Qhov sib txawv tseem ceeb ntawm mullerian duct thiab wolffian duct yog mullerian duct yog ib qho embryonic qauv uas tsim cov genitalia ntawm poj niam, thaum wolffian duct yog ib qho embryonic qauv uas tsim cov genitalia ntawm cov txiv neej.
Ib lub cev xeeb tub yog ib feem ntawm tus tsiaj uas koom nrog kev sib deev. Thaum kawg, lub cev xeeb tub ua rau lub cev xeeb tub. Nyob rau hauv cov tsiaj, testis nyob rau hauv cov txiv neej thiab lub zes qe menyuam nyob rau hauv cov poj niam yog hu ua thawj lub cev nqaij daim tawv. Tag nrho lwm qhov ntawm lub cev xeeb tub yog hu ua lwm yam kabmob sib deev. Cov kab mob sib deev thib ob tau muab faib ua ob hom xws li cov kab mob hauv nruab nrog cev (sab hauv genitalia) thiab cov kab mob sib deev (sab nraud genitalia). Mullerian duct thiab wolffian duct yog ob lub embryonic qauv uas tsim lub genitalia ntawm poj niam thiab txiv neej, feem.
Mullerian Duct yog dab tsi?
Mullerian duct yog ib qho embryonic qauv uas tsim cov genitalia ntawm poj niam. Hauv cov poj niam, mullerian duct yuav tsim los tsim cov hlab ntsha, lub tsev menyuam, lub tsev menyuam, thiab ib feem peb ntawm qhov chaw mos. Mullerian duct tseem hu ua paramesonephric duct. Mullerian ducts yog khub ducts ntawm lub embryo uas khiav mus rau sab nraud ntawm lub urogenital ridge. Lawv xaus ntawm qhov sinus tubercle nyob rau hauv lub primitive urogenital sinus.
Daim duab 01: Mullerian Duct
Mullerian ducts muaj nyob rau ntawm lub embryo ntawm ob leeg poj niam. Lawv loj hlob mus rau hauv lub cev xeeb tub nkaus xwb nyob rau hauv cov poj niam. Mullerian ducts degenerate nyob rau hauv cov txiv neej ntawm qee hom. Kev loj hlob ntawm Mullerian ducts mus rau hauv lub cev xeeb tub yog nyob rau hauv kev tswj nruj ntawm Mullerian inhibiting factor (anti-mullerian hormone-AMH). Nws yog glycoprotein uas yog secreted los ntawm sustentacular hlwb nyob rau hauv cov txiv neej thaum lawv pib lawv morphological txawv nyob rau hauv teb rau SRY protein qhia. Qhov tsis muaj qhov tshwm sim no ua rau muaj kev loj hlob ntawm mullerian ducts mus rau hauv cov hlab ntsha, lub tsev menyuam, lub tsev menyuam, thiab sab sauv ntawm qhov chaw mos. Tsis tas li ntawd, kev hloov pauv hauv AMH noob lossis AMH cov noob receptors ua rau muaj kab mob hu ua persistent mullerian duct syndrome hauv cov txiv neej. Ntawm qhov tod tes, mullerian ducts anomalies ua rau lub tsev menyuam thiab qhov chaw mos agenises thiab duplication ntawm pliaj hlwb ntawm lub tsev menyuam thiab qhov chaw mos hauv pojniam.
Wolffian Duct yog dab tsi?
Wolffian duct yog ib lub cev ua ke uas tsim thaum lub sij hawm embryonic kev loj hlob ntawm tib neeg thiab lwm yam tsiaj. Nws ua rau cov txiv neej lub cev xeeb tub hu ua internal genitalia. Wolffian duct tseem hu ua mesonephric duct.
Daim duab 02: Kev sib deev sib txawv
Nyob rau hauv cov txiv neej, lub wolffian duct tsim mus rau hauv ib qho kev sib txuas ntawm nruab nrog cev ntawm cov ducts efferent ntawm testes thiab prostrate, uas yog epididymis, vas deferens, thiab seminal vesicle. Prostrate feem ntau yog tsim los ntawm urogenital sinus. Ntawm qhov tod tes, efferent ducts yog tsim los ntawm mesonephric tubules. Rau cov txheej txheem saum toj no, nws yog ib qho tseem ceeb uas cov wolffian ducts raug rau testosterone thaum lub sij hawm embryogenesis. Qhov no yog vim testosterone khi rau androgen receptor thiab activates nws, cuam tshuam intracellular signals tseem ceeb heev rau cov txheej txheem saum toj no. Ntxiv mus, Testosterone kuj hloov kho cov kev qhia ntawm ntau cov noob uas tseem ceeb heev rau kev loj hlob ntawm wolffian duct mus rau sab hauv genitalia. Hauv cov poj niam, qhov tsis muaj tshuaj tiv thaiv mullerian hormone secretion los ntawm sertoli hlwb regresses txoj kev loj hlob ntawm wolffian duct. Txawm li cas los xij, hauv cov txiv neej thiab poj niam, cov kab wolffian tau tsim rau hauv trigone ntawm lub zais zis.
Dab tsi yog qhov zoo sib xws ntawm Mullerian Duct thiab Wolffian Duct?
- Mullerian duct thiab wolffian duct tsim lub genitalia ntawm poj niam thiab txiv neej.
- Lawv yog ob lub embryonic qauv.
- Ob lub ducts muaj nyob rau hauv cov poj niam thiab cov txiv neej thaum lub sij hawm embryogenesis.
- Lawv txoj kev loj hlob mus rau hauv qhov chaw mos yog nruj tswj hwm los ntawm qhov muaj thiab tsis muaj cov tshuaj tiv thaiv mullerian.
- Lawv tseem ceeb heev rau kev yug me nyuam ntawm poj niam thiab txiv neej.
Qhov txawv ntawm Mullerian Duct thiab Wolffian Duct yog dab tsi?
Mullerian duct yog cov qauv embryonic uas tsim cov genitalia sab hauv ntawm poj niam, thaum Wolffian duct yog cov qauv embryonic uas tsim cov genitalia ntawm cov txiv neej. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm Mullerian duct thiab Wolffian duct.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm Mullerian duct thiab Wolffian duct nyob rau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Mullerian Duct vs Wolffian Duct
Mullerian duct thiab wolffian duct tsim lub genitalia ntawm poj niam thiab txiv neej. Lawv yog ob lub embryonic qauv uas yog ib qho tseem ceeb hauv kev ua qee qhov ntawm cov kab mob ntawm cov poj niam thiab txiv neej. Mullerian duct tsim cov genitalia sab hauv xws li cov hlab ntsha hauv plab, lub tsev menyuam, lub ncauj tsev menyuam, thiab sab sauv ntawm qhov chaw mos hauv cov poj niam, thaum wolffian duct tsim cov kab mob hauv nruab nrog cev xws li epididymis, vas deferens, thiab seminal vesicle hauv cov txiv neej. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm mullerian duct thiab wolffian duct.
