What is the origin of the extensor digitorum longus muscle?

The extensor digitorum longus muscle originates from the proximal half of the medial surface of the fibula and the lateral condyle of the tibia. This location allows the muscle to effectively extend the toes and assist in dorsiflexion of the foot due to its position and line of pull. The attachment to both the tibia and fibula provides a stable base for generating the necessary movements for the toes when walking or running, reflecting the functional importance of this origin for activities that require toe extension and ankle mobility.
