Clinical InformationClinical
Sciatic Nerve
a nerve which originates in the lumbar and sacral spinal cord (l4 to s3) and supplies motor and sensory innervation to the lower extremity. the sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. it has two major branches, the tibial nerve and the peroneal nerve.Sciatic Neuropathy
disease or damage involving the sciatic nerve, which divides into the peroneal nerve and tibial nerve (see also peroneal neuropathies and tibial neuropathy). clinical manifestations may include sciatica or pain localized to the hip, paresis or paralysis of posterior thigh muscles and muscles innervated by the peroneal and tibial nerves, and sensory loss involving the lateral and posterior thigh, posterior and lateral leg, and sole of the foot. the sciatic nerve may be affected by trauma; ischemia; collagen diseases; and other conditions.

Autonomic Nervous System Disorders
Your autonomic nervous system is the part of your nervous system that controls involuntary actions, such as the beating of your heart and the widening or narrowing of your blood vessels. When something goes wrong in this system, it can cause serious problems, including:

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
