Location of the extrinsic and intrinsic muscles in the leg. The larger muscles controlling movement of the foot and the toes are located in the leg. We refer to them as the extrinsic muscles of the foot. This allows for the foot to be less bulky and capable of fine movements with fewer restrictions. Smaller muscles located in the foot are referred to as intrinsic muscles of the foot, and they move the toes and support the arch of the foot.
