Lateral ventricle: human anatomy, mosebetsi

Lateral ventricle, hammoho le cavities ba bang ka boko ba seo e leng karolo ea tsamaiso ka kakaretso eo ho eona joala e ajoa. Ba buisana le sebaka subarachnoid ea thapo lesapo la mokokotlo. Holim 'le ka hare la cavity e lined ka ependyma. mosebetsi oa bona ke ho boloka homolog fapaneng ya khatello e ka hare le ka ntle ya boko le lesapong la mokokotlo.

Types of ventricles boko

Lateral ventricle (fi) - e cavity nyane ka boko o moholo o hlahisa se itseng lesapo la mokokotlo mokelikeli. Ba li nkoa e kholo ka ho fetisisa ea tsamaiso ventricular. Ena sebopeho para, 'me ho na le sebopeho sa naha e itseng bakeng sa hae.

Le letšehali lateral ventricle, ho ea ka neano, o bitsoa pele. A e nepahetseng - bobeli. Ba ditshwani le mong ho e mong le haufi dibopeho anatomical, 'me ba lokisetsa tlase mahlakoreng a epiphysis tsa midline ena. E mong le e ventricle e ka thōko 'me lenaka le' mele ka pele, ka morao le ka tlase. Monroe lateral ventricles dessyecik mekoti amanang ho ventricle boraro.

The ventricle boraro e teng pakeng tsa libaka tse nang le boikarabelo bakeng sa pono. E na le lesale sebopeho le leboteng lona ke ea bohlooho taba e nang le autonomic ganglia. , Ho phaella ho ventricles lateral, cavity ena e amana ho phepelo ea metsi khoele.

The ventricle bone e teng pakeng tsa cerebellum tlaase. Foromo e tšoana le phiramiti le e lokela ho ka tsela e nepahetseng ho feta ho bitsoa fossa rhomboid. , Ho phaella ho CSF ka tlase ka sekoting sena e teng ho fetisisa ea nuclei ba methapo lesapo la mokokotlo.

vascular akira theo gun

Lateral ventricle (fi) e mokhoa o sa fellang feela ho akarelletsa khopolo e kang akira theo gun vascular. Boholo ba mehaho e tsena ba sebakeng marulelong ea ventricles boraro le ea bone. Ba na le boikarabelo ba ho fetisisa ea ho hlahisa mokelikeli cerebrospinal. Ntle ho tsona, mosebetsi ona o etsoa ka ho toba ho ea dinama tse nyenyane tse ea methapo, hammoho le ependyma hore koahela ka hare tsa ventricles ea boko.

Morphologically, akira theo gun vascular ke a hlomelang a manyenyane pial laela ka ventricles ena. Kantle protrusions tsena tse koahetsoeng ka dikubita itseng choroid epithelium.

Ependimotsity

The ventricles lateral ea boko ba lined le lesela khethehileng ka hare, e leng se ka hlahisa bobeli CSF le monya eona. Sena se thusa ho boloka homolog palo ea mokelikeli ka cavity, 'me phahameng khatello ea intracranial.

lisele tse epithelial na organelles tse ngata le khubung kgolo. Holim 'ka ntle ya lona e koahetsoe le palo e khōlō ea microvilli, ba thusa ho kgothaletsa lesapo la mokokotlo mokelikeli, hammoho le absorption lona. Kantle ependyma teng Kolmer lisele tse, e leng li nkoa e le mofuta o khethehileng oa macrophages hore ba ka khona ho fallela ka 'mele.

Ka likheo tse ngata tse nyenyane ka kamoreng e ka tlaase lera ka cavity tsa ventricles epindemotsitov exuded lero la mali mali. Ho e eketsa lihaha-'mele tse hlahisoang ke ho epithelium ka boeona cavities hare ea lisele tsa boko, 'me gore e tle e fellang kateng le joala.

lera lona ka hare tsa 'mele le ho theha lenaka la ventricles ea lateral kapa mali-boko mokoallo gematolikvorny. Ke pokello ea masela, o ile a lokisetsa ka odara ho khetheha:

- cytoplasm tsa capillary endothelium;

- connective dinama tse nyenyane tse nang le macrophages;

- endothelial kamoreng e ka tlaase lera;

- ependymal lisele tse;

- kamoreng e ka tlaase lera ependyma.

Ena sebopeho rarahaneng e hlokahala e le hore ho thibela ho mokelikeli cerebrospinal tsa lihlahisoa tshilong ya dijo, lithethefatsi le lintho tse ling tse nang le chefo.

mokelikeli lesapo la mokokotlo

Le ntho e tloaelehileng ea ventricles lateral - tlhahiso ea mokatong dilitara tse joala ka letsatsi, empa dimililitha le 'ngoe feela tse lekholo le mashome a mane ba palo ena e sa khaotse a ajoa ka sebaka sa subarachnoid. Ho sa tsotellehe 'nete ea hore motheo bakeng sa mokelikeli cerebrospinal ke mali lero la mali, ba na le ho se tšoane bohlokoa palong ea electrolyte le protheine. Pele - e haholo e phahameng, 'me ea bobeli - tlase. Ho feta moo, joala bo sa ka tsela e tloaelehileng le teng ka lymphocytes nyenyane palo. Reabsorption mokelikeli cerebrospinal le hlaha sebakeng sa selelekela tsa akira theo gun vascular.

Abelwang karolo ya tse latelang mesebetsi CSF:

- detoxification (tshilong ya dijo ka sehlahisoa lipalangoang);

- sebopeho sa khetla pota thepa ea motheo e hydrostatic ea tsamaiso ea methapo ea kutlo;

- ho lula sebopeho kamehla sephalli e tsamaiso ea methapo e bohareng;

- ho tsamaisa (lipalangoang tsa li-hormone le meriana e itseng).

mafu a ventricles ho

Ha e mong lateral ventricle (kapa ka bobeli) hlahisa mokelikeli ho feta ka e monyang e develops boemong pathological ka hydrocephalus. Moqolo oa ka hare ea ventricles butle-butle eketseha, compressing boko dinama tse nyenyane tse. Ka linako tse ling sena se isang ischemia etsolloa le necrosis.
