Neuroglia . Muaj yog six hom neuroglia - plaub nyob rau hauv nruab nrab paj hlwb thiab ob nyob rau hauv lub PNS. Cov no glial ua cov hlwb muaj feem xyuam nrog ntau kev ua haujlwm tshwj xeeb sib nrug los ntawm kev txhawb nqa ntawm cov neurons. Neuroglia Hauv CNS muaj xws li astrocytes, microglial hlwb, ependymal hlwb thiab oligodendrocytes.
Tsis tas li ntawd, 6 hom Neuroglia yog dab tsi?
Muaj rau hom neuroglia, txhua tus muaj cov haujlwm sib txawv:
- Astrocyte.
- Oligodendrocytes.
- Microglia.
- Ependymal ntawm tes.
- Xov tooj ntawm tes.
- Schwann ntawm tes.
Tsis tas li, dab tsi yog ob hom Neuroglia pom hauv PNS? Muaj ob hom neuroglia hauv lub paj hlwb (PNS): Schwann hlwb thiab satellite hlwb . Schwann hlwb muab myelination mus rau peripheral cov neurons . Functionally, lub cov cell zoo ib yam li cov oligodendrocytes ntawm lub hauv paus paj hlwb (CNS).
Ua li no, 5 hom glial cells yog dab tsi?
Hom glial cells muaj xws li oligodendrocytes, astrocytes, ependymal hlwb , Schwann hlwb , microglia, thiab satellite hlwb.
Neuroglia yog dab tsi thiab lawv lub luag haujlwm yog dab tsi?
Neuroglia . Cov hlwb uas tsim myelin, tiv thaiv, txhawb nqa, thiab tswj kev sib npaug hauv koj lub paj hlwb tau hu ua glial ua hlwb. Lawv kuj feem ntau hu ua neuroglia thiab txawm ntau yooj yim glia. Hauv cov ntsiab lus ntxaws ntxiv, neuroglia yog cov cell hauv koj lub paj hlwb uas tsis yog neurons.
