Tsis tas li ntawd, koj nyob qhov twg Auscultate brachial artery?
Cov brachial mem tes yog palpated saum lub kaum sab xis ntawm lub luj tshib ("antecubital fossa"). Ib pab pawg koom nrog tso lub mloog pob ntseg, nrog lub pob ntseg ntawm lub taub hau tig rau pem hauv ntej. Qhov kaw qhov kawg ntawm lub mloog pob ntseg yog sib tw, kom lub diaphragm thiab tsis yog lub tswb tau qhib.
Vim li cas kuv thiaj tsis hnov kuv cov hlab ntsha brachial?
Yog koj hnov tsis tau lub plawv dhia, sim nias me ntsis rau hauv koj txhais caj npab. Cov brachial leeg yog sib sib zog nqus hauv cov leeg, yog li nws tuaj yeem siv qee qhov maj mam ua rau hnov . Yog koj tseem ua tsis tau nrhiav tus mem tes, txav koj cov ntiv tes ncig hauv qhov cub fossa kom txog thaum koj hnov ib thump. Lub siab yuav tsum maj thiab lub teeb.

Txawm hais tias txoj hlab ntsha yog ib txwm ntseeg tias taug kev hauv qhov zawj ntawm qhov tsis zoo ntawm tus tav nrog rau cov hlab ntsha thiab cov leeg leeg, cov hlab ntsha kuj tseem tuaj yeem nyob nruab nrab ntawm cov tav. Cov paj hlwb intercostal nyob tob rau hauv cov leeg nqaij intercostal thiab sab nraud rau lub pleura
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

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
