Dorsal spinocerebellar txoj hlab ntaws nthuav qhia cov ntaub ntawv los ntawm cov tswv cuab hauv cov leeg pob txha thiab pob qij txha mus rau lub paj hlwb . Nws yog ib feem ntawm cov txheej txheem somatosensory thiab ua haujlwm sib luag nrog cov hlab ntsws spinocerebellar.
Tsis tas li ntawd, txoj haujlwm ntawm spinocerebellar yog dab tsi?
Cov spinocerebellar kab mob yog afferent neurons uas xa cov ntaub ntawv tsim tawm los ntawm tus txha caj qaum mus rau cerebellum. Cov no daim ntawv ua si qhov tseemceeb lub luag hauj lwm hauv cerebellar-cortical-spinal tawm tswv yim loops tsim nyog rau kev sib npaug thiab kev sib koom tes.
Tsis tas li, qhov spinocerebellar tracts nyob qhov twg? Kev kwv yees los ntawm Spinal Cord mus rau Cerebellum. Cov spinocerebellar kab mob yog nyob nyob rau ib puag ncig ntawm kev lom zem sab hauv thiab nqa cov ntaub ntawv tsim nyog thiab txiav tawm los ntawm Golgi cov leeg nruab nrog cev thiab cov leeg spindles mus rau cerebellum.
Xav txog qhov no, cov ntaub ntawv xov xwm dab tsi uas spinocerebellar txoj kab nqa?
Cov spinocerebellar tracts nqa proprioceptive cov ntaub ntawv mus rau lub cerebellum. (Tsuas yog ib qho txoj kab tau ntxaws ntxaws ntawm txhua sab, txawm hais tias txhua sab muaj ob qho tib si daim ntawv .) Hauv lub paj hlwb somatic (SNS), lub cev muaj zog loj neuron hauv CNS tswj hwm lub zog qis hauv lub paj hlwb hauv lub paj hlwb lossis tus txha caj qaum.
Puas yog spinocerebellar ib leeg nce lossis nqis?
Ascending daim ntawv Dorsal kem yog thaj chaw ntawm kev hnov kev co, kev xav, thiab kev ntxub ntxaug ob lub ntsiab lus. Spinocerebellar tracts (anterior thiab posterior divisions) ua tsis nco qab stimuli rau proprioception nyob rau hauv cov pob qij txha thiab cov leeg. Cuneocerebellar nqa cov ntaub ntawv zoo ib yam li spinocerebellar kab mob.
