Ureter - isakhiwo kunye nemisebenzi nkqubo womchamo

Ureter - a duct obhityileyo, leyo inxulumanisa wezintso kwaye esinyini apho umchamo amagqabi ukusuka kidney ukuya lwesinye. Ubume kunye umsebenzi ureters ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo womchamo. Nganye kidney abe ureter, apho uya ukusuka isinqe sezintso kwaye engena isinye. Ubude nganye ureter malunga-30 cm, lo ubukhulu isusela 4 ukuya kowe-7 mm. ubukhulu ureter kubaluleke kakhulu urolithiasis. Stones ezinkulu kwe-4 mm akakwazi ngokukhululekileyo niphuma langoku umchamo esinyini kwaye kukhokelela kuphuhliso yokulunywa kwezintso.

Ureter: isakhiwo esiswini kunye iindawo zangasese

Ukusuka sezintso isinqe ureter na kwicala phantsi, phakathi kunye isinqe, apho ingena esinyini, probodaya udonga yakhe kwicala elibhalwe ngokumileyo. ureter nganye ukwahlula yinxalenye esiswini kunye zangasese. inxalenye besisu ye ureter ibekwe yesihlunu phambi psoas. Phambi kokuba ureter ekunene siyahlukana duodenum phantsi, imithambo yegazi kunye kwisiseko mesentery ye emathunjini amancinci. Silindele osekhohlo duodenal-jejunal flexure, inyanda nemithambo kunye kwisiseko mesentery le colon sigmoid.

Inxalenye zangasese le ureter Kwathi phambi kwemithambo iliac ngemithambo. Ubukhulu be urethra kule ngenxenye iingqameko. Ngabantu, udlula phambi Umbobho yobudoda kwaye ngezantsi kwipali aphezulu vesicle ZakwaLizwi ungena lwesinye. Inxalenye zangasese le ureter amabhinqa singqongwe ngamanye amaqumrhu: i ureter ubaleka ezigudle wesibeleko zesibeleko kunye maqanda, engena icala esinyini kwinxenye yelungu lobufazi.

Ebizwa ngokuba isabelo intramural le ureter, ibekwe ngaphakathi eludongeni lwesinye.

Ureter: isakhiwo eludongeni

Udonga ureter, kwakunye isinqe kwezintso kunye neendebe yakhiwa ngeengcamba ezintathu: engaphandle - kwizicwili yangaphakathi kugalelwe ngaphakathi epithelium ethutyana amadlala yangaphakathi kunye neliphakathi ebandakanya lamanqanaba ezimbini zihlunu - longitudinal and setyhula. Ureters musculature akukho edibene umaleko kwezihlunu lwesinye yesininzi kwaye uthintele nokusetyenziswa kwemali reverse umchamo ukusuka esinyini ukuya ureter.

Xa indawo elivela kuzo ureter ukuya esinyini eludongeni yayo yi umaleko izihlunu longitudinal, ngokusondeleyo ukuya umaleko kwezihlunu lwesinye. Lo maleko aza kuthintela reverse Isikolo umchamo kungena ureter. Ubukho kwale maleko enokuthintela ukosuleleka ukusuka esinyini ukuya ureter kwaye kungena kwizintso.

Ureter: kugqitywe isakhiwo

Le mithambo ye ureter iye izithintelo ezininzi:

- I isithintelo sokuqala inguqu ndawo isinqe kungena ureter;

- wesibini ukwakweli umda phakathi esiswini kunye kummandla zangasese;

- ukuvala wesithathu ibe nayiphi na inxalenye isabelo zangasese;

- yesine ifumaneka kufuphi constriction lo lwesinye.

Ukubakho constrictions zendalo ureters kuneziphumo ezibalulekileyo clinical. Kwezi ziqendu wanamathela amawa kokuphuma isinqe kwezintso kunye wokuchama abahambahambayo yangoku kwicala lwesinye.

Ekuhambeni kwe ureter ukongeza kwizithintelo yokwakheka zezi constriction komzimba, ezibonakala kwaye shwaka ngexesha peristalsis.

Ureter: isakhiwo unikezelo igazi innervation

Inxalenye engentla igazi ukusuka ureter ifumana amasebe elandisiweyo ukususela kwizintso, kunye wamatyhalarha okanye imithambo ovarian. Indawo ephakathi inikezelwa igazi amasebe ureteral elandisiweyo ukususela esiswini aorta kunye iliac imithambo. Kumazantsi - ukusuka kwemithambo vesical kunye ophakathi efakwa. ukugeleza kwegazi lwenzeka kwi lwangaphakathi iliac kunye empontshwa umthambo.

Innervation le ureter lwenziwa ngokulandela kwenzwa yawo embalwa plexus. Amasebe luvo vagus kunye imithambo zangasese splanchnic zibonelela innervation parasympathetic.
