anterior: the front.

arch: the portion of the bottom of the foot that does not touch the ground. The precise technical term is metatarsal arch.

ball: the swelling at the inner side of the foot where the big toe joins the head of the first metatarsal bone. This is the main line of flex for the foot and is sometimes referred to as the joint.

dorsum: the top of the foot.

dorsiflex: the upward flexing of the foot so that the upper portion of the foot (also known as the dorsum) approaches nearer to the leg.

lateral: the outer side of the foot. An easy way to remember this is that when you are moving laterally, you are moving side-to-side.

medial: the inner side of the foot. An easy way to remember this is that the medial side of the foot is at the median line of the body.

plantar: the bottom or sole of the foot.

plantar flex: the downward flexing of the foot so that the forefoot moves further away from the leg.
