Direct Effects of Autonomic Nerve Stimulation Flashcards
Eye
ciliary muscle - sympathetic activity
relaxation for far vision (B2)
Eye
Radial muscle, iris - sympathetic activity
contraction (a1)
Heart
SA node - sympathetic activity
increase HR (B1>B2)
Heart
Atria - sympathetic activity
increase contractility and conduction velocity (B1>B2)
Heart
AV Node - sympathtetic activity
increase in automaticity and conduction velocity (B1>B2)
Heart
His-Purkinje system - sympathetiac activity
increase in automaticity and conduction velocity (B1)
Heart
Ventricle - Sympathetic activity
increase in contractility, conduction velocity, automaticity and rate of idoventricular pacemakers (B1)
Blood vessels - sympathetic activity
constriction=alpa-1…. in some cases alpha-2
dilation= Beta 2
Lung
Tracheal and bronchial smooth muscle - sympathetic activity
relaxation (B2)
Lung
bronchial glands - sympathetic activity
decreased secretion =alpha 1
increased secretion = beta 2

decrease (usually) (a1, a2, b1, b2)
Stomach
Sphincters - sympathetic activity
contraction (usually) (alpha 1)
Stomach
secretion - sympathetic activity
