Effects of sympathetic/parasymp on ANS

Sweat

para- no known effect

sym- increase sweating (muscarinic receptors)

Lacrimal

para- tears

sym- no known effect

salivary

para- large volume of watery saliva

sym- small volume of thick, viscous saliva

pancreas

para- secretion of digestive enzyme and insulin

sym- inhibit digestive enzyme/insulin secretion (alpha) promate glucagon secretion (beta)

gastric

para- secretion of gastric juice

sym- inhibit secretion of gastric juice

intestinal

para- secretion of intestinal juice

sym- inhibit secretion

adrenal medulla

para- no known

sym- secretion of epi/norepi (nicotinic)

Liver

para- glycogen synthesis, ^ bile secretion

sym- glycogenolysis, gluconeogenesis, and decreased bile

adipose tissue

para- no known

sym- lipolysis and release of fatty acids

kidneys

para- no known

sym- renin secretion

Most receptors for parasympathetic/sympathetic stimulation in ANS

para- muscarinic ACh

sym- Adrenergic receptors

Cardaic muscle

para- decreased heart rate and decreased action potential to rest of heart

sym- increased heart rate, increased action potential to heart

Coronary arteroiles

para- contraction → vasoconstriction

sym- relaxation → vasodilation

Skin arteroiles

para- vasodilation

sym- contraction → vasoconstriction

Skeletal muscle arterioles

para- no known

sym- relaxation → vasodilation

abdominal viscera arterioles

para- no known

sym- contraction → vasoconstriction

Kidney (arterioles)

para- no known

sym- vasoconstriction → decreased urine volume

Systemic veins

para- no known

sym- contraction → constriction; relaxation → dilation

Iris, circular smooth muscles

para- contraction → constriction of pupil

sym- no known effector

Iris, radial smooth muscle

para- no known 

sym- contraction → dilation of pupil

Ciliary muscle of eye

para- contraction for near vision

sym- relaxation of far vision

lungs, bronchial muscle

para- contraction → airway constriction

sym- relaxation → airway dilation

stomach and intestine

para- increase motility and tone

sym- decreased motility and tone

Gallbladder and duct

para- contraction → release of bile into SI

sym- relaxation to facilitate bile storage

Spleen

para- no known effect

sym- contraction/discharge of stored blood into general circulation

urinary bladder

para- contraction of muscular wall

sym- relaxation of muscular wall

sex organs

para- vasodilation, erection

sym- ejaculation in males

hair follicles

para- no known

sym- contraction → erection causing goosebumps
