Isinye sesinye sezitho ezibalulekile zesistimu yokukhipha indle emzimbeni womuntu. Nakuba izinso zinesibopho sokukhiqiza umchamo, isinye sinesibopho sokuwugcina nokuxoshwa kwawo kokugcina. Isinye sitholakala engxenyeni engezansi yesisu, endaweni ye-pubic - ngenxa yalokhu kucasha okuqondile, singazivikela ekulimaleni ngamathambo e-pelvic azungezile. Uma esinyeni singenalutho, sithatha isimo sefaneli enwebekayo phezulu bese sincipha ngezansi, kanti uma sigcwele siba yindilinga. Umthamo wesinye unqunywa kakhulu yi-anatomy, kodwa ngokuvamile umthamo waso uphakathi kwamalitha angu-0,4 no-0,6.
Umchamo wesinye - i-anatomy
Ukwakheka kwesinye isinye ibonisa ukugcinwa kwayo kwangaphakathi kanye nezingqimba eziningi zokuzivikela, ezivikela ukulimala, isibonelo emathanjeni e-pelvic. Yakhiwe ikakhulukazi imisipha ebushelelezi, izicubu ezixhumeneyo nemithambo yegazi, ngokuma kwayo sihlukanisa phezulu, i-shaft, phansi nentamo. Izindonga zesinye zinezingqimba ezintathu - ungqimba lokuqala lokuvikela, olungaphandle, okuthiwa ulwelwesi lwe-serous, ungqimba oluphakathi nendawo - phakathi kwezingxenye zangaphandle nezingaphakathi - okungukuthi ungqimba oluphakathi (izicubu zemisipha) kanye nolwelwesi lwangaphakathi. , okungukuthi i-serous membrane. isici esibalulekile ukwakheka kwesinye iwumgogodla walo eliwudalayo imisipha ye-detrusor ukuvumela izinguquko zamahhala zesimo sesitho kuzo zonke izinhlangothi. Ezansi esinyeni kune-urethra, egcina ikhipha umchamo emzimbeni womuntu. Kwabesilisa, isimo sinzima kakhulu kulokhu, ngoba i-anatomy yesinye ithatha ukuthi ikhoyili idlula phakathi nendawo ye-prostate gland, okuthiwa yi-prostate. Lona wumsuka wezinkinga eziningi kule ndawo mayelana nokuchama. Kaningi kukhona ukwanda kwendlala futhi okubangelwa yilokhu ukucindezela kukhoyili. Lokhu kuvame ukuphumela ekuncipheni komthamo wokugeleza, futhi ezimeni ezibucayi kakhulu, ukungakwazi ukuchama ngokuphelele. Isici esibaluleke kakhulu sesakhiwo sesinye somchamo yi-sphincter ye-urethral, ngoba sibonga ukuthi kungenzeka ukulawula ukuphuma komchamo. Kuyimisipha ehlala igcina ukungezwani, ngenxa yokuthi ukuvulwa kwe-urethra kuvaliwe ngesikhathi sokugcinwa komchamo. Indima yayo iwusizo ikakhulukazi ezimweni lapho kukhona ukwanda okungazelelwe kokucindezela endaweni yesisu - ngisho nangesikhathi sokuhleka, ukukhwehlela, ukuthunga. I-Sphincter ingavimbela ukuphuma komchamo okungafunwa ngokucindezelwa kwemvelo.
Umchamo wesinye – ungahlali ngaphandle kwawo
Umzimba womuntu usebenza ngendlela yokuthi ngokwemvelo unqwabelane nomchamo bese uyawukhipha. Yisitho esiza ekufezeni le misebenzi esinyeni. Ikuvumela ukuthi ugcine uketshezi oluhlungiwe, futhi ngiyabonga i-sphincter ukuyigcina ilawulwa. Ekugcineni, kuwumsebenzi esinyeni kubangela ukuthi umchamo ukhishwe. Izikhungo eziqondisa le misebenzi zitholakala ohlelweni lwezinzwa - ku-cerebral cortex, intambo yomgogodla, ku-peripheral ganglia. Yilapho amasignali engena khona isinye sigcwale. Amandla esinyeni ngoba akunamkhawulo. Uma uketshezi luwugcwalisa ku-1/3, khona-ke amasignali ageleza asuka kuma-receptors wezindonga zesinye aye ngqo ku-cerebral cortex, okubonisa isidingo sokuzikhulula. Uma umuntu ngaleso sikhathi engasabeli futhi engachami, lezi zimpawu ziba namandla, okuphumela ekubeni nomuzwa wokufisa okukhulu, ngezinye izikhathi ngisho nokubuhlungu. Ngesikhathi esifanayo, umsebenzi ucushiwe ngalesi sikhathi ama-sphincters e-urethraokuvimbela ukuphuma komchamo okungafunwa. Uma ukuzikhulula ekugcineni kungenzeka, izikhungo zemizwa ziyayeka ukuthumela izimpawu ezivimbayo ezishaqisayo, i-sphincter ukuxhuga nomchamo uyakhishwa. Ngemva kokukhishwa kwamathumbu sekuqediwe, izitho ziyafinyela futhi, zilungiselela ukuqoqwa komchamo esinyeni.
