Extensor Digitorum Longus is a muscle located in the anterior compartment of the leg that extends the four lesser toes and aids in dorsiflexion of the foot at the ankle joint. Its primary function is to facilitate foot movement, especially in activities such as walking or running.
The name "Extensor Digitorum Longus" is derived from Latin, where "extensor" refers to its function to extend, "digitorum" means "of the fingers or toes," and "longus" indicates its length, distinguishing it from other shorter extensor muscles.
Without the Extensor Digitorum Longus, a person would have difficulty lifting their toes and foot, impairing normal walking or running and making activities that require precise toe movements challenging, which could affect balance and coordination.
