: lub plasma daim nyias nyias ntawm ib lub axon Rau ib lub sij hawm luv luv tom qab qhov kawg ntawm lub paj hlwb impulse raws li ib tug paj hlwb, thaum lub axolemma tseem depolarized, ib tug thib ob stimulus, txawm li cas los muaj zog, yog tsis muaj peev xwm ua rau excite lub paj hlwb. -
Dab tsi yog qhov txawv ntawm axolemma thiab neurilemma?
Plasma membrane ncig lub paj hlwb hu ua axolemma. Neurilemma yog plasma daim nyias nyias ntawm Schwann hlwb uas nyob ib ncig ntawm myelinated paj fibers ntawm peripheral paj hlwb thiab tsis nyob rau hauv lub hauv paus paj hlwb vim tsis muaj myelin sheath vim tsis muaj Schwann hlwb.
Neural membrane ua dab tsi?
Lub paj hlwb yog qhov chaw uas feem ntau cov txheej txheem koom nrog hauv kev khaws cia thiab ua haujlwm tau tshwm sim Cov kev ua no yuav tsum muaj kev koom tes ntawm cov tshuaj tiv thaiv kab mob ntsig txog cov kab mob, uas koom nrog hauv cov protein / lipid pawg los pib ua cov txheej txheem molecular thiab teeb liab transduction.
Axoplasm ua dab tsi?
Axoplasm yog ib qho tseem ceeb rau tag nrho cov haujlwm ntawm cov neurons hauv kev nthuav tawm cov peev xwm los ntawm axon. Tus nqi ntawm axoplasm hauv axon yog qhov tseem ceeb rau cov cable zoo li cov khoom ntawm axon hauv txoj kev xav cable.
Neurolemma yog dab tsi?
Neurolemma (tseem neurilemma thiab sheath ntawm Schwann) yog txheej txheej ntawm paj hlwb nyob rau hauv lub paj hlwb peripheral. Nws yog nucleated cytoplasmic txheej ntawm schwann hlwb uas nyob ib ncig ntawm myelin sheath ntawm axons.
