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.
The fibularis brevis is the strongest abductor of the foot. [2] Together with the fibularis longus and the tibialis posterior, it extends the foot downward away from the body at the ankle (plantar flexion). It opposes the tibialis anterior and the fibularis tertius, which pull the foot upward toward the body (dorsiflexion). [3]
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 fibularis longus, together with the fibularis brevis and the tibialis posterior, extend the foot downward away from the body at the ankle (plantar flexion). It opposes the tibialis anterior and the fibularis tertius , which pull the foot upward toward the body ( dorsiflexion ).
The muscle passes under the superior and inferior extensor retinaculum of foot in company with the fibularis tertius, and divides into four slips, which run forward on the dorsum of the foot, and are inserted into the second and third phalanges of the four lesser toes.
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 ...
