Arches of the foot Arches of the foot. The arches of the foot, formed by the tarsal and metatarsal bones, strengthened by ligaments and tendons, allow the foot to support the weight of the body in the erect posture with the least weight. They are categorized as longitudinal and transverse arches.

Muscles, Tendons & Ligaments of the Foot & Ankle There are elastic tissues (tendons) in the foot that connect the muscles to the bones and joints. The largest and strongest tendon of the foot is the Achilles tendon, which extends from the calf muscle to the heel. Its strength and joint function facilitate running, jumping, walking up stairs, and raising the body onto the toes. Ligaments hold the tendons in place and stabilize the joints. The longest of these, the plantar fascia, forms the arch on the sole of the foot from the heel to the toes. By stretching and contracting, it allows the arch to curve or flatten, providing balance and giving the foot strength to initiate the act of walking.

Gastrocnemius Muscle (Medial Head) Gastrocnemius Muscle (Medial Head) The gastrocnemius muscle is the most superficial and prominent of the calf muscles. It is made of two muscular regions, the medial head and lateral head, which attach to the medial and lateral sides of the femur. The heads of the gastrocnemius muscle work together to plantarflex the foot at the ankle and to flex the leg at the knee. Anatomy.

THE LOWER EXTREMITY The calf muscles. The gastrocnemius, soleus and plantaris muscles are known as the calf muscles. They form the superficial muscles of the posterior compartment of the leg. The deep muscles of the posterior compartment of the leg are the popliteus, tibialis posterior, flexor digitorum longus and flexor hallucis longus.The gastrocnemius calf muscle is the most superficial of the calf muscles. It inserts onto the heel bone via the Achilles tendon.The gastrocnemius muscle flexes the foot at the ankle joint — that is it acts to point the foot downwards by bending it at the ankle joint, such as when you stand on your toes.eg (knee to ankle) - superficial posterior view. View the surface muscles of the leg from the back. See where the soleus and gastrocnemius muscles — commonly known as the calf muscles — are. The calf muscles are essential to pushing off from the ground and standing on your toes.

Plantar fascia The plantar fascia is the thick connective tissue (aponeurosis) which supports the arch on the bottom (plantar side) of the foot.It runs from the tuberosity of the calcaneus (heel bone) forward to the heads of the metatarsal bones (the bone between each toe and the bones of the mid foot).he plantar fascia is a broad structure that spans between the medial calcaneal tubercle and the proximal phalanges of the toes. Recent studies suggest that the plantar fascia is actually an aponeurosis rather than true fascia.

Peroneal Tendon Problems So the ankle bump on the inside edge of the ankle (closest to your other ankle) is the medial malleolus. The term lateral refers to structures furthest from the center. Major muscles that support the lateral part of the ankle are the peroneus longus and the peroneus brevis.

Plantaris injury Anatomy. The plantaris muscle is a fine rope like tendon running next to the larger Achilles Tendon. It’s function is to work with the Achilles to flex the ankle and knee joint by extending from the outside (lateral) back of the femur (allowing you to stand on your toes or point your foot).nless associated with bony injury, x-rays of the area will not be useful. Injury to the plantaris muscle can present with similar clinical features to conditions like deep vein thrombosis, rupture of Baker's cyst, and tumors. An MRI is accurate in differentiating and characterizing plantaris muscle injury.

- Beneath it lies the soleus muscle (Image 1C), which holds the real strength and power in the calf. These two muscles help you to stand, walk, run, and rise up on the balls of your feet. Both are attached to the back of the calcaneous by the Achilles tendon (Image 1D).

These muscles are sometimes referred to as fibularis longus and brevis due to their attchments on the fibula. Origin : Head of fibula. Upper 2/3 of fibula.

Muscles, Tendons & Ligaments of the Foot & Ankle The main muscles of the foot are: 1  the anterior tibial, which enables the foot to move upward; 2  the posterior tibial, which supports the arch; 3  the peroneal tibial, which controls movement on the outside of the ankle; 4  the extensors, which help the ankle raise the toes to initiate the act of stepping forward; and.

Peroneus Brevis The peroneal tendons are two strong tendons that connect the muscles on the outside of the leg to the bones in the foot. They run behind the bone in the ankle called the fibula. When they contract they move the foot down and out. They play an important role in stabilizing the foot on uneven surfaces.

Plantar Fascia Strain Plantar Fascia Strain. The plantar fascia or arch ligament is a band that runs from under the heel to the front of the foot. A strain or rupture to this is quite common. A plantar fascia strain might result from one single traumatic incident or may gradually occur over a period of time.

- A: The peroneus longus, the gastrocnemius and the soleus muscles are involved in plantar flexion. The muscles work together to allow a body to stand up on its toes. The peroneus longus muscle is also referred to as the fibularis longus because it is the longest muscle attached to the fibula. Continue Reading

Anatomy Anatomy The posterior tibial tendon is one of the most important tendons of the leg. A tendon attaches muscles to bones, and the posterior tibial tendon attaches the calf muscle to the bones on the inside of the foot. The main function of the tendon is to hold up the arch and support the foot when walking.
