Autonomic Nervous System (ANS)

Outline of the Functions of Parasympathetic and Sympathetic Divisions of the ANS

Table 16-10-1: The ANS controls internal glands + muscles beyond conscious control
Target Organ/Tissue Parasympathetic Stimulation Sympathetic Stimulation
Iris of eyes Constricts pupil Dilates pupil
Bronchi, bronchioles Constricts tubes Dilates tubes
Blood vessels - Dilates blood vessel - Lowers blood pressure - Constricts blood vessels - Raises blood pressure
Heart - Lowers heart rate - Lowers stroke volume - Raises heart rate - Raises stroke volume
Intercostal muscles Lowers breathing rate Raises breathing rate
Salivary glands Stimulates secretion of salvia Inhibits secretion of salvia
Gut Stimulates peristalsis Inhibits peristalsis
Sweat glands No effect Increases sweat production
