    UNDERSTANDING SCIATICA: DOES PHYSICAL THERAPY HELP?

    ANATOMY OF THE SCIATIC NERVE
    Sciatica and or herniated disc (HNP) are two common diagnosis that are responsible for back pain at any age. The sciatic nerve is the largest and longest nerve in the human body. During examination in gross anatomy lab it appeared to look like a very thick semi opaque fiber optic cable. It can measure up to three quarters of an inch in diameter and consists of a bundle of five nerves that branch from the lower portion of the spinal cord. At knee level the sciatic nerve splits into the tibial and common fibular nerves and controls the lower leg and foot. Within this bundle are fibers that allow us to feel sensation in the skin surrounding the hip and thigh and motor fibers that conduct movement in the hip, leg and foot.
