Sib ntaus lossis Dav Hlau . Tsim cov sib ntaus-lossis-davhlau Cov lus teb, lub hypothalamus activates ob lub cev: lub paj hlwb sympathetic thiab adrenal-cortical system. Lub paj hlwb uas muaj kev nkag siab zoo siv txoj hauv kev paj hlwb los pib ua rau muaj kev cuam tshuam hauv lub cev, thiab cov qog adrenal-cortical siv cov hlab ntshav.
Yooj yim li ntawd, dab tsi tshwm sim rau lub hlwb thaum sib ntaus lossis ya dav hlau?
Dab tsi tshwm sim thaum lub sijhawm cov Sib ntaus-lossis-Dav Hlau Teb. Hauv kev teb rau qhov kev nyuab siab, lub cev kev xav hauv lub paj hlwb tau ua haujlwm vim qhov tso tawm sai sai ntawm cov tshuaj hormones. Cov paj hlwb ua rau lub siab xav ua rau cov qog adrenal ua rau tso tawm catecholamines, uas suav nrog adrenaline thiab noradrenaline.
Ib yam li ntawd, dab tsi tswj kev sib ntaus lossis kev ya davhlau? Lub sympathetic paj hlwb originates nyob rau hauv tus txha caj qaum thiab nws lub luag hauj lwm tseem ceeb yog mus qhib lub physiological hloov uas tshwm sim thaum lub sij hawm. sib ntaus sib tua los yog ya davhlau teb. Cov tshuaj no ntawm lub paj hlwb autonomic siv thiab ua kom tso tawm norepinephrine hauv cov tshuaj tiv thaiv.
Raws li, qhov twg ntawm lub paj hlwb yog lub luag haujlwm rau kev sib ntaus lossis ya dav hlau?
Amygdala yog ib ntawm ob qhov zoo ib yam li cov noob txiv ntoo ntawm cov nuclei nyob sib sib zog nqus hauv lub lobe sab hauv, uas ntawm lwm cov haujlwm, koom nrog hauv kev ntshai hauv koj lub xov tooj. lub hlwb . Cov qauv no yog lub luag haujlwm rau kev sib ntaus-lossis-dav hlau teb uas ua rau koj teb rau kev hem.
Vim li cas kuv kev sib ntaus lossis kev sib tw hauv dav hlau thiaj muaj zog?
Qhov no yog a siab qhov tseem ceeb rau kev tswj kev ntxhov siab. Kev sib ntaus-lossis-dav hlau teb yog txhais tau tias yuav tsum tau ua raws los ntawm kev ua haujlwm tas li. Nws tsis tsuas yog siv xwb cov zog tsim nyob rau hauv cov lub cev, nws metabolises (tawg) cov tshuaj hormones ntau dhau. Qib qis ntawm cov tshuaj hormones kev nyuab siab txhais tau tias ua rau lub cev thiab lub siab nqig.
