The study of the structure of the body is called anatomy. Surprisingly, this science has only developed in the last few centuries. Before then, even the basic structure of the human body remained shrouded in mystery as dissection of the human body was forbidden by most religions. As technology advances, we gain the tools to study the body in greater detail. The microscope, first described just three hundred years ago, opened up details of the structures of the body too small to be seen by the naked eye. The microscope allows us to look at the finer detail of the structure, called the histology, of the body. The smallest entities of life are called cells.
