Autonomic tshee system, nyob rau hauv vertebrates, ib feem ntawm lub tshee cov kab ke uas tswj hwm thiab tswj hwm cov kabmob sab hauv yam tsis muaj kev paub paub lossis siv zog los ntawm lub cev. Cov autonomic tshee system muaj ob pawg antagonistic paj hlwb , cov khuv xim thiab parasympathetic tshee tshuab.
Tsis tas li ntawd, dab tsi yog suav nrog hauv autonomic paj hlwb?
Cov autonomic paj hlwb yog ib feem ntawm qhov lub paj hlwb uas muab cov khoom nruab nrog cev, suav nrog cov hlab ntsha, plab, hnyuv, siab, raum, zais zis, qhov chaw mos, lub ntsws, cov menyuam kawm ntawv, lub plawv, thiab tawm hws, salivary, thiab digestive qog. Cov autonomic paj hlwb muaj ob txoj kev sib faib tseem ceeb: Txaus siab.
Ib sab saum toj no, dab tsi yog qhov autonomic paj hlwb innervate? Cov autonomic paj hlwb innervates cov nqaij ntshiv ntawm cov hlab ntsha, digestive qhov system , zais zis thiab urethra, sab hauv cov hlab ntsha, cov leeg plawv, hws thiab lacrimal qog, thiab adrenal medulla. Cov autonomic paj hlwb muaj peb ceg ntoo: muaj kev khuv leej, mob siab rau, thiab nkag siab [1, 2, 3, 4].
Ib yam li ntawd, nws tau nug, dab tsi yog lub zog ntawm lub paj hlwb thiab nws tswj hwm dab tsi?
Cov autonomic paj hlwb ( ANS ) tswj kev ua haujlwm ntawm peb lub cev nruab nrog cev (viscera) xws li lub plawv, plab thiab hnyuv. Cov ANS yog ib feem ntawm cov khoom siv sab nraud lub paj hlwb thiab nws kuj tswj qee cov leeg hauv lub cev.
Dab tsi yog lwm lub npe rau lub cev tsis muaj zog?
Teb thiab Piav Qhia: Lwm lub npe rau autonomic paj hlwb yog visceral lub cev muaj zog qhov system.

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. 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
Dab tsi yog cov hlab ntsha tseem ceeb ntawm cov hlab ntsha?
Cov hlab ntsha, cov hlab ntsha thiab lymphatic system yog cov hlab ntsha tseem ceeb hauv lub cev circulating system. parasympathetic - lub luag haujlwm rau vasoconstriction
