Qhov sib txawv tseem ceeb ntawm adrenergic thiab cholinergic receptors yog tias adrenergic receptors yog G protein-coupled receptors uas khi rau cov neurotransmitters noradrenaline (norepinephrine) thiab adrenaline (epinephrine) thaum lub cholinergic receptors yog inotropic thiab metabobind receptors. acetylcholine neurotransmitters.
Lub paj hlwb autonomic yog ib qho tseem ceeb ntawm cov hlab ntsha hauv peb lub cev. Nws yog lub luag haujlwm los tswj cov kev ua uas tsis ua nrog kev paub txog lossis kev siv zog los ntawm lub cev. Piv txwv ntawm cov kev ua no yog ua pa, lub plawv dhia, ntshav siab, tso zis, plab zom mov, tso zis, lub cev kub, thiab lwm yam. Yog li ntawd, ob qho kev faib loj ntawm lub paj hlwb autonomic yog sympathetic nervous system thiab parasympathetic paj hlwb. Ob lub tshuab no siv cov neeg xa xov chemical lossis cov neurotransmitters los sib txuas lus hauv lub paj hlwb. Acetylcholine thiab norepinephrine yog ob hom tshuaj xa xov tseem ceeb uas zais los ntawm cov paj hlwb no.
Adrenergic Receptors yog dab tsi?
Adrenergic receptors yog cov receptors uas khi thiab teb rau noradrenaline (norepinephrine) thiab adrenaline (epinephrine). Cov receptors no yog G protein-coupled receptors feem ntau koom nrog lub paj hlwb sympathetic.
Daim duab 01: Adrenergic Receptors
Tsis tas li ntawd, muaj ob lub adrenergic receptors uas yog α-receptors Alpha 1 thiab 2) & β-receptors (beta 1, 2 thiab 3). Beta 2 receptors muaj kev sib raug zoo siab dua rau adrenaline thaum alpha receptors qhia tias muaj kev sib raug zoo dua rau noradrenaline. Ntawm cov receptors no, α1 & β1 yog lub luag haujlwm rau excitation thaum α2 & β2 yog lub luag haujlwm rau inhibition.
Cholinergic Receptors yog dab tsi?
Cholinergic receptors yog hom thib ob ntawm receptors siv nyob rau hauv lub paj hlwb autonomic. Cholinergic neurons tso acetylcholine. Cov receptors no yog inotropic thiab metabotropic. Thiab, lawv khi thiab teb rau acetylcholine thiab pab kev sib txuas lus.
Daim duab 02: Muscarinic Receptors
Ntxiv mus, cholinergic receptors koom nrog lub paj hlwb parasympathetic. Muaj ob hom cholinergic receptors uas yog muscarinic thiab nicotinic receptors. Muscarinic receptors nrhiav pom ntawm tag nrho cov kab mob visceral.
Dab tsi zoo sib xws ntawm Adrenergic thiab Cholinergic Receptors?
- Adrenergic thiab Cholinergic Receptors yog ob lub autonomic receptors.
- Lawv teb rau neurotransmitters.
- Ob leeg ua rau paj hlwb impulses.
Qhov txawv ntawm Adrenergic thiab Cholinergic Receptors yog dab tsi?
Adrenergic receptors ua haujlwm hauv lub paj hlwb sympathetic. Lawv khi rau adrenaline thiab noradrenaline. Ntawm qhov tod tes, cholinergic receptors ua haujlwm hauv lub paj hlwb parasympathetic. Lawv khi rau acetylcholine. Muaj ob lub ntsiab ntawm adrenergic receptors (alpha thiab beta) thaum muaj ob cholinergic receptors uas yog nicotinic thiab muscarinic. Cov nram qab no infographic nthuav tawm qhov sib txawv ntawm adrenergic thiab cholinergic receptors hauv daim ntawv tabuar.
Summary – Adrenergic vs Cholinergic Receptors
Adrenergic thiab cholinergic yog ob lub receptors hauv lub paj hlwb autonomic. Adrenergic receptors ua haujlwm rau lub paj hlwb sympathetic thaum cholinergic receptors ua haujlwm rau lub paj hlwb parasympathetic. Ntxiv mus, adrenergic thiab cholinergic receptors teb rau adrenaline / noradrenaline thiab acetylcholine feem. Qhov no yog qhov txawv ntawm adrenergic thiab cholinergic receptors.
