Peroneus longus Definition. It is the more superficial of the two lateral muscles of the lower leg. The long, strap-like structure is also called fibularis longus. The term Peroneus is derived from a Greek word called âPeroneâ referring to pin of a buckle.Simply put, it relates to the fibula of the leg.eroneus longus Anatomy. The lateral muscle of the leg is interspersed by fibers from the lateral condyle of the tibia. The common fibular nerve passes to the exterior portion of the leg through a gap in order to innervate the muscle.
âThere are two peroneal tendons that run along the back of the fibula (Figures 1 and 2). The first is called the peroneus brevis. The term brevis implies short. It is called this because it has a shorter muscle and starts lower in the leg. It then runs down around the back of the bone called the fibula on the outside of the leg and inserts (i.e. connects) to the fifth metatarsal. This is in the side of the foot. The peroneus longus takes its name because it has a longer course.
