Sciatic nerve behind (superficial to) the adductor magnus muscle, and is itself in front of (deep to) one head of the biceps femoris muscle. At the popliteal fossa, the nerve divides into its two branches: The sciatic nerve is the largest nerve in the human body. The sciatic nerve supplies sensation to the skin of the foot, as well as the entire lower leg (except for its inner side). Sensation to skin to the sole of the foot is provided by the tibial nerve, and the lower leg and upper surface of the foot via the common fibular nerve. The sciatic nerve
Hypogastric nerve Hypogastric nerve The hypogastric nerve is the nerve that transitions between the superior hypogastric plexus and the inferior hypogastric plexus. The hypogastric nerve enters the sympathetic chain at T10-L2. The hypogastric nerve begins where the superior hypogastric plexus splits into a right and left plexus. Each of these divisions is considered a hypogastric nerve. The hypogastric nerve continues inferiorly on its corresponding side of the body, where it descends into the pelvis to form the inferior hypogastric plexus. Contents of the right and left hypogastric nerves include pre- and post-ganglionic sympathetic fibers from vertebral levels of T10-L2. The hypogastric nerve
