S altatory conduction nyob rau hauv unmyelinated axons: pawg ntawm Na+ channels ntawm lipid rafts enables micro-s altatory conduction nyob rau hauv C-fibers. Lub peev xwm ua tau (AP), lub cim tseem ceeb ntawm lub paj hlwb, yog nqa los ntawm ob hom axons: unmyelinated thiab myelinated fibers.
Puas S altatory conduction tshwm sim hauv myelinated axons?
S altatory conduction tshwm sim tsuas yog ntawm myelinated axons.
hom kev coj ua dab tsi tshwm sim hauv Unmyelinated axons?
Cov ntsiab lus hauv cov txheej no (70) Hom kev coj ua dab tsi tshwm sim hauv cov axons uas tsis muaj menyuam yaus? rationale: Ib qho peev xwm ua tau yog ua tsis tu ncua raws ib qho kev tsis sib haum xeeb ntawm axon los ntawm nws thawj ntu mus rau axon terminals.
Dab tsi tshwm sim raws Unmyelinated axons?
Myelin Txhawb Kev Tshaj Tawm nrawm nrawm Nrog AxonsNyob rau hauv cov axons uas tsis muaj myelinated, qhov kev txiav txim muaj peev xwm taug kev tsis tu ncua raws axons. Piv txwv li, nyob rau hauv unmyelinated C fibers uas ua rau mob los yog kub (0.4-1.2 μm nyob rau hauv txoj kab uas hla), conduction tshaj tawm raws axon yog 0.5-2.0 m / s (ceev ceev li koj taug kev los yog jog).
S altatory conduction yog dab tsi Vim li cas nws tseem ceeb nws tshwm sim hauv myelinated los yog unmyelinated axons?
Cov teeb liab hluav taws xob mus nrawm dua hauv axons uas yog insulated nrog myelin. Myelin, tsim los ntawm glial txhawb lub hlwb, qhwv ib ncig ntawm axons thiab pab cov hluav taws xob tam sim no ntws hauv axon (ib yam li qhwv daim kab xev nyob ib ncig ntawm cov dej xau.hose yuav pab dej ntws los hose).
