… lub caudal ib feem ntawm lub lub cev liab , ib pawg cell encapsulated nyob rau hauv lub midbrain tegmentum. Fibers ntawm txoj kab no decussate nyob rau theem nruab nrab ntawm lub paj hlwb, nqis los rau sab nraub qaum funiculus ntawm tus txha nqaj qaum (sib tshooj qhov chaw ntawm lub corticospinal txoj hlab pas), nkag mus rau qhov teeb meem txha nraub qaum, thiab txiav tawm ntawm interneurons hauv lamina …
Ib yam li ntawd, qhov twg yog Rubrospinal tract Decussate?
Cov rubrospinal kab mob siv keeb kwm nyob rau hauv lub liab nucleus. Cov txoj kab fibers sib tham thiab nqis los hauv qhov kev lom zem ntawm tus txha nqaj qaum, nruab nrab mus rau thiab ib nrab cuam tshuam nrog, cov fibers ntawm ob sab corticospinal daim ntawv.

Tus qauv yog nyob nyob rau hauv lub tegmentum ntawm lub midbrain nyob ib sab ntawm lub substantia nigra thiab suav nrog caudal magnocellular thiab rostral parvocellular Cheebtsam. Cov lub cev liab thiab substantia nigra yog subcortical chaw ntawm lub cev muaj zog extrapyramidal.
Rubrospinal tract hla qhov twg?
Nyob rau hauv lub midbrain, nws originates nyob rau hauv lub magnocellular liab nucleus, ntoo khaub lig mus rau lwm sab ntawm lub midbrain, thiab nqis los nyob rau hauv lub lateral ib feem ntawm lub brainstem tegmentum. Nyob hauv tus txha nqaj qaum, nws taug kev los ntawm qhov kev lom zem ntawm tus txha nqaj qaum, ua ke nyob ib sab mus rau sab laug corticospinal txoj kab.
