Cov cerebral peduncles yog ob lub stalks uas txuas lub cerebrum mus rau lub hlwb. Lawv yog cov qauv nyob rau hauv pem hauv ntej ntawm lub midbrain uas tshwm sim los ntawm pem hauv ntej ntawm lub pons thiab muaj lub loj ascending (sensory) thiab nqis (motor) paj hlwb uas khiav mus thiab los ntawm lub cerebrum los ntawm lub pons.
Raws li, qhov nruab nrab cerebellar peduncle muaj dab tsi?
Cov nruab nrab cerebellar peduncles (Brachium pontis) yog cov qauv ua ke (sab laug thiab sab xis) uas txuas rau cerebellum mus rau pons thiab yog muaj pes tsawg leeg ntawm centripetal fibers, piv txwv li cov khoom nkag. Cov fibers tshwm sim los ntawm pontine nucleus mus rau qhov sib txawv hemisphere ntawm lub paj hlwb cortex.
Ib tus kuj tseem yuav nug tau, qhov sib txawv ntawm qhov nruab nrab zoo thiab qis dua cerebellar peduncles thiab cerebral peduncles yog dab tsi? Superior cerebellar peduncle yog ib tug khub qauv ntawm cov teeb meem dawb uas txuas cov cerebellum mus rau nruab nrab - hlwb. Peduncle cerebellar qis dua yog ib txoj hlua tuab zoo li txoj hlua uas nyob rau sab sauv ntawm lub koog tsev kawm ntawv tom qab ntawm medulla oblongata.
Kuj nug, dab tsi yog crus cerebri?
Lub paj hlwb crus ( crus cev ) yog ib feem ntawm lub paj hlwb peduncle uas muaj cov kab mob hauv lub cev, taug kev los ntawm lub paj hlwb mus rau lub pons thiab qaum. Plural uas yog cerebral crura . Nws ua rau feem ntau ntawm lub hauv paus pedunculi nyob rau hauv midbrain.
Puas yog cerebral peduncle grey lossis teeb meem dawb?
neuroanatomy lub sij hawm xoob siv rau ntau yam stalklike txuas cov qauv hauv lub lub hlwb , tsim los tsuas yog ntawm qhov teeb meem dawb (piv txwv li, cerebellar peduncle ) los yog dawb thiab grey teeb meem (piv txwv li, cerebral lub paj hlwb ).

Dab tsi yog posterior cerebral artery?
Anatomical terminology. Cov hlab ntshav posterior posterior cerebral artery (PCA) yog ib qho ntawm cov hlab ntsha uas muab cov ntshav oxygenated mus rau lub lobe occipital, ib feem ntawm sab nraum qab ntawm tib neeg lub hlwb
Dab tsi yog qhov zoo tshaj cerebellar peduncle?
Kev faib tawm qhia pom qhov ua kom pom ntawm cov cerebellum. (Superior peduncle daim ntawv lo nyob rau nruab nrab sab saud.) Hauv tib neeg lub hlwb, qhov zoo tshaj cerebellar peduncle (brachium conjunctivum) yog cov qauv ua khub ntawm cov teeb meem dawb uas txuas lub cerebellum mus rau nruab nrab lub paj hlwb
Dab tsi yog txoj haujlwm ntawm sab laug cerebral hemisphere?
Sab laug ntawm lub paj hlwb yog lub luag haujlwm tswj hwm sab xis ntawm lub cev. Nws tseem ua haujlwm uas yuav tsum ua nrog kev xav, xws li hauv kev tshawb fawb thiab lej. Ntawm qhov tod tes, sab xis lub ntiaj teb ua haujlwm sab laug ntawm lub cev, thiab ua cov haujlwm uas tau ua nrog kev muaj tswv yim thiab txuj ci yeeb yam
Dab tsi yog qhov feem ntau occluded cerebral artery?
Yam Tseem Ceeb: Hnub nyoog laus; Kev nyuaj siab (mob siab); Txiv neej
Dab tsi tsis zoo ntawm cerebellar peduncle muaj?
Clinical neuroanatomy Lub cerebellar peduncles muaj qhov cuam tshuam thiab muaj txiaj ntsig zoo ntawm cerebellum. Cov cerebellar qis dua peduncle muaj plaub txoj kab sib txawv (posterior spinocerebellar, vestibulocerebellar, olivocerebellar thiab reticulocerebellar) thiab ib qho kev ua haujlwm zoo (cerebellovestibular tract)
