Kwakwalwa tsarin: da cerebellum, aiki

Tiyata da muka sani cewa kwakwalwa kunshi irin wannan sashen a matsayin oblong, matsakaici, tsaka-tsaki, da kuma raya karshen kwakwalwa. Bi da bi, da na baya da aka subdivided cikin da pons da cerebellum, tsarin da kuma ayyuka na wanda mu tattauna a wannan labarin.

Ya kamata a lura da cewa a cikin cerebellum ne ware biyu hemispheres, tsaka-tsaki rabu da wani da ake kira tsutsa saman rabu layi daya GROOVES tsakanin waxanda suke gyrus, dukan surface ne da ɗari takwas da hamsin square santimita. convolutions kungiyoyin samar da lobe da cerebellum, da furrows na da daskararrun kuma tafi daga tsutsa da yammancin duniya.

Kowane gyrus wakiltar wani bakin ciki Layer na fari al'amari mai rufi m (haushi) a cikin daya millimeter lokacin farin ciki. A cerebellum, wanda ake da alaka da aikin da tsarin, yana da ƙananan kafar (wajen samun da medulla oblongata), matsakaici (aika zuwa gada) da kuma na sama (aika zuwa quadrigemina). Wannan abu ne da alaka da duk sauran sassan na tsakiya m tsarin da yawa tafarkin da cewa kawo hasken dake fitowa daga tsokoki, da jijiyoyin, cerebral bawo da kuma tendons, da cerebellum kuma aika hasken dake fitowa ta hanyar wadannan tashoshi a sauran sassan na majalisar dokokin kasar. Saboda haka, wannan bangare na kwakwalwa da hannu a cikin tsari na mota aiki, yin motsi m, santsi da kuma proportionate.

Muhimmanci, a matsayin jiki, wanda aka kunshe a cikin motsi kula da tsarin, da cerebellum aikin da wadannan ayyuka:

1) da tsari na tsoka sautin, da kuma jiki hali.

2) Coordination of sauri ƙungiyoyi.

3) Coordination of m ƙungiyoyi.

Duk wadannan ayyuka ana mafi kyau abar kulawa karkashin rarrabuwa na cerebellum sassan. Bari mu bincika a cikin daki-daki, abin da ayyuka suna yi da cerebellum, musamman kowane daga cikin sassan.

A tsutsa ake dangantawa da iko na jiki balance, sautin da hali. Shi ne a cikin wannan yankin na'am da bayanai a kan matsayi da kuma matsayi na locomotor na'ura, sa'an nan kuma, bayan ta sarrafa wasu dokokin da aka aika zuwa da vestibular na'ura. Ya kamata a lura da cewa kau da cerebellar vermis take kaiwa zuwa ƙãra extensor tonus ne ma ya lura da rashin daidaituwa, Matsayi cibiyar nauyi, akwai ataxia.

Middle ofishin ne ke da alhakin m motsi da kuma su gyara, kazalika da zabar mafi kyau hali na yin motsi. Kaye take kaiwa zuwa hypermetric, disequilibrium.

Cerebellar hemispheres ne alhakin da ya faru na sosai m shakka directed ƙungiyoyi, wanda bayyana da kansa na gudãna bayanai na laka. Wadannan gwagwarmayoyi za a iya gani a wasanni ko wasa a m kayan aiki. Raunuka na kwakwalwa yankunan sa reshe ataxia, tremor, promahivaniya, hypotonia da tsoka megalografiyu.

More kwanan nan, masana kimiyya ya nuna cewa cerebellum da sauran ayyuka yana da, misali, shi ne a wani mataki da alhakin da ayyuka na gabobin da kyallen takarda. Idan ka cire cerebellum, shi zai zama wani take hakkin da zuciya da jini, miciwa, gastrointestinal fili.

Saboda haka, a sake, mu lura da cewa cerebellum, wanda ƙayyade da aiki da kuma yanayin da cuta a lokacin da shi ne zagi da hannu a cikin tsari na kayan ciki. Kaye, yana kawo irin wannan babban bayyanar cututtuka kamar asthenia (tsoka rauni), astasia (girgiza yunkuri na tsokoki) da kuma atony (rage tsoka sautin). Shi ne kuma quite na kowa su tsayar da ci gaban dysmetria - asarar daidaici motsi, ataxia - Gait nakasawa, adiadohokineza - asarar ikon yi motsi jerin.

Saboda haka, cerebellum aikin wani yawan ayyuka da cewa tabbatar da al'ada aiki da kwayoyin. Bugu da kari ga daidaituwa na ƙungiyoyi, kuma shi shirya aiki na duk kayan ciki da tsarin.
