Intracranial stenosis, tseem hu ua intracranial hlab ntsha stenosis, yog qhov nqaim ntawm ib qho cov leeg hauv lub hlwb, uas tuaj yeem ua rau mob stroke. Nruab nrab cerebral cov leeg (MCA), uas yog ceg loj tshaj plaws ntawm ICA. Vertebral cov hlab ntsha , uas muab ntshav mus rau thaj chaw tom qab ntawm lub hlwb.
Dhau li, cov hlab ntsha extracranial yog dab tsi?
Extracranial (sab nraum lub cranium, uas nyob hauv lub hlwb) sab hauv carotid cov leeg stenosis yog ib yam mob uas ib los yog ob qho tib si ntawm ob sab hauv carotid cov hlab ntsha , uas nqa cov ntshav mus rau lub hlwb, ua nqaim-feem ntau dhau los ntawm kev sib sau ntawm cov quav hniav hauv sab hauv sab hauv cov leeg.
Ib yam li ntawd, intracranial artery stenosis yog dab tsi? Intracranial stenosis yog ib tug nqaim cov leeg sab hauv lub hlwb. Kev tsim cov plaque (atherosclerosis) hauv lub cev cov leeg phab ntsa txo cov ntshav ntws mus rau lub hlwb. Kev kho mob txhawm rau txo qhov kev pheej hmoo ntawm mob hlab ntsha tawg los ntawm kev tswj lossis tshem tawm cov quav quav thiab los ntawm kev tiv thaiv ntshav khov.
Ib yam li ntawd, koj tuaj yeem nug, kab mob intracranial yog dab tsi?
Intracranial Vascular Kab mob . Intracranial cev kab mob (los yog stenosis) yog xav tias yuav suav txog li 10 feem pua ntawm tag nrho cov mob stroke thiab cov kev tawm tsam ischemic (TIAs). Nws yog qhov nqaim ntawm cov hlab ntsha ntawm lub hauv paus ntawm pob txha taub hau lossis sab hauv lub hlwb.
Yuav ua li cas tshwm sim thaum cov hlab ntsha hauv lub hlwb raug thaiv?
Ib qho ischemic stroke tshwm sim thaum cov hlab ntsha hauv lub hlwb ua thaiv . Ischemic ("is-skeem-ic") mob hlab ntsha tawg tshwm sim thaum cov leeg ntshav mus rau lub hlwb raug thaiv . Cov lub hlwb nyob ntawm nws cov hlab ntsha nqa cov ntshav tshiab los ntawm lub plawv thiab lub ntsws. Yog tias cov leeg tseem tshuav thaiv rau ntau tshaj li ob peb feeb, lub lub hlwb hlwb yuav tuag.

Dab tsi yog qhov txawv ntawm cov hlab ntsha thiab cov hlab ntsha capillaries?
Piav qhia: Cov hlab ntshav nqa ntshav nyob hauv siab los ntawm lub plawv mus rau cov kabmob thiab cov nqaij. Lawv cov phab ntsa feem ntau yog tuab dua li cov leeg. Capillaries yog qhov sib txuas ntawm cov hlab ntsha thiab cov leeg thiab me me heev, Cov ntaub so ntswg qee zaum pom tawm thiab rov nco qab los ntawm cov qog ntshav thiab rov qab los rau cov leeg ntshav
Cov hlab ntsha hlab ntsha thiab cov hlab ntshav muaj dab tsi?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Puas yog Neuroglia tsim cov hlab ntsha hauv cov hlab ntsha hauv nruab nrab cov hlab ntsha?
Muaj plaub hom neuroglia pom nyob hauv nruab nrab lub paj hlwb: Astrocytes - tswj cov ntshav lub hlwb teeb meem thiab khaws cov tshuaj ib puag ncig los ntawm kev siv cov ions rov qab thiab cov tshuaj xa xov mus rau lub cev. Oligodendrocytes - myelinate axons nyob rau hauv lub hauv nruab nrab lub paj hlwb thiab muab tag nrho cov txheej txheem txheej txheem
Dab tsi yog cov hlab ntsha thiab cov hlab ntsha capillaries?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Dab tsi yog cov hlab ntsha tseem ceeb ntawm cov hlab ntsha?
Cov hlab ntsha, cov hlab ntsha thiab lymphatic system yog cov hlab ntsha tseem ceeb hauv lub cev circulating system. parasympathetic - lub luag haujlwm rau vasoconstriction
