Ubongo wa munthu

Ubongo wa munthu pamodzi ndi amanena za dongosolo lawo chapakati mantha. Atabadwa ake kulemera alibe upambana magalamu 330 kapena 340. Pa siteji ya Ndisanaumbidwe ndi zaka zochepa ubwana, ubongo wa munthu kusiyana intensively. Kwa zaka 20 kukula udzatha. An waumuna ubongo kulemera anali 1375 ga, ndi mkazi - 1275 Zochepa thupi mu kugonana fairer chifukwa kukula chonse ang'onoang'ono. misa A amachepetsa msinkhu, osati ziwalo zonse, kuonda ndi ubongo.

Matenda a iye, ndipo opareshoni amaphunzira ubongo - mwambo wa dongosolo zotumphukira mantha ndi pakati.

Iwo ali mutu ubongo wa munthu M'mimbamo cranial. Amakhala wa hemispheres oziziritsa ndi cerebellum ndi mbiya.

Kutalikirana mu ubongo wa zigawo zisanu: a amalire ubongo, pakati, zapambuyo, wapakatikati ndi yaitali. Pitani asamathe umanena pa chingwe msana. Kupitiriza khosi gawo ake ndi medulla. mawonekedwe ake akufanana babu elongated. Ndi kumtunda kwa medulla oblongata akudutsa mu kumbuyo, zomwe zikuphatikizapo cerebellum ndi mlatho. chinsinsi chake imvi ndipamene zilumba payekha - cranial mitsempha mtima - zipilala osati olimba monga chingwe msana. Lilinso ndi mauna mapangidwe chifukwa ndondomeko, inakula maselo ubongo. Mlatho ali ngati wodzigudubuza anapeka ulusi mitsempha. Mbali kumbuyo kwa kufika nkhani imvi mu mawonekedwe a mtima wa misempha cranial. Ndi Mapeto itsekeke pang'ono ndipo itha pakati cerebellum, kumene kukhala pa pons ndi medulla oblongata, atseka iwo pafupifupi mwathunthu. Kuchokera pamwamba ali ndi imvi nkhaniyo grooves lagawidwa zigawo.

Midbrain kudutsa Korinto zogwiritsidwa mmbuyo. Pamafunikanso miyendo ndi matupi quadrigeminal. Izi mbale dzina la denga walandira kwa gulu m'magulu awiri phiri pamwamba, amagwirizana ndi masomphenya, ndi pansi awiri kugwirizana ndi kumva. Chigawo mtanda wa midbrain ndi m'munsi mwa miyendo ubongo tayala ndi denga. Pakati pa miyendo ndi denga lagona ngalande ubongo. tayala A lili reticular mapangidwe ndi iwiri ikuluikulu wofiira phata.

Mu corpus callosum ndi a midbrain, umene uli mbali ya mafyuzi ndi hemispheres ubongo. Iwo ali anayi phiri: zithunzi, zabugornom m'dera nadbugornuyu ndi podbugornuyu. M'mimbamo diencephalon - ndi ventricle lachitatu.

Anthu oziziritsa kotekisi zikuoneka ngati vuto imvi kuphimba Chigawo komanso kukhala ndi makulidwe a 5 mm. Kupanga mitsempha yake ulusi ndi maselo (manyuroni), zomwe kugona mu zigawo mu dongosolo linalake. Makungwa ndi losanganikirana. Lililonse gawo la matabwa ake ndi ulusi osiyana ndi maselo. Ichi ndi chifukwa ntchito kuti amachita. Ndipotu mbali ya ubongo payokha amalandira nyemba asafike padziko lonse la zimakhala ndi ziwalo. Mwachitsanzo, njira ya chizindikiro Makutu kutsirizitsa mu Lobe wosakhalitsa, zithunzi - ndi kotekisi occipital etc. amu nayenso kutumiza nyemba kwa malo ake ena tsinde ubongo ...

Komanso, ubongo, komanso dorsal, aphimbidwa ndi zipolopolo atatu: mtima (zofewa), arachnoid ndi olimba. The periosteum mafupa chigaza - ichi ndi chipolopolo zovuta. Padziko ubongo ndi wochepa thupi, osati munali Mitsempha arachnoid. A ubongo mwake, ziwiya ndi zizindikiro zofewa kwambiri, kulola kuti lembani mizere onse ndi ubongo kudula. Popanda sikutheka mapangidwe a plexus mtima wa ventricles lapansi.

Popeza chingwe msana ndi ubongo cholukanalukana, kulephera kwa mmodzi wa iwo kwenikweni kumabweretsa kuphwanya bongo, amene ali ndi udindo kwa ena. ubongo ndi anawonjezera kutopa, kutopa ntchito kungachititse kuti matenda aakulu a dongosolo chapakati mantha a umunthu.
