epinephrine (or adrenaline in the UK) mimics the effects of norepinephrine (noradrenaline in UK), so activates the SNS, not the PSNS.
The sympathetic and parasympathetic nervous systems are subdivisions of the autonomic nervous system.

The Sympathetic Nervous System and the Parasympathetic Nervous System
Unless some other factor (e.g., a bear trying to attack you) activates your sympathetic nervous system, the parasympathetic, not the sympathetic, nervous system is active after eating. Parasympathetic activation results in a decline of the stress hormones epinephrine and norepinephrine, which allows blood to be directed towards the digestive system so that digestion and absorption of nutrients can occur. When the sympathetic nervous system is activated, blood is diverted from the "non-essential" organs, such as the digestive system, and towards the heart, brain, and muscles.
The autonomic nervous system is divided into the sympathetic and parasympathetic systems.
