The foot muscles have two main categories, called extrinsic muscles and intrinsic muscles . The foot’s extrinsic muscles originate in the lower leg and insert into different portions of the foot to allow for gross motor movements such as plantar flexion, dorsiflexion, inversion, and eversion. Intrinsic muscles are located within the foot and are responsible for more fine motor movements such as digit flexion, extension, and abduction. The Intrinsic muscles can be further broken down into the dorsum side and the plantar side.
