Soleol line4/24/2023 ![]() The soleus’ function is closely related to that of the gastrocnemius muscle. Learn more about the leg and knee neurovasculature here and test your knowledge with a quiz! Veins follow the arteries of the same name into the popliteal vein. In pathological circumstances, such as thrombophilia, it constitutes a common site of onset of deep vein thrombosis (DVT). ![]() Physiologically it contributes to the muscle pump of the lower extremity. Minor accessory arteries may also branch off the peroneal, posterior tibial and lateral sural arteries.Ī clinically important venous plexus is present in the soleus muscle belly. The peroneal and posterior tibial arteries are direct branches of the popliteal artery and arise in the popliteal fossa. The superior branch arises from the popliteal artery while the inferior branch arises from peroneal artery (fibular artery) or the posterior tibial artery. Blood supply is provided by two main branches. The soleus is innervated by the anterior rami of S1 and S2 spinal nerves, carried by the tibial nerve into the posterior compartment of the leg. (refers to the functions of posterior leg muscles Soleis is for posture, while Gastrocnemius is for explosive movements) Posterior surface of calcaneus (via calcaneal tendon) Soleal line, medial border of tibia, head of fibula, posterior border of fibula This article will outline the morphology of the soleus muscle, as well as its functional and clinical anatomy. The size and shape of the triceps surae muscle bellies determine the interindividual differences of human calves’ appearance - from slim to rather robust. They both insert on the calcaneus via the calcaneal tendon and act in many basic activities, such as walking, running, and leaping. Together with the gastrocnemius, they form the three-headed group of muscles referred to as the triceps surae. It also allows us to maintain an upright posture due to its important role as an antigravity muscle. Soleus’ contraction results in strong plantar flexion. These two muscles, along with the plantaris muscle, belong to the group of superficial posterior compartment calf muscles. The soleus muscle is a wide flat leg muscle found on the posterior leg. It runs from just below the knee to the heel and lays immediately deep to the gastrocnemius.
