Qhov sib txawv tseem ceeb ntawm kev xav thiab lub paj hlwb parasympathetic yog lub paj hlwb uas muaj lub siab xav ua lub luag haujlwm los tswj lub cev cov lus teb rau kev pom kev raug mob thiab kev txhawb nqa "sib ntaus lossis ya" cov lus teb thaum lub paj hlwb parasympathetic yog lub luag haujlwm rau kev tswj lub cev. homeostasis thiab lub cev "so-thiab-digest" teb.

Lub paj hlwb autonomic yog ib qho kev tswj hwm tus kheej uas tuaj nyob rau hauv lub paj hlwb peripheral. Yog li ntawd, nws yeej tswj hwm qhov chaw sab hauv ntawm lub cev los ntawm kev sib pauv cov lus txib ntawm lub paj hlwb peripheral thiab cov kab mob hauv nruab nrog cev txhawm rau tswj hwm lub cev tseem ceeb. Tsis tas li ntawd, muaj ob qhov kev faib loj hauv lub paj hlwb autonomic. Lawv yog; sympathetic paj hlwb thiab parasympathetic paj hlwb. Ob lub tshuab feem ntau ua rau tib lub cev thiab tsim kom muaj peev xwm ua tau zoo ib yam, tab sis lawv txoj haujlwm sib txawv thiab tawm tsam ib leeg.

Sympathetic Nervous System yog dab tsi?

Sympathetic nervous system yog ib qho ntawm ob feem ntawm lub paj hlwb autonomic. Nws tsim los ntawm lub paj hlwb ua los ntawm luv luv preganglionic axons uas txuas mus rau ganglia nyob ze ntawm lub thoracic thiab lumbar cheeb tsam ntawm tus txha caj qaum thiab ntev postganglionic neurons txuas los ntawm ganglia mus rau lub cev. Li no, cov fibers ntawm sympathetic efferent neurons kuj hu ua thoracolumbar outflow.

Daim duab 01: Sympathetic Nervous System

Lub luag haujlwm tseem ceeb ntawm lub paj hlwb kev xav yog npaj lub cev rau cov xwm txheej xwm txheej ceev thiab tsim kom muaj kev sib tw ceev kom tsis txhob muaj kev phom sij. Hauv cov lus yooj yooj yim, lub paj hlwb muaj lub siab xav tswj lub cev "sib ntaus lossis ya" cov lus teb thaum muaj xwm txheej hem.

Parasympathetic Nervous System yog dab tsi?

Parasympathetic lub paj hlwb muaj xws li preganglionic axons uas yog cov kab mob sib txuas hauv nruab nrog cev hauv thaj chaw cranial thiab sacral ntawm tus txha caj qaum, thiab luv luv postganglionic neurons txuas los ntawm ganglia mus rau lub cev. Yog li, cov fibers ntawm parasympathetic efferent neurons kuj hu ua craniosacral outflow.

Ntxiv mus, Acetylcholine yog cov neurotransmitter ntawm lub davhlau ya nyob twg synapses hauv lub paj hlwb. Cov txheej txheem no yog lub luag haujlwm los tswj cov dej num xws li "so- thiab - zom" lossis "paub- thiab- yug" uas tshwm sim thaum lub cev so.

Dab tsi zoo sib xws ntawm Sympathetic thiab Parasympathetic Nervous System?

  • Sympathetic thiab Parasympathetic Nervous System yog ib feem ntawm lub paj hlwb autonomic.
  • Tsis tas li, ob leeg koom nrog lub paj hlwb peripheral.
  • Thiab, lawv yog lub luag haujlwm rau cov lus teb tsis txaus ntseeg ntawm lub cev.

Qhov txawv ntawm Sympathetic thiab Parasympathetic Nervous System yog dab tsi?

Sympathetic thiab Parasympathetic Nervous System yog ob qhov tseem ceeb ntawm lub paj hlwb. Qhov sib txawv ntawm kev xav thiab parasympathetic paj hlwb yog tias lub paj hlwb ua haujlwm los txhawb lub cev kev sib ntaus sib tua-lossis-flight teb thaum parasympathetic paj hlwb ua haujlwm los tswj cov homeostasis ntawm lub cev.

Cov infographic hauv qab no qhia ntau qhov tseeb txog qhov sib txawv ntawm kev xav thiab parasympathetic paj hlwb.

Summary – Sympathetic vs Parasympathetic Nervous System

Lub cev lub paj hlwb muaj xws li ob lub paj hlwb tseem ceeb uas yog lub paj hlwb sympathetic thiab parasympathetic paj hlwb. Qhov system no tswj cov haujlwm ntawm lub cev thiab tswj qee cov leeg. Lub sympathetic paj hlwb tswj lub cev thaum muaj kev hem thawj. Hauv cov lus yooj yim, nws tswj lub cev "sib ntaus lossis ya" cov lus teb. Ntawm qhov tod tes, lub paj hlwb parasympathetic tswj cov haujlwm "so thiab zom" ntawm lub cev. Qhov no yog qhov sib txawv tseem ceeb ntawm sympathetic thiab parasympathetic paj hlwb.
