Ventricle Lateral: anatomy, umsebenzi

ventricle Lateral, kanye nezinye izimbotshana ubuchopho kuyingxenye uhlelo jikelele lapho yotshwala sisakazwe. Bona ukuxhumana ezikhaleni subarachnoid ka emgogodleni. Ebusweni engaphakathi ingaphakathi uphahlwe ependyma. Umsebenzi wawo iwukuhlale uhla kahle ingcindezi ngaphakathi nangaphandle kwe-asebuchosheni nomgogodla.

Izinhlobo ventricles ingqondo

ventricle Lateral (es) - umgodi elincane ubuchopho ezinkulu ezikhiqiza ethile uketshezi lomgogodla. Basuke kubhekwe kwekulu kohlelo ventricular. Lokhu kumiswa pair, futhi kukhona sendawo ethile ngaye.

I kwesokunxele ventricle lateral, ngokwemfundiso yesiko, ibizwa ngokuthi kuqala. Ilungelo - yesibili. Ziyakwazi ziyalingana nomunye futhi eduze izakhiwo yokwakheka, futhi ahlelwe ngezansi emaceleni epiphysis of umugca losemkhatsini esifubeni. ventricle ngamunye angawodwa nophondo umzimba phambi, nibulale ezingasemuva, ngezansi. Monroe ventricles lateral nge izimbobo exhunywe kwi-ventricle lwesithathu.

I-ventricle wesithathu itholakala phakathi izindawo obhekene umbono. It has simise indandatho nodonga lwawo ngubumpunga ndaba equkethe ganglia autonomic. Ngaphezu ventricles lateral, le ingaphakathi ixhunywe intambo namanzi.

I-ventricle wesine itholakala phakathi cerebellum aphansi. Ngesimo kufana mbhoshongo futhi kufanele ngokunembe kakhudlwana ukubizwa ngokuthi fossa rhomboid. Ngaphezu CSF ezansi kulo mgodi itholakala iningi nuclei we izinzwa emgogodleni.

plexus semithambo

ventricle Lateral (es) is kancane kuphela ebandakanyeke umqondo ezifana plexus semithambo. Eziningi zalezi izakhiwo asezindaweni ophahleni ventricles sesithathu nesesine. ' Bazi ukuthi banesibophezelo iningi ukukhiqizwa cerebrospinal fluid. Ngaphandle kwabo, lo msebenzi wenziwa ngqo izicubu kwemizwa, kanye ependyma ukuthi ihlanganisa ingaphakathi ventricles zobuchopho.

Morphologically, plexus semithambo kukhona amaqhubu pial alayishwe ventricles. Ngaphandle salezi ziboya embozwe cubic eziqondile choroid epithelium.

Ependimotsity

I ventricles lateral zobuchopho uphahlwe Indwangu ekhethekile ngaphakathi, okungase ukukhiqiza kokubili CSF futhi ukukuqonda. Lokhu kusiza ukugcina imali kahle uketshezi kule komgodi, futhi kwaphakanyiswa ingcindezi intracranial.

amaseli EPITHELIAL babe organelles amaningi ane-nucleus ezinkulu. Ebusweni elingaphandle yalo embozwe inqwaba microvilli, zisiza ukuthuthukisa uketshezi lomgogodla, kanye ukumuncwa yayo. ependyma Ngaphandle elise Kolmer emangqamuzaneni okuthiwa ama-ezibhekwa ngohlobo olukhethekile macrophage ukuthi ziyakwazi ezihambayo ngomzimba.

Ngokusebenzisa izikhala ezincane amaningi ulwelwesi engaphansi phakathi komgodi we epindemotsitov ventricles exuded plasma yegazi. Ukuze yengezwe amaprotheni ezivezwa epithelium ngokwayo izimbotshana sangaphakathi amangqamuzana obuchopho, futhi ngakho-ke kuvela oludakayo.

gazi ebuchosheni

ulwelwesi zayo zangaphakathi lomzimba akha uphondo ventricles lateral noma gazi ebuchosheni gematolikvorny. Kuyinto iqoqo izindwangu, wahlela ngeluhlelo lolutsite:

- cytoplasm ka capillary endothelium;

- zezinzwa izicubu equkethe ama-macrophage;

- endothelial engaphansi ulwelwesi;

- amaseli ependymal;

- engaphansi ulwelwesi ependyma.

Lokhu eyinkimbinkimbi kuyadingeka ukuze kuvinjelwe ku cerebrospinal fluid imikhiqizo umzimba, imithi nezinye ezinobuthi.

uketshezi lomgogodla

Kuyinsakavukela we ventricles lateral - amalitha ukukhiqizwa phansi kotshwala ngelanga, kodwa namashumi amane eyodwa kuphela futhi namamililitha kulesi samba ngokuqhubekayo lalikhona isikhala subarachnoid. Naphezu kweqiniso lokuthi isisekelo sokuthethelelwa cerebrospinal fluid kuyinto plasma, banayo kokungafani okukhulu kwenani electrolyte kanye amaprotheni. Eyokuqala - siphezulu, kanti eyesibili - ngezansi. Ngaphezu kwalokho, e yotshwala evamile ekhona ingane lemali lymphocyte. Reabsorption ka cerebrospinal fluid kwenzeka endaweni ye Isingeniso plexus semithambo.

Ukunikeza i-CSF imisebenzi elandelayo:

- ngokukhishwa kobuthi egazini (umzimba umkhiqizo ezokuthutha);

- ukumiswa (ngesikhathi ukuhamba, uwela, badedelane abukhali);

- kumiswa igobolondo emhlabeni izakhi hydrostatic isimiso sezinzwa;

- nokugcina Ukwakheka njalo uketshezi in isimiso sezinzwa esiyinhloko;

- ezokuthutha (ezokuthutha hormone nemithi ethile).

yezifo ventricles

Lapho omunye ventricle lateral (noma kokubili) ukukhiqiza uketshezi ezingaphezu kuka ukudla kwezimila sibangelwa isimo sokugembula njengoba iphimbo. Umqulu sangaphakathi ventricles ukwanda kancane kancane, ukugxisha nezicubu ingqondo. Kwesinye isikhathi lokhu kuholela ischemia awushintsheki futhi necrosis.

Kwezinhliziyo zezinsana nezezingane ezincane izimpawu zalesi sifo yilabo ubukhulu ongalingani Nogebhezi lwawo ziqhathaniswa ebusweni, fontanelle bulging, causeless ukukhathazeka ingane kuphenduke nokunganaki. Kubantu abadala, lokhu kukhona izikhalazo ikhanda, ubuhlungu emehlweni, isicanucanu nokuhlanza.

Ukuze uphethwe besebenzisa amasu neuroimaging: resonance kazibuthe noma ngekhompyutha yokwelapha tomography. Ukusheshe kutholakale kanye nokwelashwa yalesi sifo kuvimbela nabaningi yezinkinga futhi alondoloze kungenzeka ukuphila okuvamile.
