Together, they regulate the involuntary and reflexive functions of the human body. The parasympathetic nervous system, or PSNS, is part of the nervous system. The parasympathetic nervous system is our natural restoring system and manages the body's rest, digest, growth and repair processes. The parasympathetic nervous system assists with the body's "rest and digestion" after the "flight and fight" response. The PSNS gives the body a calm and relaxed feeling over a period of time.

The parasympathetic nervous system is characterized by peripheral ganglia from BIO 2121 at Clark State Community College. The parasympathetic nervous system consists of many pathways that connect its craniosacral components with the peripheral tissues. Each parasympathetic pathway consists of two neurons, the presynaptic (preganglionic) and postsynaptic (postganglionic) neurons, which are connected by the axons of the presynaptic neurons.

The parasympathetic division of the autonomic nervous system is named because its central neurons are located on either side of the thoracolumbar region of the spinal cord (para- = "beside" or "near"). In modern lifestyles and experiences, there is a tendency and societal push for production that can overshadow the need for restoration and create an energetic imbalance.
