Nws yog ua los ntawm ib tug nqaim los yog thaiv cov hlab ntsha . Qhov laj thawj tseem ceeb yog atherosclerosis, uas yog tsim los ntawm fatty deposits uas nqaim a cov hlab ntsha , feem ntau ib cov leeg . Qhov nqaim cov hlab ntsha txo cov kev ncig ntawm ntshav rau lub cev uas txuam nrog.
Ua raws li qhov no hauv kev xav, dab tsi ua rau cov hlab ntsha hauv lub hlwb nqaim?
Intracranial stenosis yog ib nqaim ntawm cov hlab ntsha sab hauv lub hlwb . Zoo ib yam li carotid stenosis hauv caj dab, nws yog ua los ntawm ib tug buildup ntawm plaque nyob rau hauv lub puab phab ntsa ntawm lub cov hlab ntsha . Plaque tuaj yeem roughen thiab deform cov leeg phab ntsa, ua ntshav clots los tsim thiab thaiv ntshav ntws mus rau lub hlwb.
Ib yam li ntawd, yog qhov nqaim ntawm cov hlab ntsha loj? Atherosclerosis (arteriosclerosis) Atherosclerosis yog qhov muaj peev xwm loj mob qhov twg cov hlab ntsha ua clogged nrog fatty tshuaj hu ua plaques, los yog atheroma. Tab sis tus mob feem ntau tuaj yeem tiv thaiv nrog kev noj qab haus huv hauv lub neej, thiab kev kho mob tuaj yeem pab txo kev pheej hmoo ntawm loj teeb meem tshwm sim.
Tsis tas li ntawd, yuav ua li cas thaum cov hlab ntsha nqaim?
Koj siab dua ntshav siab yog, qhov muaj feem ntau dua uas lub siab ntxiv tuaj yeem ua rau cov leeg tsis muaj zog tawg. Tsis tas li ntawd, cov nqaim koj cov hlab ntsha yog, qhov kev pheej hmoo ntau dua uas lawv tuaj yeem raug thaiv. Yog hais tias cov hlab ntsha tawg muab ib feem ntawm lub plawv, qhov chaw ntawm lub plawv cov leeg yuav tuag, ua rau lub plawv nres.
Cov hlab ntsha nqaim hu ua dab tsi?
Thaum no hardening tshwm sim, lub cov hlab ntsha kev paub a nqaim uas tuaj yeem ua rau nws nyuaj rau cov ntshav ntws. Qhov no yog dab tsi yog hu ua vascular stenosis , thiab nws cuam tshuam rau cov hlab ntsha ua rau lub hlwb, lub plawv, thiab ob txhais ceg feem ntau.

Dab tsi ua rau cov hlab ntsha hauv ob txhais ceg nqaim?
Qhov no feem ntau yog cov tsos mob ntawm cov hlab ntshav sab hauv, uas cov hlab ntsha uas muab cov ntshav rau koj txhais ceg tau nqaim, feem ntau vim yog atherosclerosis. Atherosclerosis tshwm sim thaum cov hlab ntsha tau tuab thiab txhav vim yog kev sib sau ntawm cov rog rog (cov quav) ntawm koj cov phab ntsa hlab ntshav
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.
