The term “anatomy” is derived from the Greek word “anatémnein”, which means “to cut apart” or “to dissect”. Anatomy is the study of the makeup and structure of the human body. The study of human anatomy is often significantly facilitated through the use of human anatomy diagrams. The Human 3D software features numerous anatomy diagrams of the human body.
At the beginning of the modern age insights were gained into the structure of human organs through the dissection of corpses.
Anything that we can see with our naked eyes in this context is referred to as macroscopic anatomy. In order to be able to see the smaller dimensions, the microscope had first to be invented. This area is referred to as microscopic anatomy. With the advent of the electron microscope, microscopic anatomy has been supplemented with submicroscopic anatomy.
For the purpose of orientation, the human body is always described as if it is standing upright. There is a system in place by which certain points on the human body can be described precisely. For instance, the head is always considered to be at the top and the front of the body is forward, no matter what the actual position of the body.
As the human body grows, the proportions of the various regions and limbs of the body change because they grow at difference rates. This is especially evident when comparing the prenatal human body with that of an infant or toddler.
The skull of a six-week old embryo, for example, is as long as the rest of the body. In the newborn child the skull measures approximately one-quarter of the overall body length, while in a six-year old this ration changes to one-sixth. By adulthood the skull accounts of only one-eighth of the overall body length.
Bone growth is always closely related to the development of the organism as a whole. There are no absolutes in terms of skeletal proportions. There are, for example, differences between men and women in the distance from the base of the torso to the upper extremities. When compared with the male torso, the female torso is generally proportionately longer, but the woman’s arms are generally shorter. The female skeleton is overall lighter and somewhat less robust than the male skeleton.
