Sciatic nerve Sciatic nerve The sciatic nerve (also called "ischiadic nerve", "ischiatic nerve") is a large nerve in humans and other animals. It begins in the lower back and runs through the buttock and down the lower limb. It is the longest and widest single nerve in the human body, going from the top of the leg to the foot on the posterior aspect. The sciatic nerve provides the connection to the nervous system for nearly the whole of the skin of the leg, the muscles of the back of the thigh, and those of the leg and foot. It is derived
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
