Muscles of the Foot. The muscles acting on the foot can be divided into two distinct groups; extrinsic and intrinsic muscles. The extrinsic muscles arise from the anterior, posterior and lateral compartments of the leg. They are mainly responsible for actions such as eversion, inversion, plantarflexion and dorsiflexion of the foot.

What are the intrinsic muscles of the foot?

They can be divided into those situated on the dorsum of the foot, and those in the sole of the foot. Whilst many of the extrinsic muscles attach to the dorsum of the foot, there are only two intrinsic muscles located in this compartment – the extensor digitorum brevis, and the extensor hallucis brevis.
