Cov hlab ntsha basilar (BA) ua haujlwm tseem ceeb rau cov ntshav ntws los ntawm cov hlab ntsha tom qab. Nws muab khoom ncaj nraim lub hlwb thiab cerebellumthiab muab cov ntshav ntws mus rau thalami thiab nruab nrab ntawm lub cev thiab lub parietal lobes.
anterior vestibular artery yog dab tsi?
Cov hlab ntsha vestibular anterior yog cov hlab ntsha me me uas muab cov utricle, superior saccule, thiab ampulae ntawm anterior thiablateral semicircular canals (Kim et al, 1999). Cov hlab ntsha labyrinthine yog cov hlab ntsha kawg, thiab yog li ntawd tej zaum yuav muaj kev phom sij ntau dua li lwm yam kev ncig.
Lub auditory artery yog dab tsi?
Cov hlab ntsha labyrinthine, tseem hu ua auditory artery lossis internal auditory artery, yog cov hlab ntsha ntev thiab cov hlab ntsha uas yog cov hlab ntsha tseem ceeb rau lub vestibular apparatus thiab cochlea. Nws kuj vascularizes lub VII thiab VIII cranial qab haus huv.

Cov hlab ntsha nyob qhov twg?
Lub cev qis qis. Cov hlab ntsha (hauv liab) yog cov hlab ntsha uas xa cov ntshav mus rau lub cev. Cov leeg (hauv xiav) yog cov hlab ntsha uas rov qab mus rau lub plawv. Cov leeg sib sib zog nqus, nyob nyob rau hauv nruab nrab ntawm ob txhais ceg ze ntawm cov pob txha ceg, yog cov leeg.
Phrenic hlab ntsha nyob qhov twg?
Cov hlab ntsha phrenic originates los ntawm anterior rami ntawm C3 mus txog C5 paj hlwb thiab muaj lub cev muaj zog, kev xav, thiab kev xav paj hlwb. Nws muab tag nrho lub cev muaj zog innervation rau lub diaphragm thiab kev hnov qab mus rau hauv nruab nrab cov leeg hauv nruab nrab cov leeg Lub hauv paus leeg ntawm lub diaphragm yog ib qho nyias nyias tab sis muaj zog aponeurosis situated me ntsis anterior mus rau lub vault tsim los ntawm cov leeg, ua rau nyob rau hauv nt
Cov hlab ntsha gonadal nyob qhov twg?
Cov hlab ntsha gonadal yog cov hlab ntsha uas feem ntau yog los ntawm lub plab aorta ntawm qib thib ob lumbar vertebra. Hauv 5-20% ntawm cov neeg mob, cov hlab ntsha gonadal muaj lub hauv paus loj (zoo dua rau L2) thiab hauv 5-6% ntawm cov neeg mob nws tshwm sim los ntawm cov hlab ntsha loj lossis cov khoom siv raum.
Qhov twg cov hlab ntsha anastomoses tshwm sim hauv lub cev?
Anastomoses tshwm sim ib txwm nyob hauv lub cev hauv cov kab mob hauv lub cev, ua haujlwm rau cov ntshav khiav yog tias ib qho txuas raug thaiv lossis cuam tshuam lwm yam. Anastomoses nruab nrab ntawm cov hlab ntsha thiab nruab nrab ntawm cov leegua rau muaj ntau cov hlab ntsha thiab cov hlab ntsha, feem, ua haujlwm tib lub ntim ntawm cov ntaub so ntswg.
Puas yog cov hlab ntsha loj dua cov hlab ntsha?
Arterioles nqa ntshav thiab oxygen mus rau hauv cov hlab ntsha me tshaj plaws, cov hlab ntsha. Capillaries yog li ntawd small lawv tsuas pom tau nyob hauv lub tshuab tsom. Cov phab ntsa ntawm capillaries yog permeable rau oxygen thiab carbon dioxide.
