Ib qho txiaj ntsig tseem ceeb ntawm cov kev sim anatomical zuj zus no yog qhov ua qauv qhia ntawm cov kab tom qab. Xyoo 1826, tus kws kho mob German Karl Friedrich Burdach (1776–1847) tau piav qhia, los ntawm kev tshawb fawb macroscopic, lub fasciculus cuneatus, hu ua kab mob ntawm Bur-dach [5].

fasciculus cuneatus yog dab tsi?

Lub cuneate fasciculus, tseem hu ua fasciculus cuneatus (plural: fasciculi cuneati) lossis kem ntawm Burdach, sawv cev rau sab laug ntawm kab dorsal thiab nqa cov tswv yim los ntawm nruab nrab thiab suav nrog C1 thiab T61.

fasciculus gracilis nyob qhov twg?

Fibers nyob rau hauv gracile fasciculus originate los ntawm sacral, lumbar, thiab qis thoracic (hauv qab T6) qib; cov nyob rau hauv cuneate fasciculus originatelos ntawm sab sauv qaum (saum toj no T6) thiab cervical theem.

fasciculus gracilis yog dab tsi?

Fasciculus gracilis nqa cov ntaub ntawv nkag siab cuam tshuam nrog DCML txoj hauv kev los ntawm qis qis thiab txiav tawm thiab cov synapses ntawmnucleus gracilis hauv caudal medulla. Nws nyob nruab nrab txheeb ze rau fasciculus cuneatus thiab taug kev tag nrho raws tus txha caj qaum.

Ob thaj chaw twg txuas nrog fasciculus gracilis?

Kab dorsal tau muab cais ua ob ntu, lub fasciculus gracilis uas muaj axons los ntawm ob txhais ceg thiab qis lub cev, thiab fasciculuscuneatus uas muaj axons ntawm lub cev thiab caj npab.
