Cov hlab ntsha nruab nrab nkag mus rau sab xub ntiag ntawm caj npab ntawm lub cubital fossa. Hauv caj npab, cov hlab ntsha txav mus los ntawm flexor digitorum profundus thiab flexor digitorum superficialis nqaij.
Cov lus nug tseem yog, qhov nruab nrab ntawm cov hlab ntsha khiav mus qhov twg?
Median hlab ntsha . Nyob rau sab caj npab thiab ze ntawm lub xub pwg, lub nruab nrab paj hlwb ceg tawm ntawm lub brachial plexus. Nws pib spans qhov ntev ntawm sab caj npab, raws li nws khiav ib chav kawm sib luag rau cov hlab ntsha brachial. Ib feem ntawm nws txoj hauv kev npog sab nruab nrab ntawm caj npab, ze ob leeg biceps brachii thiab brachialis leeg.
Qhov thib ob, dab tsi yog qhov nruab nrab paj hlwb innervate? Sab xub ntiag ntawm lub xub pwg Thenar eminence Lumbricals ntawm tes
Yog li ntawd, cov leeg twg yog tswj los ntawm cov hlab ntsha nruab nrab?
Innervation. Cov hlab ntsha nruab nrab yog cov hlab ntsha loj sab hauv thiab muab khoom rau flexor cov leeg hauv caj npab tshwj tsis yog flexor carpi ulnaris thiab ulnar lub taub hau ntawm flexor digitorum profundus , uas yog muab los ntawm cov hlab ntsha ulnar. Nws kuj tseem muab cov leeg nqaij tom qab ntxiv rau radial ob lub lumbricals.
Puas yog lub paj hlwb nruab nrab lossis lub cev muaj zog?
Cov hlab ntsha nruab nrab yog ib ntawm tsib lub hauv paus loj lub hauv paus pib los ntawm brachial plexus thiab muab lub cev muaj zog thiab kev xav innervation rau qhov chaw ntawm lub hauv pliaj thiab tes.

Dab tsi yog qhov nruab nrab nruab nrab txhim kho rau?
Thaum lub sijhawm embryonic kev txhim kho, lub nruab nrab lub paj hlwb (tseem hu ua mesencephalon) tshwm sim los ntawm ob lub vesicle ntawm cov hlab ntsha neural, thaum sab hauv ntawm lub raj no dhau los ua lub paj hlwb. Nws tsis faib mus rau lwm qhov chaw hauv hlwb
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
Vim li cas cov hlab ntshav nruab nrab nruab nrab siv rau venipuncture?
Nws muaj feem cuam tshuam nrog chaw kho mob raws li nws tau siv tas li rau venipuncture (noj ntshav) thiab ua qhov chaw rau txhaj tshuaj cannula. Nws txuas cov basilic thiab cephalic leeg thiab ua qhov tseem ceeb thaum siv lub siab. Nws nyob hauv qhov cub fossa superficial mus rau kev ua haujlwm aponeurosis
Cov hlab ntsha hauv lub ntsws txawv li cas ntawm cov hlab ntsha hauv nruab nrog cev?
Cov hlab ntsha. Cov hlab ntsha hauv lub ntsws nqa cov ntshav oxygen tsawg los ntawm txoj hlab ntshav ntawm lub plawv mus rau lub ntsws. Cov hlab ntsha hauv lub cev thauj cov ntshav oxygenated los ntawm sab laug ventricle ntawm lub plawv mus rau tag nrho lub cev. Cov leeg
