Esịtidem akụkụ. ikensi

Ikensi bụ distal colon. Ọ na-emi odude na azụ pelvic ebe na-agwụ na crotch ngalaba. Ikensi nwere ogologo iri na ise - iri na isi sentimita. Elu Ókè ya dị na akwụkwọ ozi na elu onu nke sacral vertebra III.

Ikensi. Structure.

The ngwa nwere ihe abụọ bends: na ntopute azụ (sacrum) na ntopute na-atụ (crotch). Ókè n'etiti pelvic na perineal ngalaba na-ewe ebe na ebe nke na-ekekọta gbasara ike levator uru. Pelvic ngwa Division, emi odude ke pelvic mpaghara, nwere ampullar (enwe na sacrum larịị mgbasawanye nke ampoules) na nadampulyarny iche. The crotch ngalaba bụ ọtụtụ narrower. Agafe crotch, ọ Nleta gbasara ike kanaal, emeghe n'azụ oghere. Ikensi ka lumen forms nchawa nsogbu transversely. Jupụta lumen nwere oval udi.

The elu akụkụ nwere zita ikensi peritoneum mkpuchi nke nta nke nta na-efu n'ebe ala. Na mpaghara IV sacral vertebra peritoneal cover na-nọgidere na-enwe na na ya n'ihu mgbidi. Akwara shei ahụ na-anọchi anya dị ka abụọ (n'ime okirikiri na elu longitudinal) n'ígwé. N'ime oyi akwa a kpụrụ na ndim nke gbasara ike kanaal òkè - ịsụ (esịtidem) gbasara ike sphincter. The mpụta oyi akwa nwere a ịkpa ákwà esiwọrọ gbasara ike levator muscle. Aka ike (elu) sphincter bụ annular muscle, nke ndị mejupụtara subcutaneous na miri n'elu akụkụ.

The mucosa ampullar ngalaba na-arụpụta abụọ - atọ transverse na helical N'ezie nke folds. The gbasara ike kanaal a kpụrụ site na asatọ - iri gbasara ike na ogidi (longitudinal folds), na isi nke nke mee nke ezigbo muscle na connective anụ ahụ. The mucosa bụ sebaceous glands na naanị lymphoid nodules. Na ókè-ala nke anụ ahụ na mucous ndokwa ntutu follicles na ajirija glands. Gbasara ike sinuses (recesses n'etiti ogidi) na-ejedebeghị na flaps na-etolite na rectal-gbasara usoro. Na mpaghara a na e nwere venous plexus. Ebe a, a otu-oyi akwa cylindrical mucous epithelium aghọ stratified epithelium ewepụghị udi.

The mucosa elu mmiri ike, nke na-akpata na-rectal ochichi nke ọgwụ ọjọọ na oke mmiri.
