In human anatomy the peroneus longus also known as fibularis longus is a superficial muscle in the lateral compartment of the leg and acts to evert and plantarflex the ankle. It becomes a tendon that goes posteriorly around the lateral malleolus of the ankle then continues under the foot to attach to the 1st metatarsal. Extensor digitorum longus extensor hallucis longus and tibialis anterior.

Head and proximal 12 to 23 of lateral side of fibula. Injury to the peroneus longus can cause pain decreased motion and difficulty. Tendon wraps under foot to base of 1st metatarsal and 1st cuneiform.

It starts at the top of the fibula before running down the. The lateral head and the upper 23 of the lateral surface of the fibula and the anterior and posterior intermuscular septa of the leg. The Peroneal Longus extends down the lateral compartment of the lower limb where at the midpoint it tapers in to a long tendon that descends in to the foot.

Lower 23 lateral fibular shaft. Reversed origin insertion action. Fibularis tertius muscle also called peroneus tertius is located on the lower lateral aspect of the leg.

Insertion From its origin the peroneus longus passes downward behind the lateral malleolus and inserts onto the medial cuneiform and the first metatarsal bone. From the head and upper two thirds of the peroneal aspect of the shaft of the fibula and intermuscular septum. Crosses plantar surface of foot to attach to lateral sides of medial 1st cuneiform and 1st metatarsal.

Soleus muscle stabilizes the tibia on the calcaneus limiting forward sway. Upper 23 of fibula. The insertional points presence of sesamoid bone and variations in.

The peroneus longus fibularis longus is a superficial muscle in the lateral compartment of the leg muscles and works to evert and plantarflex the ankle joint. Need help learning the muscles of the leg. The muscle is considered an extrinsic ankle muscle.

Origin Insertion Action Nerve Supply. Collectively they are responsible for ankle dorsiflexion. The Peroneus brevis muscle origin and insertion.

The peroneus longus tendons are held in place near your lateral ankle by the superior peroneal retinaculum a thick band of tissue. Plantar flexion pronation arch support. Peroneus longus is a superficial muscle that can easily be seen and palpated.

Insertion the peroneal longus tendon passes down the leg superficial to the peroneus brevis muscle and does not touch the lateral malleolus due to the intervening brevis tendon. It originates in your leg and attaches to your foot and serves to move your ankle. Peroneus Longus Peroneus Longus is one of the peroneal muscle groups which passes down the outside of the lower leg and everts turn out the foot.

These muscles are sometimes referred to as fibularis longus and brevis due to their attachments on the fibula.
