Inferior end of lateral supracondylar line of femur; oblique popliteal ligament: Weakly assists gastrocnemius in plantarflexing ankle Soleus: Posterior aspect of head and superior quarter of posterior surface of fibula; soleal line and middle third of medial border of tibia; and tendinous arch extending between the bony attachments
Soleus muscles have more slow muscle fibers than many other muscles. In some animals, such as the guinea pig and cat, soleus consists of 100% slow muscle fibers. [6] [7] Human soleus fiber composition is variable, containing between 60% and 100% slow fibers. [8] The soleus is the most effective muscle for plantar flexion in a bent knee position.
The sural arteries (inferior muscular arteries) are two large branches, lateral and medial, which are distributed to the gastrocnemius, soleus, and plantaris muscles. Sural means related to the calf. [1]
Blood vessels and nerves can also be affected by the pressure caused by any swelling in the leg. If the pressure becomes great enough, blood flow to the muscle can be blocked, leading to a condition known as compartment syndrome. Severe damage to the nerve and blood vessels around a muscle can cause the muscle to die and amputation might be ...
The superficial branch then continues onto the dorsum of the foot to supply sensory fibers to the skin there. The main deep neurovascular bundle at risk is the posterior tibial artery . It lies on the posterior aspect of the tibialis posterior and flexor digitorum longus muscle , and medial to the belly of flexor hallucis longus muscle .

The arteries that supply the posterior compartment of the thigh arise from the inferior gluteal and the perforating branches of the profunda femoris artery, [5] a major collateral branch of the femoral artery and part of the anterior compartment of thigh.
The soleal line, also known as the popliteal line (in older texts), is a prominent ridge on the posterior surface of the tibia. It is the site of many muscle origins and insertions, such as those of popliteus muscle , soleus muscle , flexor digitorum longus muscle , and tibialis posterior muscle .
