Tibial nerve

The tibial nerve branches off the sciatic nerve. It provides instructions to the muscles in the lower leg and foot. In addition, the sural nerve branches off it, which provides sensation in the skin of the legs and feet. The tibial nerve generally follows the tibial artery through the body, which supplies blood to the same areas. Damage to the tibial nerve results in a condition known as tibial nerve dysfunction. This is characterized by a loss of feeling or movement in the lower leg. While this may be caused by a variety of conditions, including systemic diseases such as diabetes, it is more commonly experienced by those who have fractured their tibias. There are two major branches of the tibial nerve in the foot: the medial plantar nerve and the lateral plantar nerve. The former supplies instructions to the big toe and the two toes next to it, and the latter the other two toes. The split is seen just after the heel.
