Andersch's ganglions nerve, also known as the calcaneal branch of the tibial nerve or the medial calcaneal nerve, is a peripheral sensory nerve located in the foot. It is part of the complex network of nerves in the lower extremities responsible for providing innervation to the skin, muscles, and other structures in the foot.
Specifically, Andersch's ganglions nerve arises from the tibial nerve, which is one of the two main branches of the sciatic nerve in the leg. It emerges as a small sensory branch about halfway down the leg and descends through the medial aspect of the leg before reaching the medial side of the heel. At this point, it divides into multiple branches that supply sensory innervation to the skin on the sole and plantar aspect of the heel, as well as surrounding tissue.
The function of Andersch's ganglions nerve is to transmit sensory information from the heel region to the brain. This includes sensations of touch, pressure, pain, and temperature perception in the heel. Dysfunction or damage to this nerve can result in various symptoms, such as numbness, tingling, or pain in the heel area, which may affect one's ability to stand, walk, or bear weight on the affected foot.
Overall, Andersch's ganglions nerve plays a crucial role in providing sensory innervation to the heel region, contributing to the overall functioning and sensation of the foot.
