Taw qhia
Oxytocin, yog peptide hormone thiab neuropeptide, ib hom tshuaj uterine contractile, uas tuaj yeem muab rho tawm los ntawm cov tsiaj tom qab pituitary los yog hluavtaws tshuaj.Yog hais tias synthesize los ntawm cov tshuaj uas tsis muaj vasopressin thiab tsis muaj zog.
Nws muaj peev xwm xaiv excite lub uterine smooth nqaij thiab ntxiv dag zog rau nws contraction.Lub tsev menyuam muaj hnub nyoog yog qhov nkag siab tshaj plaws rau oxytocin vim tias muaj cov tshuaj estrogen ntau ntxiv.Lub tsev menyuam tsis paub qab hau tsis muaj kev cuam tshuam rau cov khoom no.Lub uterine teb rau oxytocin yog tsawg nyob rau hauv thaum ntxov los yog nruab nrab lub peb hlis ntuj ntawm cev xeeb tub, tab sis maj mam nce nyob rau hauv lub lig lub peb hlis ntuj ntawm cev xeeb tub, thiab mus txog rau lub siab tshaj plaws ua ntej yug.
Ib koob tshuaj me me tuaj yeem ntxiv dag zog rau lub cev sib luag ntawm cov leeg nqaij hauv qab ntawm lub tsev menyuam, ntxiv dag zog rau nws cov contractility, ua kom lub zog sib nqus, thiab tswj cov polarity thiab symmetry zoo ib yam li cov khoom xa tuaj.Yog li ntawd, nws yog siv nyob rau hauv kev kho mob rau induce zog los yog oxytocia.
Ib koob tshuaj loj ua rau cov leeg nqaij uterine cog lus hauv tetanic.Nws yog siv nyob rau hauv kev kho mob rau compress cov hlab ntsha ntawm cov leeg nqaij fibers, tiv thaiv postpartum hemorrhage thiab tsis tiav postpartum involution.Nws txhawb kev lactation, txo qis cov kab mob mammary, thiab txhawb cov kua mis tawm ntawm lub mis.Txawm li cas los xij, nws tsis tuaj yeem nce qhov tso tawm ntawm cov mis nyuj, tab sis tuaj yeem txhawb nqa cov kua mis tawm xwb.
Oxytocin feem ntau ua ke nrog kev npaj ergot los kho cov ntshav tom qab yug menyuam.Nws yog tsuas yog siv rau induced ua hauj lwm nyob rau hauv lub cev xeeb tub lig thiab qeeb zog los ntawm uterine atony thaum lub sij hawm cev xeeb tub.Nws kuj tseem siv rau kev kuaj oxytocin rhiab heev thiab pab hauv kev tso kua mis tom qab yug menyuam.
Oxytocin raug tso tawm rau hauv cov hlab ntsha raws li cov tshuaj hormones hauv kev teb rau kev sib deev thiab thaum ua haujlwm.Nws kuj muaj nyob rau hauv daim ntawv tshuaj.Nyob rau hauv ob daim ntawv, oxytocin stimulates uterine contractions kom ceev cov txheej txheem ntawm kev yug menyuam.Kev tsim khoom thiab kev tso tawm ntawm oxytocin yog tswj los ntawm kev tawm tswv yim zoo, qhov twg nws qhov kev tso tawm thawj zaug txhawb kev tsim khoom thiab tso tawm cov oxytocin ntxiv.
