Cov cov neurons uas ua rau tus txha caj qaum ua tsis kheev kho lawv tus kheej. Neurons hauv nruab nrab lub paj hlwb-lub paj hlwb thiab tus txha caj qaum-thiab lub paj hlwb sab hauv yog zoo ib yam tshwj tsis yog lawv muaj peev xwm rov tsim dua tshiab. “Cov raug mob neuron yuav tsum tsis ua haujlwm li ib neuron thiab tsom mus rau kho nws tus kheej…”
Ntawm no, puas tuaj yeem puas neurons rov tsim dua?
Tsis ntev los no, biologists tau tshawb pom qhov ntawd paj hlwb tej zaum tuaj yeem tsim dua tshiab . Lawv tsuas tsis ua ua nws ntau heev lossis nrawm heev. Cov tawg paj hlwb tau 'tsis rov tsim dua lawv cov neurons kho lawv tus kheej. Tsis muaj cov no cov neurons , nws ua nyuaj los yog tsis yooj yim sua kom txav caj npab lossis txhais ceg lossis ua pa.
Ib yam li ntawd, cov neurons puas tuaj yeem rov qab los? Tus sau txoj kev tshawb fawb laus Gong Chen, uas yog xibfwb qhia txog biology ntawm Penn State, piav qhia qhov ntawd neurons ua tsis rov tsim dua tshiab thaum cov ntaub so ntswg puas. "Hauv qhov sib piv," nws hais ntxiv, "cov hlwb glial, uas sib sau ua ke ntawm cov ntaub so ntswg puas hlwb, ua tau loj hlob tom qab raug mob lub hlwb."
Ib yam li ntawd, nws raug nug, yuav ua li cas thaum neurons puas lawm?
Feem ntau cov neurons hauv nruab nrab lub paj hlwb tsis tuaj yeem kho lossis rov ua lawv tus kheej, tsis zoo li lwm cov cell hauv lub cev. Yog li, yog tias qee tus tuag los ntawm kev mob lossis puas , lub paj hlwb tuaj yeem poob qee yam ntawm nws lub peev xwm. Yog cov neurons tuag los ntawm kev mob los yog puas , lub paj hlwb tuaj yeem poob qee yam ntawm nws lub peev xwm.
Lub cev muaj zog neurons puas tuaj yeem kho tau?
Tsav tsheb neurons , uas muaj cov txheej txheem uas nyob hauv CNS thiab PNS, ua regenerate, txawm li cas los xij. Thaum tsis muaj kev cuam tshuam, lub cev muaj zog neurons yog ib tus ntawm CNS nkaus xwb cov neurons rov tsim dua tom qab axotomy.

Feem ntau ntawm koj cov neurons tsis tuaj yeem hloov pauv. Lwm qhov ntawm koj lub cev - xws li tawv nqaij thiab pob txha - tuaj yeem hloov pauv los ntawm lub cev loj hlob cov cell tshiab, tab sis thaum koj ua rau koj lub paj hlwb raug mob, koj tsis tuaj yeem cia li loj hlob tshiab xwb; Hloov chaw, cov cell uas twb muaj lawm yuav tsum kho lawv tus kheej
Puas tuaj yeem hloov neurons yog tias puas lawm?
Feem ntau ntawm koj cov neurons tsis tuaj yeem hloov tau. Lwm qhov ntawm koj lub cev - xws li daim tawv nqaij thiab pob txha - tuaj yeem hloov tau los ntawm lub cev loj hlob tshiab, tab sis thaum koj ua rau koj cov neurons raug mob, koj tsis tuaj yeem loj hlob tshiab; xwb, cov hlwb uas twb muaj lawm yuav tsum kho lawv tus kheej
Lub siab puas tuaj yeem kho tau los ntawm kev puas tsuaj acetaminophen?
Piv txwv li, kev siv tshuaj acetaminophen ntau dhau (Tylenol) tuaj yeem rhuav tshem ib nrab ntawm tus neeg lub siab lub hlwb hauv tsawg dua ib lub lim tiam. Kev txwv tsis pub muaj teeb meem, daim siab tuaj yeem kho nws tus kheej tag nrho thiab, hauv ib hlis, tus neeg mob yuav tsis pom qhov tshwm sim ntawm kev puas tsuaj

Txawm li cas los xij, yog tias APRN lossis PA tau nyob hauv daim ntawv pom zoo tso cai nrog kws saib xyuas kws kho mob tsawg kawg tsib ntawm xya xyoo dhau los, cov rooj sib tham tim ntsej tim muag yuav tsum tshwm sim tsawg kawg ib hlis txog rau thawj hnub ntawm hnub uas tau pom zoo kos npe
Dab tsi yog qee txoj hauv kev uas tus kws pab kho hniav tuaj yeem pab ua kom lub qhov ncauj qhuav li sai tau thaum cov txheej txheem kho hniav?
Cov txheej txheem ib txwm uas siv cov txheej txheem tswj hwm kev kho hniav suav nrog kev tu hniav, sau ua ke, sib sau ua ke thiab cov hauv paus hniav. Cov txheej txheem tswj kev ya raws sib txawv suav nrog cov txheej txheem tshem tawm qhov ncauj, yaug qhov ncauj kab noj hniav, thiab cais cov hniav
