Polosatoe telo (lat. corpus striatum) -- anatomicheskaia struktura konechnogo mozga, otnosiashchaiasia k bazal'nym iadram polusharii golovnogo mozga[1]. Na gorizontal'nykh i frontal'nykh secheniiakh mozga polosatoe telo imeet vid chereduiushchikhsia polos serogo veshchestva i belogo veshchestva. V sostav polosatogo tela vkhodiat khvostatoe iadro i chechevitseobraznoe iadro, otdelionnye kapsulami[2][3].
Gistologicheskoe stroenie
[pravit' | pravit' kod]Mikroskopicheski sostoit iz krupnykh neironov s dlinnymi otrostkami, kotorye vykhodiat za predely striopallidarnoi sistemy.
Funktsii
[pravit' | pravit' kod]Polosatoe telo reguliruet myshechnyi tonus, umen'shaia ego; uchastvuet v reguliatsii raboty vnutrennikh organov; v osushchestvlenii razlichnykh povedencheskikh reaktsii (pishchedobyvaiushchee povedenie); uchastvuet v formirovanii uslovnykh refleksov. Pri razrushenii polosatogo tela proiskhodit:
- gipertonus skeletnykh myshts;
- narushenie slozhnykh dvigatel'nykh reaktsii i pishchedobyvaiushchego povedeniia;
- tormozitsia formirovanie uslovnykh refleksov.
Ventral'naia chast' polosatogo tela i prilezhashchee iadro reguliruiut pooshchrenie i podkreplenie v mozge. Dorsal'naia zhe chast' polosatogo tela bol'she vovlechena v regulirovanie motornykh funktsii. Dorsal'naia chast' takzhe sviazana s nalichiem impul'sivnosti povedeniia[4][5][6][7][8].
Sviazannye bolezni
[pravit' | pravit' kod]Porazhenie polosatogo tela mozhet vyrazhat'sia v sindrome Turetta. Neirony polosatogo tela pogibaiut pri bolezni Parkinsona. Pri povrezhdenii neironov v polosatom tele perestaiot vyrabatyvat'sia dofamin, otvechaiushchii za povedencheskie funktsii motivatsii i pooshchreniia. Takzhe striatum (kak i drugie struktury mozga v dal'neishem) porazhaetsia pri bolezni Khantingtona
