Ventricle lateral: anatomy, umsebenzi

ventricle lateral, kunye nezinye ukuqanda ingqondo oyinxalenye yenkqubo iyonke apho utywala ujikeleziswe. Ethetha kwisithuba subarachnoid ye umnqonqo. Umphezulu engaphakathi lweHo- igcwele ependyma. umsebenzi wawo kukugcina uluhlu ngokupheleleyo kuxinzelelo ngaphakathi nangaphandle yobuchopho kunye umnqonqo.

Types of ventricles ingqondo

ventricle lateral (es) - umngxuma encinane ubuchopho enkulu ukuba bavelise ethile ulwelo spinal. Bona zithathwa inkulu kwenkqubo ventricular. Le ukusekwa pair, kwaye kukho mphandle ethile kuye.

Le ventricle lateral ngasekhohlo, ngokwesithethe, kuthiwa kuqala. Ilungelo - yesibini. Bathe macala kunye nezinye kunye ezikufutshane izakhiwo yokwakheka ngamnye, yaye zicwangciswe ngezantsi emacaleni epiphysis ye osembindini. ventricle nganye ayinabantu nophondo umzimba ngaphambili, ngasemva kunye ezantsi. Monroe ventricles lateral nge imingxuma eqhagamshelwe ventricle wesithathu.

Le ventricle wesithathu ifumaneka phakathi kwiindawo anoxanduva umbono. It has a imilo ring nodonga lwawo na umcimbi grey equlethe ganglia yawo. Ukongeza ventricles osecaleni, le kwisisu oludityaniswe intambo yonikezelo lwamanzi.

Le ventricle yesine ibekwe phakathi kwiCerebellum asezantsi. Xa uhlobo kufana iphiramidi kwaye kufuneka ngokucokisekileyo ngakumbi ngokuthi fossa rhomboid. Ukongeza CSF emazantsi kulo mhadi kubekwe uninzi eziba kwimithambo- lialio.

plexus olujikeleza

ventricle lateral (es) engagqibekanga kuphela inxaxheba ingqiqo njengoko plexus nemithambo hlobo. Uninzi lwezi zakhiwo ibekwe eluphahleni ventricles yesithathu neyesine. Abanoxanduva uninzi imveliso ulwelo fluid. Ngaphandle kwabo, lo msebenzi wenziwa ngqo izihlunu luvo, kwakunye ependyma esigquma ngaphakathi ventricles ingqondo.

Morphologically, plexus nemithambo ezi outgrowths pial zilayishwe kungena ventricles. Ngaphandle kwezi lunamaqoqo zizele cc ethile epithelium choroid.

Ependimotsity

Le ventricles lateral zobuchopho ilandelelanisiwe kunye nelaphu ngaphakathi, nto leyo ukuvelisa zombini CSF kunye ukukuqonda. Oku kunceda ukuba ugcine imali kangangoko ulwelo lweHo-, yaye esinyusiweyo ingcinezelo intracranial.

zeeseli epithelial babe organelles ezininzi kunye kwahlelwa enkulu. Umphezulu engaphandle layo ligutyungelwe inani elikhulu microvilli, zinceda ukukhuthaza fluid spinal, ngokunjalo ukufunxeka kwayo. ependyma Ngaphandle ibekwe iiseli Kolmer, apho ingqalelo uhlobo olulodwa macrophage ukuba ziyakwazi ezihamba umzimba.

Ngokusebenzisa izikhewu ezincinane ezininzi kwigumbi elingaphantsi inwebu ukuya em- le epindemotsitov ventricles exuded plasma yegazi. Apho iiproteni eziveliswa epithelium ngokwawo angabi nemingxuma zangaphakathi neeseli zobuchopho wongezelela, ngoko kuvela utywala.

umqobo igazi-nobuchopho

akhande angaphakathi lomzimba kuba uphondo ventricles osecaleni okanye igazi-ingqondo umqobo gematolikvorny. Le yingqokelela amalaphu, zicwangciswe ngendlela ethile;

- kukho icytoplasm of capillary endothelium;

- tissue equlathe macrophage nokuqina;

- endothelial kwendlu ndizayo;

- iiseli ependymal;

- kwesakhiwo ndizayo ependyma.

Esi sakhiwo nzima kuyimfuneko ukuze kuthintelwe kulwelo cerebrospinal iimveliso pathways, iziyobisi kunye nezinye izinto eziyityhefu.

fluid spinal

Ummiselo we ventricles osecaleni - iilitha omgangatho imveliso zotywala ngosuku, kodwa mnye kuphela elinamanci mane mililitha eli xabiso gqolo kusasazwa kwisithuba subarachnoid. Ngaphandle kwento yokuba isiseko ulwelo lwe-cerebrospinal na plasma yegazi, bona babe umahluko kakhulu inani electrolytes kunye protini. Lokuqala - ngokuphawulekayo aphezulu, kwaye eyesibini - ngezantsi. Ngaphezu koko, kule utywala iqhele umnikelo wokudla lymphocyte imali engephi. Reabsorption kolwelo fluid kwenzeka endaweni ukuqaliswa plexus nemithambo.

Ukwabela imisebenzi CSF ilandelayo:

- detoxification (izithuthi imveliso metabolic);

- ukumiswa (ngexesha ukuhamba, uwe, ubhekisa ezibukhali);

- ukuyilwa kwiqokobhe ngeenxa zonke izinto hydrostatic-luvo;

- nokugcina nokwakheka rhoqo ulwelo kwinkqubo luvo;

- zothutho (uthutho hormone amayeza athile).

zezifo ventricles

Xa elinye ventricle osecaleni (okanye zombini) ukuvelisa fluid ngaphezu ukubamba uqala imeko zophendlo lwezifo njengoko hydrocephalus. Umthamo lwangaphakathi ventricles yaba yintsimi, ngokuveza ijwabu ebuchotsheni. Ngamanye amaxesha oku kukhokelela ischemia vuhlayiseki kunye necrosis.

Kwiintsana kunye nabantwana abancinane iimpawu zesi sifo ezinomlinganiselo elibi eli cranium xa kuthelekiswa yobuso, ewayo fontanelle, umntwana ixhala elimsulwa ajike ngabandayo. Xa abadala, kukho izikhalazo intloko ebuhlungu, iintlungu emehlweni, isicaphucaphu nokugabha.

Moshilongo usebenzisa ubuchule neuroimaging: livakale Imagnethi okanye ngekhompyutha unyango Itomography. ukubhaqwa kunye nonyango lwesi sifo kuthintela inani elikhulu yeengxaki nokulondoloza amathuba ubomi obuqhelekileyo.
