This is a table of neurotransmitter actions in the ANS (autonomic nervous system). It includes the circulatory system, the respiratory system, the visual system, the digestive system, the endocrine system, the urinary system, the reproductive system, and the integumentary system. Both effects of the sympathetic nervous system (adrenergic) and parasympathetic nervous system (muscarinic) are included.
<sup>â±</sup> The bronchioles have no sympathetic innervation, but are instead affected by circulating adrenaline
