Extensor Digitorum Longus
The extensor digitorum longus is a muscle located in the inside upper-thigh.
It is easy to work out the function of the extensor digitorum longus muscle because an extensor is a muscle that causes a movement that increases the angle between articulating bones. The actions of the extensor digitorum longus muscle include extending the toes - especially the four lateral toes as the extensor hallucis longus extends the great toe.
