Ubongo dongosolo: ndi cerebellum, ntchito

Wa thunthu tikudziwa kuti ubongo tichipeza m'madipatimenti monga oblong, sing'anga, wapakatikati, ndi kumbuyo mapeto a ubongo. Nawonso hindbrain ndi lophatikizana ndi ubwamunalo linagawanika mu za pons ndi cerebellum, kapangidwe ndi ntchito umene ife m'nkhani ino.

Tikumbukenso kuti cerebellum n'kopanda hemispheres ziwiri, wapakatikati tasiyana otchedwa pamalo nyongolotsi anapambulwa grooves Kufanana amene ali gyrus, padziko lonse ndi mazana asanu ndi makumi asanu masentimita lalikulu. convolutions magulu kupanga Lobe wa cerebellum, ndi mizere olimba wake ndi kupita ku mbozi kuti Chigawo cha.

Aliyense gyrus akuimira wosanjikiza zonyalazo woyera nkhani TACHIMATA imvi (khungwa) mu millimeter munthu wakuda. The cerebellum, amene chokhudzana ndi ntchito ya kapangidwe ake, ali ndi mwendo m'munsi (malangizo kuti ndi medulla oblongata), sing'anga (anatumiza kwa mlatho) ndi chapamwamba (anatumiza kwa quadrigemina). Bwino chikugwirizana ndi madipatimenti ena onse a dongosolo chapakati mantha ndi njira zambiri zimene zichita zikhumbo kwa minofu, Mitsemphayi oziziritsa kotekisi ndi tendons, ndi cerebellum komanso akutumiza zikhumbo kupyolera mu njira izi m'madipatimenti ena a National Assembly. Choncho, gawo ili la ubongo nawo lamulo la zochitika za galimoto, kupanga kusuntha zolondola, yosalala ndi kuja.

Chofunika, monga thupi, amene m'gulu dongosolo zoyenda ulamuliro, ndi cerebellum amachita ntchito zotsatirazi:

1) lamulo minofu kamvekedwe, ndi kaimidwe thupi;

2) Mgwirizanowu kayendedwe mwamsanga.

3) Mgwirizanowu kayendedwe cholinga;

ntchito zonsezi ndi bwino mu gulu la Dipatimenti ya cerebellum. Tiyeni tione mwatsatanetsatane zimene zimagwira ntchito zimagwiridwa ndi cerebellum, makamaka aliyense m'madipatimenti ake.

nyongolotsi amagwirizana ndi ulamuliro wa thupi bwino, kamvekedwe ndi kaimidwe. Ndi m'dera lino amalandira mauthenga pa zokhudzana ndi udindo wa zida za locomotor, ndipo patatha ake processing malamulo ena zimatumizidwa zida za vestibular. Tikumbukenso kuti kuchotsa vermis cerebellar kumabweretsa kuchuluka extensor tonus ndi ananena vutoli, synergy, pakati yokoka, pali ataxia.

ofesi Middle ndi udindo kayendedwe mwadala ndi chilangizo awo, komanso kusankha kaimidwe bwino kuchita gululi. kugonjetsedwa kwake kumabweretsa hypermetric, disequilibrium.

hemispheres Cerebellar ali ndi udindo pakutchulidwa wa mofulumira kwambiri kayendedwe ndithudi analamulira, amene uka popanda kudziwa akuthamanga wa chingwe msana. magulu awa Tingaone mu masewera kapena kugwiritsa ntchito chida choimbira. Zotupa m'madera ubongo amachititsa nthambi ataxia, kugwedeza, promahivaniya, hypotonia ndi minofu megalografiyu.

Posachedwapa, asayansi anasonyeza kuti cerebellum ndi ntchito zina ali Mwachitsanzo, kuti ena digiri amachititsa magwiridwe a ziwalo ndipo zimakhala. Ngati inu kuchotsa cerebellum, zidzakhala kuphwanya ziwiya mtima ndi magazi, dongosolo kupuma thirakiti m'mimba.

Choncho, kachiwiri, tiona kuti cerebellum, zomwe kudziwa ntchito ndi chikhalidwe cha matenda pamene nkhanza nawo lamulo ziwalo mkati. kugonjetsedwa kwake amachititsa zizindikiro ngati waukulu monga asthenia (kufooka minofu), astasia (kugwedeza kayendedwe ka minofu) ndi atony (utachepa minofu kamvekedwe). Ndi zachilendo kusunga chitukuko cha dysmetria - imfa kuyenda mwatsatanetsatane, ataxia - gait mapindikidwe, adiadohokineza - Amalephera kuchita mbali kuyenda.

Choncho, cerebellum amachita angapo ntchito zimene kuonetsetsa uziyenda wabwinobwino wa chamoyo. Kuwonjezera pa mgwirizano kayendedwe, ndipo nthawi kugwira ntchito kwa ziwalo zonse za mkati ndi kachitidwe.
