Nyob rau hauv cov nyhuv ntawm no lawm yog zoo li tus txheej txheem, ua nyob rau hauv qhib rua ntawm lub sympathetic paj fibers. Yog li muaj ib tug tej yam nyob rau hauv lub A- thiab b-adrenergic receptors.

Raws li ib tug tshwm sim, tiam ntawm adrenaline nyob rau hauv tib neeg lub cev qhia vasoconstriction nyob rau hauv daim tawv nqaij, nyob rau hauv lub plab kab noj hniav thiab qog ua kua. Tab sis hais tias yog tsis yog txhua txhua. Hlab ntsha nyob rau hauv lub hlwb, on qhov tsis tooj, yuav expanding. Tom qab ntawd nws cim nce nyob rau hauv cov ntshav siab.

Theem adrenaline ntxim rau cov ntshav siab

Muaj plaub lub ntsiab theem lawm cawv rau cov ntshav siab. Ntawm lawv yog cov:

1. Lub plawv. Nyob rau hauv cov ntaub ntawv no, excitation b _1- adrenoceptors. Raws li ib tug tshwm sim, muaj ib qho kev nce nyob rau hauv mob cov zis thiab ib qho kev nce nyob rau hauv systolic cov ntshav siab.
2. Vagal. Qhov no theem raws li qhov ua kom ntawm cov me nyuam yaus ntawm tus vagus paj. Nws yog yus, raws li ib tug txoj cai, ntshav siab.
3. Vascular pressor. Qhov no theem yog txuam nrog rau cov excitation thiab _1- thiab _2-adrenergic receptors zoo li. Muaj ntaus cim tsuj ntawm peripheral vasopressor dab vagal theem. Nyob rau hauv no ntshav siab nws sawv rov qab.
4. Depressor-vascular. Rau ntawm no theem nce ua si b _2- adrenaretseptorov. Vim li no, muaj yog tsis tshua muaj ntshav siab.

Crank: hormone hauj lwm

tib neeg adrenaline yog txawv los ntawm cov khoom cua tshuaj. Txawm li cas los, lawv cov nyhuv ntawm lub cev sib npaug. Txawv rau adrenaline hnov mob tus mob. Tom qab tag nrho, lawv yog cov tag sib txawv adrenergic receptors. Piv txwv li, so ntawm bronchial tus nqaij thiab hnyuv tshwm sim thaum b ₂ -adrenoceptor stimulation, thiab cov menyuam kawm ntawv expansion - thaum ib tug ₁ -adrenoceptor stimulation.

Cov teebmeem ntawm adrenaline, uas yog nyob rau tib neeg lub cev, yog tseem nyob ntawm ntau yam. Tsis txhob hnov qab tias qhov no yog ib tug catabolic lawm.

Yog li ntawd yog dab tsi adrenaline? Kws txawj attribute nws kuj yuav kontrinsulyarnyh. Epinephrine yog tau lug txhim khu gluconeogenesis thiab glycogenolysis. Cov no ib tug ruamqauj ntawm tag nrho cov dab rau ua thiab glycogen nyob rau hauv lub siab thiab nyob rau hauv skeletal leeg. Nyob rau tib lub sij hawm tej lub capture thiab kev puas tsuaj ntawm qabzib. Vim li no, lub glycolytic enzymes tshuab txais.

Nws yog ib nqi sau cia hais tias lub hormone adrenaline, lub luag hauj lwm thiab kev khiav dej num ntawm cov uas tau ntev tau kawm, thiaj li muaj muaj roj synthesis thiab yeej txhawb nws degradation. Yog hais tias lub concentration ntawm no substance yog heev siab heev, thiab txawm enhanced protein catabolism nyob rau hauv tib neeg.

teeb meem los

Cov tshuaj muaj ib tug zoo feem nyob rau hauv kev kawm ntawm lub skeletal leeg. Qhov no tej khoom vaj tse yog ib qho tseem ceeb thaum cov ntaub ntawv uas qaug zog. Txawm li cas los, raws li qhov raug ntawm adrenaline nyob rau ntaub cim ib co kev hloov lub sij hawm. Feem ntau zog skeletal leeg thiab myocardium. Nws yog ib yam ntawm cov adaptation mus rau lub qhov kev nyuaj siab thiab siab lub cev loads.

Nyob rau hauv tas li ntawd, cov kho kom zoo protein catabolism, nqaij loj thiab lub dag lub zog txo. Raws li ib tug tshwm sim ntawm heev raug rau ib tug neeg muaj peev xwm poob phaus ruaj. Ib tug zoo xws li cov phenomenon muaj tshwm sim nrog nyuaj siab. Cov tshuaj yeeb dej caw muaj feem xyuam rau lub hauv paus poob siab system. Raws li ib tug tshwm sim, nws yog ua tau rau kom lub sij hawm ntawm wakefulness, puas siab puas ntsws zog thiab kev ua si.
