Ureter - ka 'ole a me ka mana o ka urinary'ōnaehana

Ureter - he lahilahi leki uea, a hoʻohuiʻia ka hakuʻala a me ka bladder ma i mimi, mai ka hakuʻala i koe o ka bladder. 'Ole a me ka hana ana o na ureters hōʻoia i ka maʻamau hana o ka urinary nenoaiu. Kēlā me kēia hakuʻala i ka ureter, i hele mai me kaʻaʻa puʻuwai pelvis, a komo i ka bladder. Ka lōʻihi o kēlā me kēia no ka ureter ma kahi o 30 knm, ke anawaena papa koa mai ka 4 a hiki i 7 mm o. ureter nui mea o ka nui i loko o urolithiasis. Pohaku nui ma mua o 4 mm o hiki ole ka 'elele i hele mai me ka papa o ka mimi ana ma ka bladder a me ka hopena i loko o ka ulu ana o kaʻaʻa puʻuwai colic.

Ureter: ka 'ole o ka abdominal a me ka pelvic māhele

Mai kaʻaʻa puʻuwai pelvis ureter mea i loko o ka ma lalo hema, a ma ka waena, a me pelvis, kahi e komo ai ka bladder, probodaya i kona pā pōhaku i loko o ka kēlā ao ao. Kēlā me kēia ureter hoomaopopo i abdominal a me ka pelvic hapa. Abdominal hapa o ka ureter ke aupuni 'o mua psoas Muscle. Ma mua o ka ureter akau hookaawale ae ua ilalo duodenum, ipu koko a me ke kumu o ka mesentery o ka uuku liʻiliʻi. Imua o ka hema o ka duodenal-jejunal flexure, vascular laulau a me ke kumu o ka mesentery o ka sigmoid AeXIeAaOIePEAaI.

Ke pelvic hapa o ka ureter kekahi, ma ke alo o ka iliac arteries a me aa koko. Ke anawaena o ka urethra ma keia wahi ua hou. I na kanaka, e hele ia ma mua o ka vas deferens, a ma lalo o ka hoaka o kaupoku o ka seminal vesicle empties i loko o ka bladder. Ke pelvic hapa o ka ureter i ka wahine i hoopuniia e nā kino: ka ureter holo ma ka lihi o ka uterine cervix a me ka ovary, komo i kaʻaoʻao bladder o ka vagina.

Kapa kūloko hapa o ka ureter, Aia i loko o ka pā o ka bladder.

Ureter: ka 'ole o ka pa

I ka pa o ka ureter, like hoʻi me kaʻaʻa puʻuwai pelvis a me na kiaha haku o ekolu mau papa: ka mea ma waho - connective'aʻaʻa loko kapa komo iā ia maloko malumalu epithelium me mucous glands a me ka meakino iloko olaila no nā papa o ka Muscle - lonikū a me ka hoʻopoepoe. Ureters musculature ua i pili i ka Muscle, ahu iho o ka bladder, a ua ālai 'aʻe pele o ka mimi, mai ka bladder i loko o ka ureter.

I wahi o ka hanana o ka ureter i loko o ka bladder i loko o kona pā mea he ahu iho la ka lonikū nāʻiʻo, pili loa aku i ka Muscle, ahu iho o ka bladder. Kēia ahu iho la ua 'Imi kāohi' ia paha nana e hoole ua eo mimi i loko o ka ureter. Ke alo o keia ahu iho hoʻohaiki ana i ka laha ana o maʻiʻaʻai mai ka bladder i loko o ka ureter, a loko o ka hakuʻala.

Ureter: ka 'oleʻae

Ke lumen o ka ureter loaʻa paha kekahi mau palena:

- ke kapu mua i loko o ka hoʻololi kahi pelvis i loko o ka ureter;

- i ka lua o ka ua aia ma ka palena ma waena o ka abdominal a me ka pelvic māhele'āina;

- i ke kolu o ka hou hiki ia ma kekahi hapa o ka pelvic hapa;

- ka ha kahi kokoke i ka constriction o ka bladder pa.

Ke alo o maoli constrictions o na ureters he nui lapaʻau mea hoʻomaoe. Ma kēia mau pauku apo la pōhaku exiting kaʻaʻa puʻuwai pelvis a me urinaryʻikena hele i loko o ke ala o ka bladder.

Ma ka papa o ka ureter i hou i ka anatomical kapu i physiological constriction, aʻikeʻia, a nalo i peristalsis.

Ureter: ka 'ole o ke koko a me ka lako innervation

Ka luna o ke koko, mai ka ureter loaa ana lala e holo ana mai ka hakuʻala, a me ka testicular a ovarian arteries. Na mawaena hapa ua lako ia me ke koko, mai ka ureteral lala e holo ana mai ka abdominal aorta a me ka iliac arteries. Na haʻahaʻa - mai ka vesical a me ka waena rectal arteries. koko ia lŘlŘ i loko o ka na iliac a me ka lumbar aa koko.

Innervation o ka ureter ua hana ma ka hahai ana i kekahi mau autonomic nā aʻalolo plexus. Na lala o ka vagus nā aʻalolo, a me ka pelvic splanchnic nā aʻalolo hoolako parasympathetic innervation.
