Kaikaice ventricle: Anatomy, aiki

Kaikaice ventricle, tare da sauran cavities a cikin kwakwalwa da cewa wani bangare ne na] aukacin tsarin a cikin abin da sayar da giya da aka kẽwayãwa. Su sadarwa tare da subarachnoid sarari na laka. A ciki surface daga cikin kogo aka liyi tare da ependyma. Su yi aiki ne domin tabbatar da mafi kyau duka kewayon matsa lamba a ciki da wajen kwakwalwa kuma laka.

Nau'in na kwakwalwa ventricles

Kaikaice ventricle (es) - karamin rami a babbar kwakwalwa da cewa samar da wani musamman kashin baya ruwa. Su suna dauke da most na na ramin zuciya tsarin. Wannan biyu samuwar, da kuma a can ne na musamman topography a gare shi.

A bar kaikaice ventricle, bisa al'ada, da aka kira na farko. A dama - na biyu. Su tsakaitã tare da juna da kuma m ilimin Halittar Jiki Tsarin, kuma ana shirya a kasa da bangarorin na epiphysis na midline. Kowane ventricle ne ya zama ruwan dare da kuma Kakakin jiki gaban, raya da kuma kasa. Monroe a kaikaice ventricles via ramuka haɗa ta uku ventricle.

The uku ventricle aka located tsakanin yankunan alhakin hangen nesa. Yana yana da wani zobe siffar da ta bango ne m al'amari dauke da autonomic ganglia. Bugu da kari ga kaikaice ventricles, wannan rami da aka haɗa a samar da ruwa igiyar.

A karo na hudu ventricle aka located tsakanin ƙananan cerebellum. A form yake kama da dala kuma ya kamata more daidai a kira da rhomboid fossa. Bugu da kari ga CSF a kasa na wannan rami da aka located mafi yawan nuclei na kashin baya jijiyoyi.

jijiyoyin bugun gini plexus

Kaikaice ventricle (es) ne kawai partially da hannu a cikin irin wannan ra'ayi kamar yadda jijiyoyin bugun gini plexus. Mafi yawan waɗannan Tsarin suna located a cikin rufi daga cikin uku da na hudu ventricles. Su suke da alhakin mafi yawan samar da cerebrospinal ruwa. Baya daga gare su, wannan aiki aka yi kai tsaye ga m nama, kazalika da ependyma da yake rufe da ciki na ventricles na kwakwalwa.

Morphologically, jijiyoyin bugun gini plexus ne outgrowths pial ɗora Kwatancen cikin ventricles. Waje wadannan protrusions an rufe tare da cubic takamaiman choroid epithelium.

Ependimotsity

A kaikaice ventricles na kwakwalwa suna liyi da musamman masana'anta a ciki, wanda zai iya samar da duka biyu CSF da sha da shi. Wannan taimaka wajen ci gaba da mafi kyau duka adadin ruwa a cikin kogo, da kuma dagagge intracranial matsa lamba.

A matsanancin surface daga gare an rufe tare da manyan yawan microvilli, suka taimake inganta kashin baya ruwa, kazalika da ta sha. Waje ependyma located Kolmer Kwayoyin, wanda suna dauke musamman irin macrophages suke iya motsi ta hanyar jiki.

Ta hanyar mahara kananan gibba a cikin ginshiki membrane a cikin kogo na ventricles epindemotsitov exuded jini jini. Don shi ne kara sunadaran samar da epithelium kanta ciki cavities na kwakwalwa Kwayoyin, don haka shi dai itace sayar da giya.

Wannan rikitarwa tsarin zama dole domin ya hana a cikin cerebrospinal ruwa na na rayuwa kayayyakin, da miyagun kwayoyi da sauran guba abubuwa.

kashin baya ruwa

A kullum na kaikaice ventricles - samar bene lita na sayar da giya da rana, amma daya kawai ɗari da arba'in da milliliters wannan adadin da aka ci gaba da kẽwayãwa a subarachnoid sarari. Duk da cewa dalilin da cerebrospinal ruwa ne jini jini, suna da gagarumin bambance-bambance a cikin yawan Wutan da kuma gina jiki. A farko - shi ne muhimmanci mafi girma, kuma na biyu - a kasa. Bugu da ƙari kuma, a cikin giya kullum ba a qananan adadin lymphocytes. Reabsorption na cerebrospinal ruwa na faruwa a cikin wuri na gabatarwar da jijiyoyin bugun gini plexus.

Ware wadannan CSF ayyuka:

- detoxification (rayuwa samfurin kai).

- dakatar (a lokacin tafiya, da dama, kaifi jũya).

- samuwar wani harsashi a kusa da hydrostatic abubuwa na juyayi tsarin.

- rike m abun da ke ciki na taya a tsakiya m tsarin.

- kai (kai na hormones da kuma wasu magunguna).
