What is Flexor Digitorum Longus?

Flexor Digitorum Longus is one of the three muscles in the lower leg bearing this name: Flexor Digitorum Longus, Flexor Digitorum Brevis and Flexor Digitorum Superficialis. This muscle is responsible for the bending or ripple of all fingers, except the large finger, found deep on the inside of the back of the foot under the gastrocnemius and Soleus, the large muscles of the calf. It runs down through the bones of the tibia, intersects the ankle and puts it on the base of each tip, where it stretches down to the underside of the distal bones of Phalang during the muscle contraction. Its fibers insert diagonally for most of its length into the tendon on the back of the muscle, which passes through the ankle to the back of the media malleol, a large bone protrusion of the tibia felt inside the inside. From there, the tendon passes over the kacánem or the bone of the heel, passes the bottom of the foot and inserts along the fibers of the muscle Kvadratus plantae in the form of four different tendons at the bottom of the distal phalanxes. Distal phalanxes are the last bones on the feet; Four Receiving tendons Flexor DigitOrum Longus are tendons second to fifth fingers.

In addition to the role of this muscle in bending the last four fingers, it participates in the plantarflexion of the entire foot at the ankle. Plantation plantarflex is primarily the responsibility of larger gastrocnemius, soleus and tibialis of the rear muscles. Flexor Digitorum Longus helps in this movement largely because it is so internally connected with the latter muscle, the rear of the tibialis, in its Path over the ankle joint.

Because Flexor Digitorum Longus comes not only on the body of the tibia bone, but also on the fascia of the rear tibialis rear - a fibrous tissue vagina surrounding the muscle - and because its tendon runs simultaneously with the effect of tibialis backward through the ankle joint. The tendon is also the main connecting structure in the middle or inside the arch of the foot along with the tendon flexor hallucis longus, which bends a large finger. As such, they participate in the support and maintaining the arch of the foot.
