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
Supratrochlear nerve It then divides into branches which pierce these muscles and supplies the following areas: "Supratrochlear" means "above the trochlea". The term "trochlea" means "pulley" in Latin. Specifically, the trochlea referred to is a loop inside the orbit of the eye, through which the tendon of the superior oblique muscle passes. Supratrochlear nerve In human cranial neuroanatomy, the supratrochlear nerve is a branch of the frontal nerve, which itself comes from the ophthalmic division of the trigeminal (or fifth) cranial nerve. It is smaller than the nearby supraorbital nerve. It passes above the pulley of the superior oblique muscle, and gives
