Nyob rau hauv nruab nrab lub paj hlwb, axons yog myelinated los ntawm oligodendrocytes, yog li tsis muaj neurilemma. … Neurilemma ua haujlwm tiv thaiv rau cov paj hlwb peripheral. Cov paj hlwb puas tuaj yeem rov tsim dua yog tias lub cev ntawm tes tsis raug puas tsuaj thiab neurilemma tseem nyob tsis zoo.
CNS puas muaj neurilema?
Neurilemma yog tseem ceeb rau kev tiv thaiv thiab rov tsim dua cov paj hlwb. Myelin yog secreted los ntawm Schwann hlwb nyob rau hauv lub peripheral paj hlwb thiab oligodendrocytes nyob rau hauv lub hauv paus paj hlwb.
Neurolemma nyob qhov twg?
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.
Puas CNS axons muaj Neurolemma?
Hauv CNS, axons yog myelinated los ntawm oligodendrocytes, yog li tsis muaj neurolemma. Lub myelin sheaths ntawm Oligodendrocytes tsis muaj neurolemma vim tias ntau tshaj cytoplasm yog coj mus rau hauv nruab nrab ntawm Oligodendrocyte cell lub cev.
Puas neurilemma muaj nyob rau hauv myelinated neurons?
Neurilema tsuas yog muaj nyob rau hauv lub paj hlwb peripheral. Nws muaj nyob rau hauv ob leeg myelinated thiab non-myelinated fibers. Nws tsis tuaj nyob rau hauv lub hauv paus paj hlwb vim tsis muaj Schwann hlwb.
