Crosscut saw into the wood. Many sawtooth patterns have four cutters; each cutter that cuts to the left of the blade is paired with another that cuts to the right of the blade. Adjacent to the cutters there is generally a raker. The void on either side of the raker is known as the gullet. A raker is what does the actual removal of the wood that is being cut. The raker follows the cutters, paring the bottom of the kerf like a chisel or plane. As the raker pares the bottom of the kerf, a strip of wood is lifted upward,
Heel stretch the foot downward. It is accompanied by a "fourth head", the slight plantaris muscle, the long slender tendon of which is also attached to the heel bone but not visible. The compressive forces applied to the foot are distributed along five rays, three medial (side of big toe) and two lateral (side of little toe). The lateral rays stretch over the cuboid bone to the heel bone and the medial rays over the three cuneiform bones and the navicular bone to the ankle bone. Because the ankle bone is placed over the heel bone, these rays are adjacent near
