Deep Fibular

The deep fibular nerve is a branch of the common fibular nerve that supplies motor innervation to the muscles in the anterior compartment of the leg and sensory innervation to the skin on the dorsum of the foot. It arises from the common fibular nerve in the popliteal fossa and descends through the anterior compartment of the leg, between the tibialis anterior and extensor digitorum longus muscles. It then pierces the interosseous membrane and continues down the leg, between the extensor muscles of the foot.

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.
