Adrenergic lawv. Adrenergic qhov system • Adrenergic kis tau tus mob - Noradrenaline/ Norepinephrine: Nws yog tus xa tawm ntawm postganglionic qhov chaw sib nkag siab (tshwj tsis yog cov qog hws, cov hauv paus plaub hau thiab qee cov vasodilator fibers) thiab hauv qee thaj tsam ntawm lub hlwb.
Tom qab ntawd, cov adrenergic receptors ua dab tsi?
Cov adrenergic receptors lossis adrenoceptors yog chav kawm ntawm G protein-txuas ua ke receptors uas yog lub hom phiaj ntawm ntau catecholamines zoo li norepinephrine (noradrenaline) thiab epinephrine (adrenaline) tsim los ntawm lub cev, tab sis kuj muaj ntau yam tshuaj xws li beta blockers, β2 agonists thiab cov kws kho mob pom zoo kom ua raws li cov lus pom zoo los ntawm kws kho mob2 agonists, uas yog siv los kho siab
Ib tus kuj tseem yuav nug, qhov twg muaj adrenergic synapses pom hauv lub cev? Adrenergic Neuron. Adrenergic neurons zais norepinephrine thiab yog pom nyob rau hauv ob qho tib si hauv nruab nrab thiab autonomic lub paj hlwb. Nyob rau hauv autonomic fibers, adrenergic neurons tsuas yog tshwj xeeb pom hauv postganglionic neurons ntawm kev mob siab rau lub paj hlwb.
Kuj nug yog, qhov sib txawv ntawm adrenergic thiab cholinergic yog dab tsi?
Lub ntsiab sib txawv ntawm ob yog lawv cov neurotransmitters. Rau cov cholinergic kab, acetylcholine (ACh) yog siv thaum lub adrenergic kab ua rau siv norepinephrine lossis epinephrine (tseem hu ua adrenaline); tsis xav li cas adrenergic kab tau los ua lub npe xws li vim tias adrenaline koom nrog.
Puas yog adrenergic txaus siab?
Adrenergic tshuaj txhawb lub paj hlwb hauv koj lub cev khuv xim lub paj hlwb (SNS). Adrenergic cov tshuaj muaj cov qauv zoo ib yam li cov xa xov tshuaj uas koj lub cev tsim thaum lub sijhawm muaj kev ntxhov siab, xws li epinephrine thiab norepinephrine.

Kab mob sib kis thiab kab mob sib kis yog dab tsi?
Kab Mob Sib Kis: Kev kis tus kabmob uas tawm tsam ntau tus tib neeg nyob rau tib lub sijhawm thiab tuaj yeem sib kis tau los ntawm ib lossis ntau lub zej zog. Pandemic: Thaum muaj kev kis mob thoob plaws ntiaj teb. Kab mob sib kis: Kab mob uas koj tuaj yeem kis tau. Lawv sib txuas lus tau
Dab tsi yog qhov piv txwv ntawm cov tshuaj adrenergic?
Piv txwv ntawm cov tshuaj adrenergic uas tsuas yog khi rau alpha-1 receptors yog phenylephrine, oxymetazoline. Xaiv cov tshuaj receptor alpha-2 suav nrog methyldopa thiab clonidine. Qhov tseem ceeb beta-1 tshuaj xaiv yog dobutamine. Thaum kawg, beta-2 cov tshuaj xaiv yog bronchodilators, xws li albuterol thiab salmeterol
Dab tsi yog hom kev sib kis hauv kev sib kis?
Kev sib kis, kev kis tus kab mob sib kis los ntawm ib tus neeg mus rau lwm tus (txawm los ntawm kev sib cuag ncaj qha, xws li hauv zaj duab xis no - txham lossis hnoos lossis kov ib lub qhov ntswg lossis qhov ncauj, tom qab ntawd ib qho chaw zoo li lub rooj zaum lossis lub qhov rooj uas lwm tus neeg ces kov - lossis kis tau tus mob. los ntawm qhov nruab nrab vector zoo li
Dab tsi yog qhov txawv ntawm ER ntxhib thiab du ER Dab tsi yog ER ua qhov sib txawv hauv txhua kis?
Ob qho tib si du thiab ntxhib endoplasmic reticulum pab hauv kev tsim thiab khaws cov proteins Qhov sib txawv tseem ceeb yog tias ib qho muaj ribosomes rau nws thiab lwm yam tsis. Rough ER zoo li cov nplooj ntawv. RER sib sau ua (ua) thiab ntim cov protein. RER tau txuas nrog lub nuclear membrane
