Cov nruab nrab cerebellar peduncles (brachium pontis) yog cov qauv ua ke (sab laug thiab sab xis) uas txuas rau lub paj hlwb rau cov pons thiab tau tsim los ntawm cov fibers centripetal nkaus xwb, piv txwv li cov khoom tuaj. Cov fibers tshwm sim los ntawm pontine nucleus mus rau qhov sib txawv hemisphere ntawm lub paj hlwb cortex.
Yog li ntawd, dab tsi yog qhov ua haujlwm ntawm lub paj hlwb peduncles?
Cerebellar peduncle yog txoj hlab ntshav uas tso cai sib txuas lus ntawm cerebellum thiab lwm qhov ntawm lub hauv paus paj hlwb. Peb khub ntawm cerebellar peduncles ua qhov kev sib txuas lus no. Cov qis dua peduncles nqa cov ntaub ntawv paub txog qhov tseeb ntawm txoj haujlwm ntawm lub cev xws li txhais ceg thiab pob qij txha.
Tsis tas li, qhov nruab nrab cerebellar peduncle nyob qhov twg? Cov nruab nrab cerebellar peduncles yog cov qauv ua ke uas txuas rau lub paj hlwb rau cov pons thiab tau tsim los ntawm cov fibers centripetal nkaus xwb, uas tshwm sim los ntawm pontine nucleus ntawm sab nraud thiab xaus rau hauv lub paj hlwb cortex; cov fibers tau teeb tsa hauv peb qhov fasciculi, zoo dua, qis dua, thiab tob.
Ua qhov no hauv kev txiav txim siab, peb lub cerebellar peduncles yog dab tsi?
Muaj peb ntawm txhua sab: qis dua peduncle ntawm cerebellar (#4025, #6172), nruab nrab peduncle ntawm cerebellar (brachium pontis) (#8361, #6553), thiab zoo dua peduncle ntawm cerebellar (brachium conjunctivum) (#6554). Qhov nruab nrab thiab qis dua peduncles ntawm cerebellar muaj feem ntau ntawm cov lub paj hlwb afferents.
Dab tsi yog qhov sib txawv ntawm qhov nruab nrab zoo thiab qis dua cerebellar peduncles thiab cerebral peduncles?
Superior cerebellar peduncle yog cov qauv ua khub ntawm cov teeb meem dawb uas txuas rau lub paj hlwb rau nruab nrab -lub paj hlwb. Peduncle cerebellar qis dua yog txoj hlua zoo li cov hlua uas nyob rau sab saud ntawm cheeb tsam tom qab ntawm medulla oblongata.

Dab tsi yog qhov nruab nrab nruab nrab txhim kho rau?
Thaum lub sijhawm embryonic kev txhim kho, lub nruab nrab lub paj hlwb (tseem hu ua mesencephalon) tshwm sim los ntawm ob lub vesicle ntawm cov hlab ntsha neural, thaum sab hauv ntawm lub raj no dhau los ua lub paj hlwb. Nws tsis faib mus rau lwm qhov chaw hauv hlwb
Qhov nruab nrab nyob nruab nrab txhais li cas?
Medial hais txog txhua yam mus rau nruab nrab ntawm lub cev. (Qhov tsis sib xws yog ib sab.) Qhov sib thooj hais txog lub ntsiab lus ze rau qhov taw tes siv. (Qhov sib txawv yog nyob deb.) Peripheral hais txog txhua yam uas nyob deb ntawm qhov chaw thiab paub qhov sab ntug ntawm yam
Qhov nruab nrab nruab nrab ntawm tus ncej puab ua dab tsi?
(Qhov nruab nrab nruab nrab yog nyob hauv nruab nrab txoj cai.) Qhov nruab nrab nruab nrab ntawm tus ncej puab yog ib qho ntawm fascial compartments ntawm tus ncej puab thiab muaj lub duav adductor nqaij thiab cov leeg gracilis. Lub paj hlwb obturator yog thawj lub paj hlwb muab cov khoom no. Obturator artery yog cov ntshav xa mus rau tus ncej puab nruab nrab
Dab tsi yog qhov nruab nrab nruab nrab ntawm patella?
