The Musculoskeletal SystemWithout its skeleton, the human body would be a shapeless bag of flesh. Without muscles, it would be as immobile as a tree. Together, the skeleton,joints and muscles of the human body create an astounding array of motion, form the graceful movements of a ballerina, to the powerful strides of an athlete, to the intricate precision of a musician's fingers. This first part of The Human Body series examines the structure of our skeleton and the function of our muscles. Viewers learn how our bones provide the rigid support necessary to hold any position, while our joints give us the remarkable range of motion needed to run, dance,climb, or simply to walk, sit and bend. In addition, we discover how our muscles and associated tendons and ligaments are constructed to allow them to change shape functions, as well as how bone growth occurs. This video also takes viewers on a tour of the most wondrous part of the skeleton, the skull, seemingly a solid bone with teeth, but actually far more than that. The program also explores the amazing human hand one of the most versatile structures among all species because it performs a most versatile structures among all species because it performs a remarkable range of tasks, from wielding a hammer to playing a Mozart sonata. Our feet, ankles and knees are also constructed to perform multiple tasks and endure incredible stress over the course of a lifetime. With commentary form medical experts and specialists in sports medicine, The Human Body -- The Musculoskeletal System offers viewers a unique perspective on the body system which allows us to walk, run,dance and move through life. The Nervous SystemAre you right- or left-handed? Do you remember your first day of school? What are you thinking right now? The answers to these questions go right to the "brains of the operation," the incredible nervous system of the human body. This second part of The Human Body series explores the brain, spinal cord, nerves and the trillions of neurons, or nerve cells, that make our bodies uniquely human. Experts in neuroscience help us understand why the human brain is a marvel of structure and function. Viewers learn about left brain and right brain activities, and the purpose and function of the cerebellum,cerebrum, cranial nerves and other parts of the brain. The program also examines the interaction of the spinal cord and nerve endings, as well as fascinating concepts like involuntary and voluntary brain activity and reflex and feedback functions. Viewers explore the five senses: our eyes, which transform shades of light into the phenomenon of sight; our ears, which convert variations in air pressure into hearing; our nerve endings, which translate contact to touch; and our tongues and noses which give us taste and smell. The sixth sense -- balance -- is also explained. The Human Body -- The Nervous System offers fascinating insight into how our brain sets us apart from all other vertebrates. It gives us the ability to speak, reason, remember and engage in complex thought, as well as the capacity to feel compassion, sadness, anger, joy and love. Major Systems and OrgansThe human body is a wondrously complex machine made of flesh, bone,muscles, organs, blood vessels and highly specialized systems that function together to sustain life. This fascinating third part of The Human Body series examines the incredible "machine," from simple cells,to DNA, the body's building blocks of life, to the major systems and organs. Using animation combined with live-action footage and commentary from medical specialists, this program illustrates how the major systems and organs function. Viewers learn how the reproductive system generates new life and how the stomach, intestines and other organs of the digestive system convert solid matter into the fuel of life. We also discover how the lungs and respiratory system take in oxygen that sustains life, and how the heart and circulatory system connect all body systems, providing a delivery system for the oxygen. In addition,the program explores the lymphatic, immune and other supporting systems. Finally, viewers explore the structure and functions of our skin, the body's largest organ, which protects us from the outside environment. The Human Body -- Major Systems and Organs enhances viewers'understanding of the truly miraculous machine that is the human body. The Just the Facts Learning Series brings you the finest in educational programming and features fast-paced format that makes learning fun.
