Ventricles oziziritsa

ventricles ya ubongo - ndi M'mimbamo ili mu zonse m'madipatimenti ake. Ali odzazidwa ndi madzimadzi (msana). Ventricles ubongo - anachokera ku thupi cavities sekondale kuwira. Pamwamba lamkati la zipupa ependyma. Kuonetsetsa zinayi zokha ventricle.

Woyamba ndi wachiwiri kumanzere-bwino ofananira, ndipo cavities ndi hemispheres. ventricles ubongo izi imakonzedwa pa za corpus callosum mu makulidwe a oziziritsa kanthu woyera. Mu mbali zomwe agulu lotsogolera anayi amalembedwa. The narrowest, chigawo chapakati lili Lobe parietal. Iwo encloses thalamus pamwamba ndi chimachititsa kuti nyanga kutsogolo anteriorly mu zapambuyo nyanga chagada downwards kwa m'munsi ventricle nyanga. Zapambuyo nyanga lili Lobe mazunzo, occipital nyanga ndi kumbuyo, pansi nyanga lagona Lobe mwakanthawi. The lateral symmetrical ventricles ubongo anasiyanitsidwa ndi mandala khoma kutsogolo. Amakhala ndi mbale ziwiri.

Lembani wina kutsogolo kwa ventricle lachitatu anachita ntchito dzenje interventricular. Pa medial mbali mtima plexus anapanga anakafika m'chigawo chapakati. Iwo aumbike mwa oziziritsa mtima Kakhungu gawo kuti mutuluka mu m'munsi nyanga ventricles symmetrical. plexus mtima wa ventricles lateral ndi wachitatu amafotokozedwa ntchito mabowo interventricular.

The ventricle chachitatu ndi M'mimbamo mu diencephalon. Iye ankayimiridwa ndi danga yopapatiza anatumbula ngati, ili mu ndege sagittal.

mbali makoma ake popangidwa ndi zigawo medial wa thalamus, m'munsi - ndi ubongo imene imalamulira kutentha. Front ventricle ndi njanjira pansipa ndi mbale woonda kudutsa upwardly m'madanga imatambasula. mpanda wake kumbuyo juts pa gawo lake m'munsi mwa malangizo caudal, kupanga nadshishkovidnoe recess. Pamwamba pa ventricle lachitatu m'mphepete mwa corpus callosum, ndi ubongo m'chipinda chotetezeka. mpandawo aumbike mtima plexus maziko. M'mimbamo amasuntha posteriorly mu ubongo madzi, umene ndi danga midbrain ndi zikugwirizana ndi ventricle wachitatu ndi wachinayi.

IV ventricle - ndi M'mimbamo wa medulla oblongata ndi mlatho (mu embryogenesis hindbrain). Rhomboid fossa ndi pansi pake. Pa ventricle yachinayi cerebellum. Denga ake ngati hema matabwa. Chutes (ubongo matanga) - mbale ubongo mankhwala. Mmodzi wa matanga (kumtunda) tensioned pakati pa miyendo cerebellar (kumtunda) ndipo imagwiritsidwa kumbuyo chapamwamba dera la denga. Kumbuyo gawo pansi aumbike mwa limbikitsa m'munsi. Iwo Ufumuyo miyendo m'munsi ndi lobule (zidutswa) wa cerebellum lapansi. United pamwamba kupalasa, chimene chinapanga makona protrude mu izo.

The otsetsereka m'munsi wa mkati m'munsi mwa chachinayi ventricle dongosolo pafupi mtima. The mtima anapanga m'badwo thicker wa madzimadzi cerebrospinal. M'mimbamo ndi msana njira malinga ndi fossa rhomboid m'chigawo cha ngodya zake m'munsi.

Kumbuyo m'munsi gawo la denga ali mipata atatu. Middle, ndi dziko lalikulu, yomwe ili m'chigawo chapakati cha otsetsereka m'munsi. M'chigawo cha ngodya lateral wa rhomboid mu fossa ndi mbali mabowo. Kudzera mipata izi ikuchitika mgwirizano pakati M'mimbamo ndi yamitsempha yamagazi ndi danga subarachnoid.

Pakuti munthu wina anomalies ndi, amakwiya chitukuko cha nambala ya matenda okhudzana asymmetry wa ventricles ubongo. Ndi matenda pafupipafupi ndi kuchuluka intracranial kuthamanga. Kudziwika anayerekezera zimene angathe amasonyeza kukhalapo kwa chotupa mu ubongo kapena hydrocephalus mkati (hypertensive-hydrocephalic syndrome). Ndi lingaliro ili amatanthauza zovuta zizindikiro zimene zimachititsa mapindikidwe (mkati ndi kunja) ndi precipitating kuwonjezeka ubongo ventricles.
