Lub cev muaj zog neurons nqa cov cim qhia los ntawm lub hauv paus paj hlwb mus rau sab nraud ntawm koj lub cev ua qhov tsis sib xws ntawm kev nkag siab neurons . Rau piv txwv , yog tias koj tsav tsheb, lub lub cev muaj zog neurons yuav muab cov lus los ntawm koj lub hauv paus paj hlwb rau koj txhais tes qhia koj kom tig tus yuam sij.
Raws li, dab tsi yog lub cev muaj zog neurons?
A lub cev neuron (lossis motoneuron) yog a neuron nws lub cev ntawm tes yog nyob rau hauv lub cev muaj zog cortex, lub paj hlwb lossis tus txha caj qaum, thiab nws txoj haujlwm axon (fiber) mus rau tus txha caj qaum lossis sab nraud ntawm tus txha caj qaum kom ncaj qha lossis tsis ncaj qha tswj lub cev ua haujlwm, feem ntau yog cov leeg thiab qog.
Ib qho ntxiv, dab tsi yog lub cev qis dua neurons? Tsawg lub cev muaj zog neurons (LMNs) yog lub cev muaj zog neurons nyob rau hauv ob qho tib si sab xub pwg grey, anterior paj keeb kwm (txha nraub qaum qis lub cev muaj zog neurons ) lossis cov hlab ntsha cranial ntawm lub paj hlwb thiab lub paj hlwb nrog lub cev muaj zog muaj nuj nqi (cranial paj qis lub cev muaj zog neurons ).
Ua li no, yuav ua li cas lub cev muaj zog neurons ua haujlwm?
Kev xav neurons nqa cov cim qhia los ntawm sab nraud ntawm koj lub cev (ib puag ncig) mus rau hauv lub hauv paus paj hlwb. Lub cev muaj zog neurons (motoneurons) nqa cov cim qhia los ntawm lub hauv paus paj hlwb mus rau sab nrauv (nqaij, tawv nqaij, qog) ntawm koj lub cev. Interneurons txuas ntau yam neurons nyob rau hauv lub hlwb thiab tus txha caj qaum.
Puas yog lub cev muaj zog neurons hauv lub hlwb?
Tsav tsheb neurons yog ib hom tshwj xeeb ntawm lub hlwb cell npe neurons nyob rau hauv tus txha caj qaum thiab lub lub hlwb . Lub sab sauv lub cev muaj zog neurons keeb kwm nyob rau hauv lub hlwb thiab taug kev nqes los txuas nrog qis dua lub cev muaj zog neurons.
