The fibularis longus also tilts the sole of the foot away from the midline of the body . Because of the angle at which it crosses the sole of the foot, it plays an important role in maintaining the transverse arch of the foot. [2] Together, the fibularis muscles help to steady the leg upon the foot, especially in standing on one leg. [2]

The fibular retinacula (also known as peroneal retinacula) are fibrous retaining bands that bind down the tendons of the fibularis longus and fibularis brevis muscles as they run across the side of the ankle. (Retinaculum is Latin for "retainer.") These bands consist of the superior fibular retinaculum and the inferior fibular retinaculum.
The fibularis tertius is located in the anterior compartment of the leg and is supplied by the anterior tibial artery and the deep fibular nerve. While all three muscles move the sole of the foot outward, away from the midline of the body ( eversion ), the longus and brevis extend the foot downward away from the body ( plantar flexion ...
Fibularis longus: Head and superior two thirds of lateral surface of fibula: Base of 1st metatarsal and medial cuneiform: Superficial fibular nerve (L5, S1, S2) Everts foot and weakly plantarflexes ankle Fibularis brevis: Inferior two thirds of lateral surface of fibula: Dorsal surface of tuberosity on lateral side of base of 5th metatarsal
Extensor digitorum longus: Lateral condyle of tibia and superior three quarters of medial surface of fibula and interosseous membrane: Middle and distal phalanges of lateral four digits: Extends lateral four digits and dorsiflexes ankle Fibularis tertius: Inferior third of anterior surface of fibula and interosseous membrane: Dorsum of base of ...
The fibularis (peroneus) longus and fibularis (peroneus) brevis both have their origins on the fibula, and they both pass behind the lateral malleolus where their tendons pass under the fibular retinacula. Under the foot, the fibularis longus stretches from the lateral to the medial side in a groove, thus bracing the transverse arch of the foot ...
