Nervous system receptor types Flashcards
Increases heart rate at SA node
Sympathetic B1
Increases AV nodal conduction
Sympathetic B1
Increases contractility of the heart
Sympathetic B1
Decreases heart rate at SA node
Parasympathetic muscarinic
Decreases AV nodal conduction
Parasympathetic muscarinic
Decreases atrial contractility
Parasympathetic muscarinic
Constricts vascular smooth muscle of skin and visceral organs
Sympathetic A1
Dilates skeletal muscle vasculature
Sympathetic B2
Constricts skeletal muscle vasculature
Sympathetic A1
Dilates bronchioles
Sympathetic B2
Constricts bronchioles
Parasympathetic muscarinic
Relaxes smooth muscle of wall of GI tract
Sympathetic A2, B2
