What is Flexor Hallucis Longus?

Flexor hallucis longus is the muscle of the rear section of the lower leg. Located deep in the calf next to Flexor Digitorum Longus and Tibialis Rear, is responsible for bending or ripple a large finger. It is relatively centrally on the back of the foot under the larger gastrocnemius and the soleus muscles of the calf, even though it is closer to the side or fibular side of the foot, while the tendon passes through the ankle joint and runs under the feet to the large tip. As such, this muscle is involved not only on the bending of the large tip, known as Hallux, but also from the ankle.

coming about a third of the way down the back or rear aspect of the fibular bone, the flexor hallucis longus also finds its origin on the interosseous membrane that divides the leg into its front and rear compartments. In addition, it is formed from several fibrous tissues surrounding near muscles, such as fascia surrounding the rear muscle situation of Tibialisated just above the calf. All of these fibers descend and converge and create tendons. Like the back of Flexor Digitorum LongUs and tibialis, it is a relatively large tendon that leads to most of the muscle length and after the muscle fibers decrease, it intersects the ankle.

Hallucis longus tendon is sloping obliquely behind the lower part of the tibia on the inside of the ankle. Then it runs between the bone of the talus ankle and below it Kacánou or the heel of the bone through a niche called Sustentaculum Tali. Finally, the underside of the foot along the tendon of Flexor Digitorum Longus and connects to the base of the distal phalanx of the large tip, the last bone in the hallux. This insert point allows flexor hallucis longus to act not only at the distal interphalangal joint or the last joint at the tip, but also on the metatarsophalangeal joint, the second joint at the tip, pulling down on the distal phalan to turn the entire tip.

In addition to this muscle in a large finger, it participates in plantarflexion of the entire foot at the ankle. Plantarflex is primarily the responsibility of largerGastrocnemius and Soleus muscles, plantarflex pointing foot down to the ankle, as can be seen in a dancer that directs her fingers. Flexor Hallucis Longus, larger and stronger than the neighboring muscles of Tibialis Rear and Flexor Digitorum, which also support ankle plantarflexi, is the secondary agent of this joint action.
