Lawv pib los ntawm arachnoid cap hlwb , yog hlwb nyob rau hauv daim nyias nyias, kab laug sab web-zoo li daim nyias nyias uas npog lub hlwb thiab qaum qaum. Qee cov meningiomas pom nyob rau hauv ob sab hauv ob sab hauv lub venous sinuses ntawm lub hlwb thiab pob txha taub hau puag - qhov chaw nyob qhov twg. arachnoid cap hlwb muaj ntau tshaj
Ntawm no, arachnoid hlwb yog dab tsi?
Vertebral Kem thiab Spinal Meninges The arachnoid yog tsim los ntawm collagen thiab elastic fibers. Txheej sab nrauv ntawm arachnoid yog arachnoid thaiv ntawm tes txheej uas suav nrog ntim cov khoom siv hluav taws xob zoo hlwb . Cov pav ca hlwb tsis tuaj yeem nkag mus rau cov kua dej hauv lub paj hlwb vim muaj kev sib tshuam sib txuas ntawm qhov sib txuas.
Ib yam li ntawd, arachnoid granulations yog dab tsi thiab lawv ua li cas? Arachnoid granulation yog cov qauv uas muaj cov kua dej cerebrospinal (CSF) uas txuas mus rau hauv cov venous sinuses los ntawm kev qhib hauv dura mater thiab tso cai rau cov kua dej ntawm CSF los ntawm subarachnoid qhov chaw mus rau hauv cov hlab ntsha. Feem ntau lawv yog asymptomatic tab sis tau yuav symptomatic thaum loj txaus ua rau sinus occlusion.
Ib yam li ntawd, kev ua haujlwm ntawm arachnoid yog dab tsi?
Arachnoid mater: Txuas nrog dura mater ntawm sab ze rau CNS, txheej nruab nrab no suav nrog kev sib txuas ntawm cov fibers thiab collagen uas yog ib feem ntawm qhov kev tshem tawm uas pab tiv thaiv lub hlwb thiab tus txha caj qaum los ntawm kev cuam tshuam sai.
Dab tsi yog arachnoid mater tsim los ntawm?
qauv ntawm meninges … qhov chaw subarachnoid yog arachnoid , nyias nyias, pob tshab daim nyias nyias . Nws yog muaj los ntawm cov ntaub so ntswg thiab, zoo li pia niam , yog them los ntawm cov cell tiaj tus kuj xav tias yuav impermeable rau kua.

T cells thiab B cells ua haujlwm li cas?
Tom qab ntawd koj lub cev tuaj yeem tsim cov riam phom zoo tshaj plaws tiv thaiv cov neeg tawm tsam, uas tuaj yeem yog kab mob, kab mob lossis kab mob parasites. Lwm hom T-cells paub thiab tua cov kab mob uas muaj kab mob ncaj qha. Qee qhov pab B-cells ua cov tshuaj tiv thaiv kab mob, uas nthuav dav thiab khi rau antigens. T-cell (txiv kab ntxwv) tua kab mob qog noj ntshav (mauve)
Neuroglial cells yog dab tsi thiab lawv lub luag haujlwm yog dab tsi?
Cov hlwb uas tsim myelin, tiv thaiv, txhawb nqa, thiab tswj kev sib npaug hauv koj lub paj hlwb hu ua glial cells. Lawv kuj tseem raug hu ua neuroglia thiab txawm tias yooj yim dua glia. Hauv cov lus ntxaws ntxaws, neuroglia yog cov hlwb hauv koj lub paj hlwb uas tsis yog neurons
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 ependymal cells thiab lawv ua dab tsi?
Ependymal Cell. Ependymal cells yog ib hom tshwj xeeb ntawm cov epithelial cells uas ua kab ke ntawm lub paj hlwb ntawm lub paj hlwb thiab ua lub luag haujlwm tseem ceeb hauv kev tsim cov kua dej hauv lub paj hlwb
