Simple basics - Peripheral Nervous System 101

Peripheral Nervous System (PNS) 101

Unlike the CNS, the PNS is not protected by the bone of spine and skull, or by the blood-brain-barrier, leaving it exposed to toxins and mechanical injuries

The PNS is comprised of nerves (neurons) that are either MOTOR or SENSORY

Which one is determined by direction of nerve impulses:

(i) Sensory/afferent neurons.   Relay nerve impulses toward the central nervous system (CNS).   E.g. A touch or painful stimulus creates a sensation in the brain after information about the stimulus travels through the spinal cord to the brain via afferent nerve pathways.

(ii) Motor /efferent neurons.   Relay nerve impulses away from the CNS

CNS  to Peripheral nervous system neuron connections

Communication between CNS and PNS

PNS nerves are used for control of SOMATIC (Conscious/voluntary) or AUTONOMIC (Subconscious/involuntary) functions

(i) SOMATIC nervous system (SNS) (Conscious/voluntary control)

Includes all of the nerves that serve the skeletal muscles and the exterior sense organs, and also includes reflexes.   Connects skeletal muscles with cells specialized to respond to sensations, such as touch and pain.

(ii) AUTONOMIC nervous system (ANS)  (Generally subconscious control)

 Motor and sensory neurons connecting the CNS with internal organs (E.g. heart), smooth muscle, glands.

•  SYMPATHETIC nervous system.   Mobilizes energy and resources during times of stress and arousal

•  PARASYMPATHETIC nervous system.    Conserves energy and resources during relaxed states.

•  ENTERIC nervous system.   Neurons directly control the digestive tract, pancreas, and gallbladder.

The PNS in humans comprises:

12 pairs of cranial nerves.   Emerge directly from the brain, sensory nerves, motor nerves, or mixed nerves. All of them control the head, face, neck, and shoulders, except the vagus nerve, which controls the internal organs.

31 pairs of spinal nerves.   Emerge from segments of the spinal cord; mixed nerves that take impulses to and from the spinal cord.

The Body Electric

General electrotherapy health benefits.   Used systemically and/or locally at specific problem areas of the body, its effective application has many benefits:

Detoxification Wellness / Healthy aging Pain relief 
Relief from insomnia Immune system restoral Anti-Inflammatory
Maximizes cellular energy production Accelerated tissue /bone
/scar healing
Stress Reduction
Muscle relaxation / rehabilitation Increased blood oxygen
/ circulation

There are several reasonably affordable electrotherapy devices available for personal use. The following electrotherapies are those that have received a significant amount of positive feedback:

Cranial Electrotherapy Stimulation (CES) applies specific frequency patterns to the head area, with the following benefits:

Balances neurotransmitters Relieves pain Treats depression
Substance abuse withdrawal Relieves insomnia Relieve stress / anxiety
Anti-Inflammatory Fibromyalgia +++
