The Ultimate Home Study Course On Human Anatomy & Physiology
is an electronic book, which will provide you with the full composition of the human body. It contains many color images of individual sections of body parts, many X-Rays and many of views of human body parts from various sides. Notify you of the composition of the body of the male sex, women, and also the child's body. Very suitable for students of medicine, general medicine, and it may be used by students of high schools.
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
