The fibularis tertius is supplied by the deep fibular nerve. [ 2 ] [ 3 ] In rare cases, it may also be supplied by the common fibular nerve . [ 2 ] This is unlike the other fibularis muscles , which are located in the lateral compartment of the leg and are supplied by the superficial fibular nerve , since the fibularis tertius is found in the ...
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 ...
The anterior compartment of the leg is a fascial compartment of the lower leg.It contains muscles that produce dorsiflexion and participate in inversion and eversion of the foot, as well as vascular and nervous elements, including the anterior tibial artery and veins and the deep fibular nerve.
Peroneus tertius; Deep fibular (peroneal) nerve and anterior tibial vessels: Lateral compartment: Fibularis longus; Fibularis brevis; Superficial fibular (peroneal) nerve and fibular artery: Deep posterior compartment: Tibialis posterior; Flexor hallucis longus; Flexor digitorum longus; Popliteus
The superficial fibular nerve (also known as superficial peroneal nerve) is a mixed (motor and sensory) nerve that provides motor innervation to the fibularis longus and fibularis brevis muscles, and sensory innervation to skin over the antero-lateral aspect of the leg along with the greater part of the dorsum of the foot (with the exception of the first web space, which is innervated by the ...
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 ...
The superior extensor retinaculum binds down the tendons of extensor digitorum longus, extensor hallucis longus, peroneus tertius, and tibialis anterior as they descend on the front of the tibia and fibula; under it are found also the anterior tibial vessels and deep peroneal nerve. [1]
Main Action 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 ...
