Q
what does the sympathetic system affect ?
A
dilates bronchioles. increases heart action, increases skeletal muscle blood flow, dilates pupils, stimulates glycogenolysis in liver
2
Q
more sympathetic actions
A
raised metabolic rate, liopolysis, and alertness by stimulating the reticular formation
3
Q
parasympathetic actions
A
constricts pupils, decreases HR, constricts bronchioles
- stimulates GI secretion and contraction to increase digestion
