ANS: sympathetic vs parasympathetic Flashcards
Bain- body responses to symp vs parasymp stimuli
pupil
dilated – constricted
ciliary muscle
slight relaxation (far vision) —- constricted (near vision)
Nasal gland
vasoconstriction and slight secretion —— stimulation of copious secretion (containing many enzymes for enzyme-secreting glands)
lacrimal gland
vasoconstriction and slight secretion —— stimulation of copious secretion (containing many enzymes for enzyme-secreting glands)
parotid gland
vasoconstriction and slight secretion —— stimulation of copious secretion (containing many enzymes for enzyme-secreting glands)
submandibular gland
vasoconstriction and slight secretion —— stimulation of copious secretion (containing many enzymes for enzyme-secreting glands)
gastric gland
vasoconstriction and slight secretion —— stimulation of copious secretion (containing many enzymes for enzyme-secreting glands)
pancreatic gland
vasoconstriction and slight secretion —— stimulation of copious secretion (containing many enzymes for enzyme-secreting glands)
sweat glands
copious sweating (cholinergic) ——– sweating on palms of hands
apocrine glands
thick, odoriferous secretion ——- none
blood vessels
most often constricted —– most often little or no effect
heart muscle
increased rate/force of contraction —- slowed rate/decreased force of contractility (especially atria)
Coronaries
Dilated (beta2); constricted (alpha1) —– dilated
bronchi
dilated —- constricted
blood vessels (lungs)
mildly constricted — ? dilated
