As for the muscles that move the joint of the foot, these include the muscles that raise it and the muscles that lower it. The levator muscle is a large muscle lying on the front side of the inner cane. This muscle starts from the outer part of the head of the inner cane, goes forward, deviates, passes along the shin and is directed towards the big toe. It adjoins the place close to the root of the big toe and lifts the foot upward.
Another muscle grows from the head of the outer cane. A tendon grows from it, adjacent to a place close to the base of the little toe, which lifts the foot upward, especially when the first muscle acts in concert with it, and their action occurs evenly and directly.
As for the depressor muscles, a couple of them grow from the head of the femur, then they go down and fill the inside of the back of the leg with meat. From these muscles a tendon grows - one of the largest tendons, that is, the tendon of the heel. It adjoins the heel bone and pulls it back, sloping outward. This is the reason why the foot is stable on the ground.
The said muscle is assisted by another muscle, the color of an eggplant, growing from the head of the outer cane. This muscle goes down and adheres to the bone on its own, without forming a tendon and remaining fleshy to the end. It attaches to the back of the heel, above the attachment of the previous muscle. When these muscles or their tendons become damaged, the foot becomes inactive.
There is another muscle from which two tendons branch; one of them flexes the foot, and the other extends the big toe. The fact is that these tendons start from the head of the inner cane, at the place where it meets the outer cane and descend between them, branching into two tendons. One of the tendons is attached below to the tarsus in front of the big toe; With the help of this tendon, the foot lowers.
Another tendon arises from a part of the said muscle, further than the origin of the first tendon. This part sends a tendon to the first joint of the thumb and extends the thumb, sloping it inward.
Another muscle grows from the outer head of the femur; it adjoins one of the two heel muscles, then separates from it, bypassing the inside of the lower leg. From this muscle grows a tendon that runs along the bottom of the foot and spreads under the entire foot, similar to the muscle that spreads along the inside of the palm, and for the same usefulness.
