Striatum ndi ntchito zake

Ubongo wa munthu - kuipidwa kwambiri dongosolo thupi lawo, chomwe ya maselo mitsempha ndi njira zawo. Mmodzi wa mbali structural ubongo zikuphatikizapo striatum.

tanthauzo

Striate thupi la ubongo dongosolo anatomical wa telencephalon ndi, limene limafotokoza kuti woyambira mtima hemispheres ubongo wa munthu.

Dzina la thupi wotchedwa chifukwa ali mawonekedwe a magulu motsatizana woyera ndi imvi nkhani ya zigawo mazunzo ndi yopingasa ubongo.

The maphunziro oyambirira anasonyeza kuti pachimake striatal ntchito pakubwera nthawi imene munthu ayamba zaka 15. Koma kafukufuku wa posachedwapa akusonyeza kuti ntchito yeniyeni ya thupi limayamba pafupi zaka 25, ndipo ofuntha kudawerengedwa kwa zaka 30.

Komanso, amacheza kuphunzira chidwi kwambiri, ofufuza anapeza kuti ubongo amayankha pamene malipiro si ataphimbidwa ndi khama anthu kugwira ntchito. Mwachitsanzo, ngati wantchito atazindikira kuti mnzake wake afika zambiri yofanana ntchito, kulimbikitsa vuto yafupika. Komano, kufuna ntchito kumawonjezera revaluation ntchito.

kapangidwe

Striatum tichipeza:

• Caudate phata.
• Lenticular phata.
• Mipanda.

Ngati tikambirana thupi pansi simungathe kutiona, tichipeza manyuroni lalikulu ndi michira yaitali kupitirira malire a dongosolo striopallidarnoy.

Ziwalo za thupi la caudate - mutu, thupi ndi mchira. Mutu ndipamene mbali linga la nyanga zapambuyo wa ku ventricle lateral; thupi pakati ali anakoka pamodzi gawo chapakati ventricle ya; mchira khoma pamwamba m'munsi nyanga ventricle ndipo itha pa lateral geniculate thupi.

Kumbuyo mpanda wa pakati mutu ili m'malire ndi thalamus ndi, ukugawa iwo gulu woyera olimba.

Lenticular phata, monga dzina lake likunenera, mawonekedwe ake amatikumbutsa zophika ndi.

Iwo unali mbali ya caudate phata ndi thalamus. Ngati kudula pachimake mu theka, ali mphero mawonekedwe, pamwamba amene inasanduka pakati, ndi pansi - mmbali.

A wosanjikiza ka nkhani woyera lagawidwa zigawo zingapo pakati:

1. Chipolopolo.
2. Ofananira globus pallidus.
3. Medial globus pallidus.

Pallidus - mtundu wa maphunziro wakale (thupi lakale) chosiyana ndi mbali zina za striatum onse macroscopic ndi histological wa mumtima.

mpanda ili kunja kwa phata mandala woboola pakati. Kunja, ndi bwino, mpaka millimeters awiri, mbale wa nkhani imvi. Pakati lathyathyathya mbale, ndipo ali lofufuma kwambiri mbali imodzi yaing'ono ya nkhani imvi kumbali m'mphepete.

ntchito zofunika

Striatum ubongo thupi imodzi ya akuluakulu subcortical malo zolimbana ndi Kutsata a dongosolo zosagwiritsa.

Kudzera zatsopano anatsimikizira kuti thupi zizindikiro vegetative Kutsata malo kuti zonse m'badwo kutentha, kutentha kumasulidwa, ndi kupukusa chakudya ndipo anachita ziwiya.

Ntchito yaikulu ya ntchito striatum monga:

• Lamulo minofu kamvekedwe.
• A kuchepa minofu kamvekedwe.
• Nawo lamulo ziwalo mkati.
• Kuthandiza pa mayankho khalidwe.
• Kutengapo mbali mu mapangidwe bongo wabwino.

Kuwonongeka kwa striatum ndi zotsatirapo

Pamene thupi milozo imaleka kugwira ntchito, ndi kuyan'anila zotsatirazi anati anthu:

• Athetosis. Zofala alternating nthambi kayendedwe.
• Chorea. kayendedwe pachithunzichi kuti saonetsa ndondomeko kapena kuti yolanda thupi lonse musculature.
• Amveke unconditioned bongo (kumbuyo zimasonyeza etc.).
• Hyperkinesia. Chochititsa chidwi kuwongola kayendedwe wothandiza zomwe zimayendera zoyenda chachikulu.
• Hypotonia. Yochititsa mantha minofu kamvekedwe, kuchepa izo.
• Zikamera wa syndrome Tourette a.
• Maonekedwe a matenda Parkinson kunathandiza kuti imfa ya manyuroni mu thupi, chifukwa cha zimene si opangidwa domafin, amene ali ndi udindo kwa Kanyama ka thupi la munthu.
• Maonekedwe a matenda Huntington a.

Kuwonjezera kuwonongeka kwa striatum ndi phata caudal makamaka:

• Kwathunthu kapena pang'ono kuteteza amaonera ululu, zithunzi, Makutu, ndi zina kukondoweza.
• Kumachepetsa kapena kumawonjezera salivation.
• Kumalepheretsa lathu mu mlengalenga.
• Kumaphwanya kukumbukira.
• Ndi kubweza pansi kukula.
• Imathandiza kuti mofulumira ya bongo wabwino mpaka kalekale. khalidwe la munthu angakhale inert ndi patsogolo.
