Txawm hais tias muaj ntau qhov sib txawv ntawm cov molecular lossis morphological sib txawv ntawm cov paj hlwb hauv PNS thiab CNS, cov txheej txheem ntawm myelin sheath thiab cov yam ntxwv ntawm electrophysiological yog qhov tseem ceeb tib yam. Puas yog tag nrho cov axons npog nrog myelin? No; lawv tuaj yeem yog myelinated lossis unmyelinated
Cov neurons twg tsis muaj myelin sheath?
Ib tug neuron uas tsis muaj myelin sheath nyob ib ncig ntawm lub axon. Lub unmyelinated neuron cuam tshuam rau ib qho ntawm cov neurons uas tsis muaj myelin sheath (ib lub plhaub rau kev ua haujlwm sai ntawm qhov muaj peev xwm ua tau).
Puas tag nrho cov neurons muaj myelin?
Txawm hais tias muaj ntau qhov sib txawv ntawm cov molecular lossis morphological sib txawv ntawm cov paj hlwb hauv PNS thiab CNS, cov txheej txheem ntawm myelin sheath thiab cov yam ntxwv ntawm electrophysiological yog qhov tseem ceeb tib yam. Puas yog tag nrho cov axons npog nrog myelin? No; lawv tuaj yeem yog myelinated lossis unmyelinated.
Pob neurons tsim myelin sheath?
Ua los ntawm lipids thiab cov proteins, myelin tau pom tom qab qhwv ncig cov axons ntawm neurons. … Hauv lub hauv paus paj hlwb (CNS) - lub paj hlwb thiab qaum qaum - cov hlwb hu ua oligodendrocytes qhwv lawv cov ceg zoo li txuas ntxiv nyob ib ncig ntawm axons los tsim myelin sheath.
Vim li cas qee cov neurons muaj myelin sheathing?
Myelin Sheath Functions
Myelin sheath lub luag haujlwm tseem ceeb yog muab kev rwb thaiv tsev rau cov axons ntawm cov neuron nws ncig. Qhov rwb thaiv tsev no muab kev tiv thaiv rau cov axons tib yam li cov xov hlau hluav taws xob muaj rwb thaiv tsev.
