aka spinotectal ib ntsuj av, lub spinomesencephalic kab mob yog ib feem ntawm lub anterolateral system; Nws xaus rau hauv periaqeductal grey ntawm midbrain. Lub periaqueductal grey yog xav tias yog ib qho chaw tseem ceeb rau inhibiting lossis tswj qhov mob thiab yog li cov kab mob spinomesencephalic pab txhawb rau lub luag haujlwm ntawd.
Spinotectal tract yog dab tsi?
: ib qho kev nce ntawm cov hlab ntsha hauv txhua sab ntawm funiculus ntawm cov teeb meem dawb ntawm tus txha caj qaum uas hla mus rau sab saud thiab xaus rau hauv cov kab mob siab tshaj ntawm sab nraud.
Dab tsi yog ib qho kev nce qib?
Ascending tracts yog sensory pathways that start at the spinal cord and stretch up to the cerebral cortex. Muaj peb hom ascending tracts, dorsal kem-medial lemniscus system, spinothalamic (los yog anterolateral) system, thiab spinocerebellar system.
qhov twg spinomesencephalic tract hla?
Feem ntau cov axons tsim cov kab mob spinomesencephalic hla nruab nrabthiab nce mus rau hauv lub ventrolateral funiculus ua ke nrog cov spinothalamic thiab spinoreticular tracts, tab sis axons ntawm lamina 1 spinomesencephalic kab mob neurons nce ob sab hauv. dorsolateral funiculus (Hylden li al., 1986).
tectospinal kab mob tuaj qhov twg?
Lub hauv paus chiv keeb ntawm Tectospinal ib sab yog nyob rau hauv lub superior colliculus ntawm lub midbrain. Raws li cheeb tsam no tau txais cov ntaub ntawv hais txog kev pom kev pom,Cov kab ke no feem ntau yog lub luag haujlwm rau kev kho kom haum xeeb cov lus teb rau qhov pom kev stimuli. Cov kab mob tectospinal muaj npe tom qab lub tectum, lub ntsiab lus ru tsev.
