Ofananira ventricle: thunthu, ntchito

Ofananira ventricle, pamodzi ndi cavities ena mu ubongo ndi mbali ya chitetezo cha chonse chimene mowa ndi akufalitsa. Polankhulana ndi danga subarachnoid wa chingwe msana. Pamwamba lamkati la M'mimbamo ndi wodzaza ndi ependyma. Ntchito yawo ndi kukhalabe mulingo woyenera osiyanasiyana kuthamanga mkati ndi kunja ubongo ndi msana.

Mitundu ya ventricles ubongo

Ofananira ventricle (es) - ndi M'mimbamo yaing'ono ubongo lalikulu kutulutsa makamaka msana madzimadzi. Amaonedwa yaikulu ya dongosolo yamitsempha yamagazi. Izi mapangidwe awiri, ndipo pali zimachititsa chilumbachi yeniyeni iye.

Anachoka lateral ventricle, malingana ndi mwambo, amatchedwa choyamba. A bwino - chachiwiri. Iwo symmetrical ndi mzake ndi moyandikana nyumba anatomical, ndipo anakonza pansipa mbali ya epiphysis wa midline lapansi. Aliyense ventricle ndi akutali ndi nyanga thupi kutsogolo, kumbuyo ndi pansi. Monroe lateral ventricles kudzera mabowo olumikizidwa kwa ventricle lachitatu.

The ventricle lachitatu lili pakati pa madera udindo masomphenya. Iwo ali mphete mawonekedwe ndi mpanda wake ndi imvi nkhani munali autonomic ganglia. Kuwonjezera pa ventricles lateral, M'mimbamo izi chikugwirizana ndi madzi chingwe.

The ventricle lachinayi limene lili pakati pa cerebellum m'munsi. Mu mawonekedwe izo akufanana piramidi ndipo ayenera molondola kwambiri kutchedwa fossa rhomboid. Kuwonjezera pa CSF pansi pa dzenje ili ambiri a mtima wa misempha msana.

mtima plexus

Ofananira ventricle (es) ndi pang'ono kokha nawo malingaliro monga plexus mtima. Ambiri a nyumba izi zili pa ntsoyi ya ventricles wachitatu ndi wachinayi. Iwo ali ndi udindo ambiri a ulimi wa madzimadzi cerebrospinal. Kupatula iwo, ntchito imeneyi imagwiridwa mwachindunji kwa minofu mantha, komanso ependyma okuta mkati mwa ventricles ubongo.

Morphologically, plexus mtima ndi outgrowths pial yodzaza mu ventricles lapansi. Kunja protrusions izi okutidwa ndi kiyubiki yeniyeni choroid epithelium.

Ependimotsity

The ventricles lateral ubongo Ng'ona ndi nsalu wapadera mkati, zomwe zingabweretse onse mowa ndi kuyamwa izo. Izi zimathandiza kudziwa mulingo woyenera kuchuluka kwa madzi mu M'mimbamo, ndi kukwezeka kuthamanga intracranial.

maselo zaminyewa ndi organelles ambiri ndi phata lalikulu. Pamwamba kunja kwake yokutidwa ndi ambiri microvilli, amathandiza kulimbikitsa msana madzimadzi, komanso mayamwidwe ake. Kunja ependyma ili Kolmer maselo, amene ankaona mtundu wapadera wa macrophages kuti angathe kusamukira ku thupi lonse.

Kudzera mipata angapo ang'onoang'ono chapansi Kakhungu kuti patsekeke wa ventricles epindemotsitov exuded madzi a m'magazi. Kuti izo mapulotini opangidwa ndi epithelium yokha cavities m'maselo ubongo, ndipo likukhalira mowa.

magazi ubongo chotchinga

akalowa ake lamkati la thupi ndi kupanga nyanga ya ventricles ndi lateral kapena magazi ubongo chotchinga gematolikvorny. Ndi mndandanda wa nsalu, anakonza mu dongosolo makamaka:

- cytoplasm cha capillary endothelium;

- connective minofu munali macrophages;

- za indofeliyamu chapansi nembanemba;

- ependymal maselo;

- chapansi Kakhungu ependyma.

Mlatho zovuta n'kofunika pofuna kupewa mu madzimadzi cerebrospinal katundu kagayidwe kachakudya, mankhwala ndi zinthu zina za poizoni.

madzimadzi msana

Ponseponse ya ventricles lateral - kupanga pansi malita a mowa patsiku, koma Botolo chimodzi chokha zana ndi makumi anai a kuchuluka izi mosalekeza akufalitsa danga subarachnoid. Ngakhale kuti maziko madzimadzi cerebrospinal ndi madzi a m'magazi, ali kusiyana kwambiri chiwerengero cha electrolytes ndi mapuloteni. The choyamba - ndi apamwamba kwambiri, ndipo chachiwiri - pansipa. Komanso, mu mowa ndi zambiri pano mu lymphocytes zazing'ono ndalama. Reabsorption wa madzimadzi cerebrospinal amapezeka mu malo oyamba a plexus mtima.

Kuonetsetsa otsatirawa ntchito CSF:

- detoxification (kagayidwe kachakudya chotuluka zoyendera);

- kuyimitsidwa (pa kuyenda, akugwa, ankasinthana lakuthwa);

- mapangidwe chipolopolo padziko zinthu hydrostatic ya ubongo;

- kukhalabe zikuchokera zonse zakumwa mu chapakati mantha dongosolo;

- zoyendera (zoyendera mahomoni ndi mankhwala ena).

matenda a ventricles ndi

Pamene mmodzi lateral ventricle (kapena onse) kubala madzimadzi kuposa akhoza kuyamwa akufotokozera chikhalidwe pathological monga hydrocephalus. Voliyumu mkati mwa ventricles pang'onopang'ono kuchuluka, compressing ubongo minofu. Nthawi zina zimenezi zimapangitsa kuti ischemia sizingasinthe ndipo necrosis.

Makanda ndi ana zizindikiro za matenda ndi akanagwiritsa kukula kwa cranium poyerekeza ndi nkhope, oumbidwa fontanelle, causeless nkhawa mwana kutembenukira mu mphwayi. Akuluakulu, pali madandaulo a kupweteka kwa mutu, kupweteka maso, kunyansidwa ndi kusanza.

Pakuti matenda pogwiritsa ntchito maluso neuroimaging: maginito kumveka kapena yopangidwa tomography mankhwala. kudziwika oyambirira ndi mankhwala a matenda chindiletsa ambiri a matendawo ndi kusunga kuthekera kwa munthu wabwinobwino.
