Detail the parts of a drop of blood created from an angle

A blood drop striking a smooth surface at a 90° angle will result in an almost circular stain; there is little elongation, and the spines and satellites are fairly evenly distributed around the outside of the drop. Below 75°, spines begin to become more prominent on the side of the spatter opposite the angle of impact.
