Autonomic Nerve Chart


The Autonomic Nerve Chart 11″ x 17″ laminated By Dr. Bernard Jensen


The Autonomic Nerve Chart shows each of the spinal vertebrae, pictured and numbered from C1 to S4. Lines representing nerves are shown, connecting each vertebra to the corresponding body parts. A clear division is made in the autonomic nervous system between the sympathetic and parasympathetic systems.

What is The autonomic nervous system (ANS) 

The autonomic nervous system (ANS) is a division of the peripheral nervous system that controls involuntary bodily functions, including heart rate, digestion, respiratory rate, pupillary response, and other processes. It operates unconsciously and regulates the internal organs to maintain homeostasis and respond to stress.

The autonomic nervous system is divided into two main branches:

  1. Sympathetic Nervous System (SNS): Often referred to as the “fight or flight” system, the sympathetic nervous system is activated in response to stress or danger. It prepares the body for a quick reaction by increasing heart rate and dilating pupils. Redirecting blood flow to muscles and inhibiting non-essential functions like digestion can also result.
  2. Parasympathetic Nervous System (PNS): Often called the “rest and digest” system, the parasympathetic nervous system is activated during periods of relaxation. It slows down heart rate, constricts pupils, promotes digestion, and conserves energy.

On the other hand, the PNS is commonly known as the “rest and digest” system. It operates during periods of relaxation and recovery, countering the effects of the SNS. The PNS slows down heart rate, promotes digestion, and conserves energy, allowing the body to recover and restore equilibrium after a stressor has passed.

The delicate interplay between these two branches is crucial for overall well-being. An imbalance in the autonomic nervous system can lead to various health issues, including cardiovascular problems, gastrointestinal disorders, and disturbances in sleep patterns.

Moreover, the autonomic nervous system is not limited to the cardiovascular and digestive systems. It also plays a vital role in regulating respiratory function, pupillary responses, and glandular activities. The autonomic nerves, composed of intricate networks of neurons, transmit signals from the central nervous system to various organs and tissues, coordinating a harmonious response to internal and external changes.

The Autonomic Nerve Chart will assist you in Understanding the autonomic nervous system, which is essential for comprehending how the body adapts to different situations and environments, highlighting its intricate role in maintaining physiological stability and responding appropriately to the myriad challenges of daily life.
