The anterior extensors lie within the anterior compartment located at the ventrolateral region of the lower leg where they form its surface structure. Their tendons are particularly prominent on the dorsum of the foot. They include the tibialis anterior, the extensor hallucis longus, and the extensor digitorum longus.

The extensor digitorum longus muscle has three points of origin. It originates at the lateral tibial condyle, the ventral side of the fibula, and the interosseous membrane, and merges into a tendon above the superior extensor retinaculum.

Below the inferior extensor retinaculum, it divides into four tendons inserting at the dorsal aponeurosis and the bases of the distal and middle phalanges of the second through fifth toes. About 90% of people have an additional fifth tendon running towards the lateral foot edge and inserting at the fifth metatarsal bone. All anterior muscles are innervated by the deep fibular nerve.

In the full version of this video, we will cover the following points about the extensor digitorum longus muscle using a 3D model:
- anatomy and location;
- origins, insertion and innervation;
- functions of the extensor digitorum longus muscle.
