The flexor digitorum pedis superficialis muscle ( Latin for "superficial toe flexor of the foot") is a flexor of the first and second toe joint that occurs in quadruped animals . In addition, he stretches the ankle . It is not trained in humans.
The muscle originates from the femur . The muscle belly lies between the two heads of the gastrocnemius muscle . The insertion tendon is part of the Tendo calcaneus communis (common heel tendon cord) and widens over the heel bone tuberosity ( Tuber calcanei ) to the so-called heel bone cap and attaches itself to this point. Under this first approach is a bursa ( Bursa subtendinea calcanea ) whose swelling as eggs bile is referred to. The tendon continues on the foot as a superficial flexor tendon and inserts plantarly on the corolla .
In horses , the muscle is purely sinewy and, together with the peroneus tertius muscle, forms what is known as the tension saw construction , through which the movements of the knee and ankle are synchronized.
A dislocation (dislocation) of the tendon of the muscle due to the tearing of the retaining straps on the calcaneus bone occasionally occurs in dogs, cats, horses and cattle. The outward dislocation is more common. Treatment is surgically.
