nrog cov hlab ntsha thiab glandular ntaub so ntswg muab qhov zoo tshaj plaws ib puag ncig tej yam kev mob rau lub implantation txheej txheem ntawm lub blastocyst (ib tug qauv tsim los ntawm lub zygote thaum fertilization tiav). Kev cog qoob loo thiab kev loj hlob ntawm blastocyst yog suav tias yog lub luag haujlwm tseem ceeb ntawm endometrium.
Daim duab 01: Endometrium
Cov txheej txheem endometrial epithelial yog tsim los ntawm ib txheej ntawm columnar epithelium. Nws muaj ib tug stroma uas lub epithelial txheej so. Lub stroma yog ib txheej ntawm cov ntaub so ntswg sib txawv uas tuaj yeem sib txawv nws cov tuab raws li cov cim hormonal sib txawv. Thaum tus poj niam muaj hnub nyoog yug me nyuam, ob txheej txheej ntawm cov endometrium uas yog, cov txheej txheem ua haujlwm thiab cov txheej txheem basal tuaj yeem txheeb xyuas. Cov txheej txheem ua haujlwm yog tam sim no nyob ib sab ntawm lub uterine kab noj hniav. Cov txheej no yog sloughed kiag li thaum cev xeeb tub. Lub basal txheej yog tam sim no hauv qab cov txheej txheem ua haujlwm thiab nyob ib sab ntawm myometrium. Cov txheej no tsis yog sloughed thaum cev xeeb tub tab sis khaws cia kom zoo rau cov txheej txheem rov ua haujlwm.
Myometrium yog dab tsi?
Myometrium yog txheej nruab nrab ntawm phab ntsa uterine. Nws yog tsuas yog tsim los ntawm cov leeg nqaij txheej uas tsim los ntawm uterine myocytes; ib hom cell tshwj xeeb uas yog tshwj xeeb rau lub tsev menyuam. Myometrium muab kev txhawb nqa txaus rau cov ntaub so ntswg stromal thiab vascular. Txawm li cas los xij, qhov induction ntawm uterine contractions yog suav tias yog lub luag haujlwm tseem ceeb ntawm myometrium.
Myometrium nyob nruab nrab ntawm endometrium thiab perimetrium ntawm phab ntsa uterine. Hauv nws cov txheej txheem ultrastructure, myometrium muaj 03 cov leeg nqaij sib txawv. Ib txheej txheej feem ntau ntawm cov myometrium yog tsim los ntawm cov leeg ntev ntev thaum cov txheej txheem nruab nrab muaj 08 cov leeg nqaij nrog cov qauv crisscrossing. Cov txheej txheej sab hauv ntawm myometrium muaj cov leeg leeg. Lub xub ntiag ntawm crisscrossing qauv nyob rau hauv nruab nrab txheej pab nyob rau hauv kev tiv thaiv ntawm cov ntshav los ntawm lub tsev menyuam thiab yog lub luag hauj lwm rau txoj kev loj hlob ntawm uterine convolutions.
Daim duab 02: Myometrium
Cov nqaij leeg muaj nyob hauv myometrium zoo ib yam li cov leeg nqaij uas muaj nyob hauv lwm thaj tsam ntawm lub cev. Actin thiab myosin yog ob lub ntsiab contractile proteins uas muaj nyob rau hauv cov nqaij leeg. Cov leeg nqaij du ntawm myometrium yog tsim los ntawm actin fibers ntau dua li myosin. Qhov no yog los pab txhawb lub uterine contraction nyob rau hauv ntau cov lus qhia thaum lub sij hawm cev xeeb tub. Tag nrho cov leeg nqaij yog tsim los ua haujlwm tseem ceeb ntawm myometrium uas yog kev cog lus ntawm uterine.
Dab tsi zoo sib xws ntawm Endometrium thiab Myometrium?
- Ob leeg yog cov txheej txheem ntawm lub tsev menyuam phab ntsa.
- Ob leeg pab hauv kev ua haujlwm thiab kev loj hlob ntawm lub tsev menyuam.

Summary – Endometrium vs Myometrium
Ntau thaj chaw ntawm lub tsev menyuam, tshwj xeeb tshaj yog peb txheej ntawm phab ntsa uterine muab cov haujlwm sib txawv rau kev loj hlob thiab kev loj hlob ntawm lub tsev menyuam thiab nrog rau tus menyuam hauv plab thaum cev xeeb tub. Cov txheej txheem endometrial epithelial yog tsim los ntawm ib txheej ntawm columnar epithelium. Ob txheej txheej ntawm endometrium; Cov txheej txheem ua haujlwm thiab cov txheej txheem basal tuaj yeem txheeb xyuas tau thaum tus poj niam tau txais nws lub hnub nyoog yug me nyuam. Cov txheej txheem ua haujlwm yog sloughed kiag li thaum cev xeeb tub. Lub luag haujlwm tseem ceeb ntawm endometrium yog muab qhov zoo tshaj plaws ib puag ncig rau kev cog qoob loo ntawm blastocyst. Myometrium yog suav tias yog txheej nruab nrab ntawm phab ntsa uterine. Nws yog tsuas yog tsim los ntawm cov leeg nqaij txheej uas tsim los ntawm uterine myocytes. Lub luag haujlwm tseem ceeb ntawm myometrium yog ua kom lub cev txav mus los. Qhov no yog qhov txawv ntawm endometrium thiab myometrium.
