Plantar peroneus nerve Nervus peroneus profundus (or more commonly known as the great toe nerve) is one of the three major nerves of the human lower extremity, providing innervation and blood supply to the lower leg, in addition, it is the largest branch of the sciatic nerve.
The original name of the plantar peroneal nerve is the lateral plantar nerve, and the nerve itself is epiphytic. The name of the nerve is derived from the Greek word “epiphysis” - joint, place of attachment to the foot. The Latin term "peroneus" literally means "coming from the foot", with "superficialis" being translated as "superficial". This nerve rightfully bears this name only because it leaves the spine to the shin bone and is adjacent to the skin. It serves as the main source of innervation of the foot and back of the leg. There are only three branches: anterior, middle and posterior. Also, its presenting branches make it possible to supplement the interosseous membrane of the femur with connective tissue, which blocks the bony septa, providing a strong connection between adjacent bones. It also has important functions in shaping the shape of the muscles of the lower leg, thigh and arch of the ankle.
This major trunk nerve enters the terminal branch of the ischial bones (anterior branch) and supplies the following functions: - A large group of muscles, including the posterior group of gastrocnemius muscles, and the talofibular muscles; - Bone involved in the formation of the leg bones;
**Anatomical features**. Represented by one round nerve - anterior and posterior. Has a wide
