The reticular activating system (RAS) is a network of neurons that runs through the core of the hind‐brain and into the midbrain and forebrain. PNS effects include increased stomach activity and decreased blood flow to the muscles. Conversely, the PNS functions when the body is relaxed or at rest and helps the body store energy for future use. Activation of the SNS causes the production of epinephrine (adrenaline) from the adrenal glands, increased blood flow to the muscles, increased heart rate, and other readiness reactions. When activated, the SNS prepares the body for emergency actions it controls glands of the neuroendocrine system (thyroid, pituitary, and adrenal glands). The autonomic nervous system (ANS) has two components, the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). Theorists differ on the order of appearance of the reaction patterns.
