Autonomic Nerve Blocks
There are two nervous systems
somatic nervous system - normal motor and sensory nerves that most people are familiar with. It is organized like a centralized federal government, with the brain and spinal cord in charge.
autonomic nervous system - another very extensive system that controls blood flow, sweating and many other secretions, digestion, heart beat and other organ functions. It also has significant influence on pain. It is then divided into two parts.
- The parasympathetic nervous system is the autonomic nerves that help us relax, secrete and digest.
- The sympathetic nervous system is the autonomic nerves that stop secretion and peripheral blood flow in response to fight or flight situations, or perhaps just greater situational stresses.
