Information from body and external environment (Low, 2018).

Autonomic nervous system receives information (Low, 2018). Controls the unconscious function of the smooth muscles of the internal organs (Papathanasiou & Coppens, 2017).

Sympathetic division stimulates body processes (Low, 2018).

Parasympathetic division inhibits body processes (Low, 2018).
