Sciatic Nerve and Sciatica
http://TheBackPainInstitute.org In 10 days we are doing a series of articles and videos on sciatic nerve pain or sciatica. We'll focus on what is called the back pain complex, primarily sciatica pain.
The sciatic nerve is the longest and largest energize in the body measuring three-lodging of an inch in diameter. The ischiadic nerve originates in the sacral plexus; a reticulated of nerves in the low back (lumbosacral ridge).
The lumbosacral spine refers to the lumbar thorn and the sacrum combined. The ischiatic nerve and its nerve branches qualify movement and feeling (motor and sensory functions) in the thigh, knee, calf, ankle, pay, and toes. The sciatic nerve and the lumbosacral vertebral column is pictured below.
Sciatic Symptoms
If the sciatic nerve is injured or becomes inflamed, it causes symptoms called hip-gout. Sciatica can cause intense pain at the same time any part of the sciatica strengthen pathway - from the buttocks to the toes. If the power is compressed, caused by conditions in the same state as a bulging or herniated disc or tumor (rare), symptoms may include a deprivation of reflexes, weakness and numbness also severe pain.
Sciatic nerve pain have power to make everyday activities such as walking, session and standing difficult.

How Sciatica Pain Can Spread
The of the hip nerve exits the sacrum (pelvic yard) through a nerve passageway called the sciatic foramen. At the upper part of the ischiatic nerve, two branches form; the articular and sturdy branches. The articular branch supplies the hip joint.
The muscular branch serves the leg flexor muscles; muscles that qualify movement.
The sciatic nerve also enables motion (motor function) and feeling (sensory office) to the thigh, knee, calf, ankle, bottom and toes. Other complex nerve structures are involved; the peroneal nerves and tibial nerves. The peroneal nerves give rise to from the nerve roots at the fourth and fifth lumbar thorn (L4-5) and first and maintainer levels of the sacrum (S1-2).
After the peroneal nerves farewell the pelvis, they travel down the meet face to face and side of the leg, and at the same time the outer side of the knee, to the discharge. The tibial nerves originate from the fortify roots at L4-5 and S1-3. The tibial nerves die in front of the knee and in a descending course into the foot (heel, sole, toes).
