Blows to Nerves
The external tissues surrounding a nerve may be bruised from blunt trauma casing pressure on the nerve causing temporary paralysis. If the myelin sheath that covers a nerve is cut, then the nerve takes longer to heal, If a nerve is separated, it may cause permanent paralysis.
Brachial Plexus Nerve
Comes out of the neck near the spinal cord slightly above the shoulders, goes under the collar bone (clavicle), through the armpit, and down the arm. It may be struck with a blow directed at the base of the neck at the shoulders, by breaking the clavicle, or by striking inward and upward into the armpit.
Located at the base of the skull where it connects to the spine, it is one of the most vital areas. It may be struck with any type of blow to the base of the skull.
One of the largest nerves in the body. It emerges from the rump and extends down the center of the backside of each leg, one to two inches below the skin. It controls the lifting and placement of the foot. It has no protection except for the overlying muscles.
Thoracic Section of the Spinal Cord
The lower section of the spinal cord. Next to the neck, it is the weakest area of the spine.
Blow to any of the vital points of the head may cause trauma to the cranial nerves resulting in loss of nervous coordination and consciousness as well as vascular shock. Eleven cranial nerves possess sensory, motor, or mixed functions:
- Vagus Spinal Accessorius
Striking a nerve, such as the common peroneal nerve in the upper leg causes pain called a “charlie horse” and causes a motor dysfunction. A motor dysfunction occurs when a strike over-stimulates motor nerves resulting in a temporary muscle impairment. By creating a motor dysfunction by striking muscle mass only, the potential for subject injury is reduced to bruises. Tactically, creating a motor-dysfunction is a more reliable technique than striking a joint. A motor dysfunction is a neural-muscular response and is not dependent upon the subject’s tolerance for pain. In contrast, incapacitating a subject by attempting structural damage is unpredictable in effectiveness.
There are instances where athletes have played with damaged joints or broken bones. A motor dysfunction is strictly a neural/muscular response that is not influenced by the person’s ability to feel pain although the person may feel pain later. Tests have shown that motor dysfunction’s are usually accompanied with a high level stun on people that are both sober or under the influence of alcohol. For people that are under the influence of a chemical stimulant, the motor dysfunction does occur but the person rarely feels any type of pain. The average motor dysfunction may last from 30 seconds up to several minutes but it could last much longer. Most of the time, there is also a sympathetic reflex response which is a flexing of the unaffected area. Thus the assailant becomes incapacitated and self-defense/control is accomplished.
