Myelin yog txheej txheej insulating, los yog sheath uas tsim nyob ib ncig ntawm cov hlab ntsha, suav nrog cov hauv hlwb thiab qaum qaum. Nws yog tsim los ntawm cov protein thiab fatty khoom. Qhov no myelin sheath tso cai rau hluav taws xob impulses kis tau sai thiab zoo raws cov paj hlwb.
piv txwv ntawm myelin yog dab tsi?
Myelination yog ib lo lus nyob rau hauv lub cev uas txhais tau tias yog txheej txheem ntawm kev tsim myelin sheath nyob ib ncig ntawm lub paj hlwb kom cov paj hlwb txav mus sai dua. Ib qho piv txwv ntawm myelination yog qhov tsim ntawm myelin nyob ib ncig ntawm axons ntawm lub cev…
Milenated txhais li cas?
: muaj myelin sheath myelinated paj fibers.
myelin lub luag haujlwm yog dab tsi?
Myelin Txhawb Kev Tshaj Tawm nrawm nrawm Nrog Axons Nws insulates lub axon thiab sib sau ua ke tshwj xeeb cov qauv molecular ntawm cov leeg ntawm Ranvier.
Yuav ua li cas yog tias koj tsis muaj myelin?
Thaum lub myelin sheath puas lawm, paj hlwb tsis ua hluav taws xob impulses ib txwmQee zaum cov paj hlwb kuj puas lawm. Yog tias cov ntaub qhwv tuaj yeem kho thiab rov tsim nws tus kheej, cov hlab ntsha ib txwm tuaj yeem rov qab los. Txawm li cas los xij, yog tias lub plhaub tau raug mob hnyav, cov paj hlwb hauv qab tuaj yeem tuag.
