Muaj rau hom neuroglia, txhua tus muaj cov haujlwm sib txawv:
- Astrocyte.
- Oligodendrocytes.
- Microglia.
- Ependymal ntawm tes .
- satellite ntawm tes .
- Schwann ntawm tes .
Ib yam nkaus, tib neeg nug, 6 hom Neuroglial cells yog dab tsi thiab lawv lub luag haujlwm yog dab tsi?
Muaj yog six hom neuroglia - plaub nyob rau hauv nruab nrab paj hlwb thiab ob nyob rau hauv lub PNS. Cov glial hlwb koom nrog ntau yam tshwj xeeb kev ua haujlwm sib nrug los ntawm kev txhawb nqa ntawm cov neurons. Neuroglia hauv CNS suav nrog astrocytes, microglial hlwb , ependymal sib hlwb thiab oligodendrocytes.
Zoo sib xws, muaj pes tsawg hom Neuroglial cells muaj? Muaj peb hom ntawm glial cells hauv lub hauv paus nruab nrab lub paj hlwb: astrocytes, oligodendrocytes, thiab microglial cells (Daim duab 1.4A-C). Astrocytes, uas tau txwv rau lub hlwb thiab qaum qaum, muaj cov txheej txheem hauv zos uas muab cov hlwb zoo li lub hnub qub (li no lub npe "astro").
Ib yam li ntawd, nws tau nug, dab tsi yog hom loj ntawm glial hlwb?
Glial hlwb muaj ntau tshaj hom xov tooj nyob rau hauv lub hauv paus paj hlwb. 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 yog cov hlwb hauv lub paj hlwb uas txhawb nqa neurons. Koj lub hauv nruab nrab thiab cov hlab ntsha hauv nruab nrog cev nyob ntawm qee cov cell uas yog cov yam ntxwv tsis zoo ntawm lub paj hlwb. 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.

Qhov sib txawv ntawm tus pab T cells thiab cytotoxic T cells yog dab tsi?
T hlwb yog li ntawd hu ua vim lawv feem ntau tsim nyob rau hauv lub thymus. Raws li cov npe hais tias pab T hlwb 'pab' lwm lub hlwb ntawm lub cev tiv thaiv kab mob, thaum cytotoxic T hlwb tua cov kab mob kis kab mob thiab qog. Tsis zoo li cov tshuaj tiv thaiv kab mob, TCR tsis tuaj yeem khi cov tshuaj tiv thaiv ncaj qha
Lub luag haujlwm ntawm T cells thiab B cells yog dab tsi?
T cells koom nrog hauv kev tiv thaiv kab mob ntawm tes, qhov B hlwb feem ntau yog lub luag haujlwm rau kev tiv thaiv kev dag ntxias (hais txog cov tshuaj tiv thaiv). Kev ua haujlwm ntawm T hlwb thiab B hlwb yog kom paub txog cov 'tsis yog tus kheej' antigens, thaum lub sijhawm ua haujlwm hu ua antigen nthuav qhia
Dab tsi yog qhov sib txawv ntawm glial cells thiab lawv cov haujlwm?
Hom Glia Glial hlwb ntawm (a) hauv nruab nrab paj hlwb muaj xws li oligodendrocytes, astrocytes, ependymal hlwb, thiab microglial hlwb. Oligodendrocytes tsim lub myelin sheath ncig axons. Astrocytes muab cov as -ham rau cov neurons, tswj hwm lawv ib puag ncig sab nraud, thiab muab kev txhawb nqa yam ntxwv
Muaj pes tsawg hom glial cells muaj?
peb hom Ib yam li ntawd, hom glial hlwb yog dab tsi? Kev Txhais Lus Kho Mob ntawm Glial cell Glial cell muaj ntau tshaj hom xov tooj nyob rau hauv lub hauv paus paj hlwb. Hom glial cells muaj xws li oligodendrocytes, astrocytes, ependymal hlwb , Schwann hlwb , microglia, thiab satellite hlwb .
4 CNS glial cells yog dab tsi?
Piv txwv ntawm plaub hom glial hlwb pom nyob rau hauv lub hauv paus paj hlwb: ependymal hlwb (lub teeb liab), astrocytes (ntsuab), microglial hlwb (dub liab), thiab oligodendrocytes (lub teeb xiav)
