Striatum kanye nokwenza imisebenzi yayo

Ubuchopho bomuntu - esiyinkimbinkimbi kakhulu e ekwakhekeni nasekumeni komzimba wabo, esakhiwa iqoqo ezinzwa kanye nomgudu walo. Ukuze omunye izingxenye zesakhiwo zobuchopho zihlanganisa striatum.

definition

umzimba Striate zobuchopho yilona hlaka yokwakheka we telencephalon, okuyinto siphathelene basal nuclei ama- ubuchopho bomuntu.

Igama umzimba abizwa kanjalo ngoba ine uhlobo bands ezilandelanayo ndaba elimhlophe kanye grey izingxenye engaphelele kanye ovundlile zobuchopho.

Izifundo zokuqala wabonisa ukuthi umsebenzi isiqongo striatal kuza ngesikhathi lapho umuntu ifinyelele eminyakeni engu-15 ubudala. Kodwa izifundo zamuva ezibonisa ukuthi umsebenzi wangempela umzimba uqala eduze engu-25, futhi hyperactivity zaba iminyaka engu-30.

Ngaphezu kwalokho, wachitha cwaningo ezithakazelisa kakhulu, abacwaningi batholé ukuthi ubuchopho aphendvule lapho inkokhelo azihlanganisiwe abantu umzamo zifakwe emsebenzini. Ngokwesibonelo, uma umsebenzi uyaqaphela ukuthi uzakwabo uthola esengeziwe esilinganayo umsebenzi, kushukunyiswe ukukhubazeka eside encishisiwe. Ngakolunye uhlangothi, isifiso umsebenzi kwandisa umsebenzi revaluation.

isakhiwo

Striatum liqukethe:

• Caudate-nucleus.
• nucleus we-lenticular wangakwesokunxele.
• Ezicijile.

Uma sicabangela umzimba ngesibonakhulu, liphethe izinzwa ezinkulu ngemisila eside kuyoshaya nangale kwemingcele striopallidarnoy uhlelo.

Izingxenye zomzimba we caudate - inhloko, umzimba kanye nomsila. Inhloko yakha odongeni uhlangothi uphondo anterior ka -ventricle lateral; umzimba core edonswa kanye ingxenye eyinhloko ventricle; umsila usodongeni phezulu aphansi izimpondo ventricle luphele lateral geniculate umzimba.

Kususwa udonga lwangemuva nengaphakathi ikhanda itholakala emngceleni ne thalamus, lubahlukanise band elimhlophe okuqinile.

nucleus we-lenticular wangakwesokunxele, njengoba leli gama lisikisela, ezakheke okusikhumbuza udali.

Itholakala ku ohlangothini-nucleus caudate kanye thalamus. Uma thina usike nengaphakathi ngesigamu, it has a ukuma nhlonhlo, phezulu okuyinto yaphenduka phakathi, kanti phansi - ohlangothini.

Isendlalelo elincane ndaba ezimhlophe sehlukaniswe tincenye eziningana core:

1. Igobolondo.
2. Lateral Globus pallidus.
3. Medial Globus pallidus.

Pallidus - eziwuhlobo imfundo lasendulo (umzimba ubudala) ukuthi ihlukile kwezinye izingxenye striatum kokubili macroscopic futhi histological kwengqondo.

Uthango itholakala ngaphandle kwe-nucleus lens emise. Ngaphandle, kuhle, kuze amamilimitha angu ezimbili, ipuleti grey ndaba. Phakathi ipuleti flat, futhi iqhubu encane grey ndaba onqenqemeni ohlangothini.

imisebenzi eyisisekelo

Striatum zobuchopho umzimba ubhekwa omunye izikhungo ezinkulu subcortical zokulawula kanye yekuchumanisa kohlelo ngamandla.

Through ucwaningo wafakazela ukuthi umzimba yakhiwa vegetative wokuxhumanisa izikhungo esilawula ukushisa isizukulwane, ukushisa ukukhululwa, umzimba kanye yokusabela izitsha.

Imisebenzi esemqoka umsebenzi striatum zihlanganisa:

• Regulation of kwemisipha ithoni.
• A ukwehla imisipha ithoni.
• Angenele ukulawulwa izitho zangaphakathi.
• Ukuhlanganyela izimpendulo kokuziphatha.
• Ukuhlanganyela kumiswa ikhaliphe moya.

Ukulimala striatum kanye nemiphumela

Lapho umzimba ezimthende uyeke ukusebenza, ukwephula ezilandelayo ebonwe abantu:

• Athetosis. Kuyinsakavukela kushintshana esitho ukunyakaza.
• Chorea. ukunyakaza engalungile ezenzeka ngaphandle ukulandelana noma oda sokudla umzimba wonke ezicutshini.
• Okhulisa ikhaliphe unconditioned (ukuzivikela njll Indlela).
• Hyperkinesia. isithuthukisi Obalulekile ukunyakaza asizayo lapho ahambe ezinyakazayo ngamunye eyinhloko.
• Hypotonia. Osabekayo imisipha ithoni, wehlise ke.
• Ukuvela Tourette Syndrome.
• Ukubukeka Parkinson yokufa izinzwa emzimbeni, ngenxa yalokho hhayi kukhiqizwa domafin, okuyinto unomthwalo isimiso sokutshuza zomzimba womuntu.
• Ukubukeka Huntington.

Ngaphandle umonakalo striatum futhi caudal nucleus ngokukhethekile:

• Ngokugcwele noma ingxenye ekuvimbeleni bezibona ubuhlungu, ezibukwayo, sokuzwa, nezinye izinhlobo ingqondo.
• Yehlisa noma kwandisa amathe.
• Ebambezela orientation emkhathini.
• Kwephula inkumbulo.
• It kubambezela ukukhula.
• Lokho kwenza ukunyamalala ikhaliphe ekhondishina esikhathini eside. Ukuziphatha kwabantu kungenza kube inert futhi amile.
