Superficial Fibular

The superficial fibular nerve is a terminal branch of the common fibular nerve, which itself is a branch of the sciatic nerve. The superficial fibular nerve contains both motor and sensory fibers, meaning it provides both motion and sensation. The superficial fibular nerve arises from the common fibular nerve below the head of the fibula. It travels down the lateral side of the leg, superficial to the peroneus longus and brevis muscles. It then pierces the deep fascia of the leg and becomes subcutaneous. It continues down the lateral side of the leg, supplying sensation to the skin over the anterolateral aspect of the leg and the dorsum of the foot (with the exception of the first web space, which is innervated by the deep fibular nerve). It also supplies motor innervation to the peroneus longus and brevis muscles. The superficial fibular nerve is susceptible to injury due to its superficial location. Injury to the superficial fibular nerve can cause numbness, tingling, and weakness in the muscles of the lateral leg and foot. In some cases, it can also cause foot drop, which is a condition in which the foot cannot be lifted off the ground. The superficial fibular nerve is a very important nerve, and damage to it can be debilitating. If you experience any symptoms of superficial fibular nerve injury, it is important to see a doctor to determine the cause and to discuss treatment options. Here are some additional facts about the superficial fibular nerve: It is the largest terminal branch of the common fibular nerve. It supplies sensation to the skin over the anterolateral aspect of the leg and the dorsum of the foot (with the exception of the first web space). It supplies motor innervation to the peroneus longus and brevis muscles. It is susceptible to injury due to its superficial location. Injury to the superficial fibular nerve can cause numbness, tingling, and weakness in the muscles of the lateral leg and foot. In some cases, it can also cause foot drop.

Sciatic

Ventral rami of l4-s3 with parts of l4 and s4 spinal nerves form the sacral plexus. it is located on the posterior wall of pelvic cavity (pelvis minor). nervi of the plexus innervate the perineal region, buttocks and the lower limb. the largest nerve of the human body, the sciatic nerve, is the main branch that gives rami to the motor innervation of the muscles of the thigh, the leg, and the foot. common peroneal nerve and its branches innervate some parts of the skin of the foot, the peroneal muscles of the leg, and the dorsal muscles of the foot.
