Lub dermis feem ntau yog tsim los ntawm cov ntaub so ntswg sib txuas tsis sib xws uas tau muab faib ua ob txheej : cov ntaub ntawv txheej thiab reticular txheej.
Tom qab ntawd, txheej txheej ntawm daim tawv nqaij puas qab haus huv nyob qhov twg?
Lub dermis yog nruab nrab txheej ntawm peb txheej tawv nqaij . Nws yog nyob nruab nrab ntawm daim tawv nqaij thiab cov ntaub so ntswg subcutaneous. Nws muaj cov ntaub so ntswg sib txuas, cov hlab ntshav, cov roj thiab cov qog hws, cov hlab ntsha kawg, thiab cov plaub hau.
Puas yog daim tawv nqaij puas muaj cov hlab ntshav?
Cov daim tawv nqaij yog qhov nyias, txheej txheej ntawm daim tawv nqaij uas pom tau rau lub qhov muag thiab ua haujlwm los muab kev tiv thaiv rau lub cev. Nws ua tsis muaj ib yam cov ntshav thiab yog, yog li ntawd, nyob ntawm daim tawv nqaij, txheej ntawm daim tawv nqaij hauv qab nws, txhawm rau nkag mus rau cov as -ham thiab pov tseg pov tseg.

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 peb thiaj sau cov ntshav los ntawm cov hlab ntsha thiab tsis yog los ntawm cov hlab ntsha?
