Qhov txhab mus rau lub paj hlwb tuaj yeem ua rau dyssynergia, dysmetria, dysdiadochokinesia, dysarthria thiab ataxia ntawm stance thiab taug kev. Kev tsis txaus yog pom nrog kev txav ntawm tib sab ntawm lub cev raws li cov mob ( ipsilateral ).
Ua kom pom qhov no, yog vim li cas cerebellar lesions ipsilateral?
A mob hauv ib lub paj hlwb hemisphere yuav ua rau lub cev muaj zog tsis txaus ntawm lub ipsilateral sab ntawm lub cev. Qhov no yog vim "ob npaug hla" (piv txwv li, cov khoom siv fiber ntau hla kom mus txog lub paj hlwb , thiab lub paj hlwb cov fibers tso tawm hla mus txog lawv lub hom phiaj).
Qhov thib ob, dab tsi ua rau muaj qhov txhab ntawm cerebellum? Cerebellar kev nyuaj siab muaj ntau heev ua , suav nrog kev tsis sib haum xeeb ntawm lub hauv paus, keeb kwm ntawm ataxia, thiab kis tau tus mob. Cov tsos mob sib txawv nrog cov ua tab sis feem ntau suav nrog ataxia (cov leeg tsis sib haum xeeb). (Saib Ntxiv Cov Txheej Txheem ntawm Kev Hloov thiab Cerebellar Teeb meem.)
Ib yam li ib tus tuaj yeem nug, puas yog cerebellum tswj ipsilateral lossis cuam tshuam?
Tsis zoo li cerebral cortex, tus lub paj hlwb tau txais cov tswv yim los ntawm, thiab tswj output rau, lub ipsilateral sab ntawm lub cev, thiab kev puas tsuaj rau lub lub paj hlwb yog li ntawd yuav ua rau deficits rau lub ipsilateral sab ntawm lub cev.
Vim li cas cov kab mob cerebellar ua rau hypotonia?
Hypotonia yog xav tias yuav cuam tshuam nrog kev cuam tshuam ntawm kev cuam tshuam los ntawm cov neeg txais tos thiab/lossis tsis muaj lub paj hlwb 's kev pab cuam efferent cuam tshuam rau lub fusimotor system, lub kaw lus uas innervates intrafusal nqaij fibers li tswj cov leeg spindle rhiab heev.

Kev mob nyob rau hauv ib qho cerebellar hemisphere yuav ua rau lub cev tsis muaj zog ntawm sab ipsilateral ntawm lub cev. Qhov no yog vim "ob npaug hla" (piv txwv li, cov khoom siv fiber ntau hla mus txog rau lub cerebellum, thiab cov cerebellar tso tawm cov fibers hla mus txog lawv lub hom phiaj)

Lub stretch thiab Golgi tendon reflexes ua haujlwm nyob rau hauv tandem los tswj cov leeg ntev thiab nro. Ob qho no yog piv txwv ntawm ipsilateral reflexes, txhais tau tias qhov kev xav rov tshwm sim ntawm tib sab ntawm lub cev raws li kev txhawb nqa
