Lub lumbar splanchnic hlab ntsha tshwm sim los ntawm qib lumbar sab sauv thiab xaus nyob rau hauv qis dua mesenteric thiab hypogastric ganglia. Los ntawm cov kab mob prevertebral ganglia no, cov kab mob postganglionic muab cov khoom nruab nrog cev hauv plab, hauv plab thiab qis dua.
Ib yam li ntawd, koj tuaj yeem nug, qhov twg yog cov hlab ntsha splanchnic nyob?
Qhov loj dua splanchnic paj taug kev los ntawm lub diaphragm thiab nkag mus rau hauv plab kab noj hniav, qhov twg nws cov fibers sib txuas ntawm celiac ganglia. Cov paj hlwb contributes rau lub celiac plexus, ib tug network ntawm paj hlwb nyob nyob ib ncig ntawm qhov chaw ntawm lub cev celiac ceg ceg ntawm lub plab aorta.
Puas yog splanchnic paj hlwb sympathetic? Splanchnic qab haus huv yog ob sab visceral autonomic paj hlwb . Lub thoracic, lumbar thiab sacral splanchnic hlab ntsha yog txaus siab hauv kev ua haujlwm thaum lub plab splanchnic hlab ntsha yog parasympathetic.
Nyob rau hauv no yam, qhov twg splanchnic qab haus huv keeb kwm?
Qhov loj dua splanchnic hlab ntsha , tsim los ntawm myelinated preganglionic thiab visceral afferent fibers, feem ntau yog xav tias yuav muab thawj qhov kev xav innervation rau pancreas thiab proximal retroperitoneal visceral lug thiab feem ntau tshwm sim los ntawm thoracic sympathetic ganglia ntawm T5-9.
Lub paj hlwb splanchnic txhais li cas?
Cov splanchnic paj hlwb ua ke visceral paj hlwb ( paj hlwb uas pab txhawb rau sab hauv ntawm cov kabmob sab hauv), nqa cov xov paj ntawm lub paj hlwb uas tsis muaj zog (visceral efferent fibers) nrog rau cov leeg nqaij ntawm lub nruab nrog cev (visceral afferent fibers).
Pom zoo:
Cov hlab ntsha qis hauv cov hlab ntsha ntws mus rau qhov twg?
Brachiocephalic leeg
Cov hlab ntsha thiab cov hlab ntsha nyob qhov twg?
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
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
