Approximately 650 different muscles of varying size and shape, working in conjunction with over 200 bones, make it possible for the human body to move. This skeletal system is also essential for internal bodily functions to take place. Animated skeletons and 3D pictures can be of great help in visualizing the structure of the human body.
Bones and muscles shape the figure of the human body, and bring it into an upright position against the force of gravity. Even when we are sitting or standing still, our skeletal system is constantly making small corrections to our posture.
Leonardo da Vinci wrote: “Movement is the root of all life.”
Movement, in the context of the human body, means the contraction of our muscles in which the billions of protein molecules play their part. These contractions, in turn, cause the skeletal bones to move.
Muscles account for up to 35 per cent of total body weight in women and 50 percent in men.
Our active human skeletal system supports a variety of bodily functions:
- Movement and support of the skeleton,
- Supporting and protecting the functioning of internal organs (stomach, bowels, bladder),
- Expression of emotions,
- Production and storage of heat,
- Support of the circulatory systems.
The sum of all the muscles in the human skeletal system is referred to as the musculature or muscular system. Their main function is to produce work resulting from muscle contraction (Latin for “draw together”). The sum of all the bones in the human body is referred to as the skeleton.
Advances in computer software have made it much easier to learn about the human body. The Human 3D software product provides a collection of skeleton 3D pictures and skeletal joints to assist the user in understanding the structure of the human body. Animated skeletons and pictures of the skeletal system also help the user grasp the functions and nature of the body.
