1) Homeostasis
Language
English
Description
In order to understand homeostasis in a natural setting, this program observes what happens to the body during a marathon race. By monitoring the various physiological responses of one of the runners, we show the many changes and adjustments being made in the body as the race progresses. The data obtained from the runner are used to explain in detail how the body regulates temperature, blood oxygen, blood glucose, water balance, heart rate, breathing...

Harvard professor Larry Lessig has become a true hero to artists, authors, scientists, coders, and opiners everywhere as one of the founding authorities on copyright issues. As corporate interests have sought to rein in the forces of Napster and YouTube, Lessig has fought back, appearing recently before the U.S. Supreme Court to extend copyright protection from 50 to 70 years. The net's most celebrated lawyer, Lessig chairs Creative Commons, a nuanced,...

This program looks at the many roles played by muscle and skin in our everyday lives. Topics include muscles and movement; cardiac, smooth, and skeletal muscle; detailed structure of a skeletal muscle; types of muscle contraction and movement; muscles and posture; homeostasis; and the important roles played by skin, hair, nails, and glands.

The topic of bones and joints is explored in this program with Dr. Lyle Micheli at Boston Children's Hospital. Dr. Micheli runs the world's leading orthopedic clinic for young athletes, where the most common types of sports injuries, such as acute impact damage, are treated. The structure and function of the knee are clearly illustrated as we follow the diagnosis and treatment of injuries suffered by the Harvard University football team. The program...

In action or at rest, the human body is always in motion. This program uses vivid animations and real-life examples to show how the musculoskeletal and cardiorespiratory systems work and how they influence and respond to movement. Chapters include Introduction, The Skeletal System, The Muscular System, The Respiratory System, The Circulatory System, and Conclusion.

Description
This program deconstructs the human skeletal and muscular systems, two interdependent assemblies that endow the body with structure and movement. Beginning with an introductory overview, the video identifies the body's bones by dividing the skeleton into its axial and appendicular components, analyzes bone composition, describes the process of bone repair, and categorizes bone and joint types. The program then shifts focus to the skeletal muscular...

How can biomechanical principles be used to enhance physical performance? This program explains how to calculate velocity, acceleration, and momentum involving major types of bodily motion; distinguishes between two types of balance while discussing the concept of center of gravity and showing how to calculate force; and investigates the principles of fluid mechanics, including buoyancy, displacement, and resistance. Chapters include Introduction,...
9) Muscles
Language
English
Description
In this program, the diverse nature of muscle tissue is examined, from its gross structure to its detailed microstructure, where chemical energy is harnessed to produce movement. As muscle forms the basis for much of a person's body shape, we explore the ways in which this shape can be changed by the activities we perform. The program provides a complete introduction to the following topics: Location and uses of smooth, skeletal, and cardiac muscles...

Description
This program explores the skeletal system, with an emphasis on its importance in providing structure and support for the body. Topics include how the skeletal and muscular systems work together to enable movement; the relationship between joints and bones; connective tissue; functions of the skeletal system, including support, protection, movement, storage, and blood cell production; and types of bones and joints.
11) Moving parts
Language
English
Description
This program shows how the cerebellum coordinates muscle activity and how position sensors in the muscles and joints and the balancing mechanism of the inner ear function. The motions of a water-skier show how muscles, joints, and organs link up. The role of joints is explained, and a look at the interior of a human knee shows clearly how lubricating fluid is produced.

This program demonstrates, on a microscopic level, what happens when a kung fu master is at work: how muscles work, how two types of molecules telescoping against each other produce enormous strength as they work in large numbers, how muscles of the heart and digestive tract move without conscious direction.

Description
This program looks at the human body in motion, studying the interaction of the skeleton and muscles and the ways in which engineers and designers imitate these systems. Demonstrating how bones allow mobility while also providing protection, the program examines skeletal strength, calcium's importance, the internal structure of bones, and their dependence on muscles for cohesion and power. Linking architecture, machine design, computer science, and...

When used with delicacy, the hand is capable of manipulation that goes far beyond what might be expected of its mechanical design. This program demonstrates how the hand functions, spotlighting the opposable nature of the thumb, and how the nerve network and blood vessels deploy. The pathologies of common damage, including carpal tunnel syndrome, wrist fractures, "mallet finger," and degenerative dysfunctions, are investigated as well.

Description
The ankle, a major weight-bearing joint, is injured more than any other part of the body. After examining the surface features of the foot and ankle, this program probes the deeper layers, highlighting major bones, muscles, ligaments, blood vessels, and nerves. Special attention is given to the arches and the ankle joint with respect to stability. Common ankle and foot injuries, such as sprains and fractures, are also explained.

Description
Although it is a major weight-bearing joint, the knee is surprisingly flexible in all manner of forward, reverse, and lateral motions. This program addresses the intricate mechanics of the knee joint's musculature, tendons, ligaments, and cartilage. In addition, traumas to the menisci and the collateral and cruciate ligaments-the most commonly damaged structures-are described.

Description
A ball-and-socket joint capable of a complex range of motion, the shoulder achieves its mobility through the sacrifice of stability, relying on surrounding muscles and tendons for strength. This program presents the technical specifications of the shoulder: what muscles sheathe it, how it functions, and its range of motion. Conditions such as bursitis, tendonitis, dislocation, and fracture of the clavicle are also discussed.

This, the first of two programs on the senses, looks at those sense receptors that depend on contact with the immediate world: taste buds, touch sensors, and olfactory cells. These receptors also sense heat, pain, and pressure. The complex world just beneath the skin is re-created with realistic models, showing events like the pulling of a hair seen from the viewpoint of the root.

While it's long been believed that both your body and your brain deteriorate over time, recent studies show that may not always be the case. Some brain functions improve as we get older while others don't fully develop until later in life. In this episode, we explore your brain and how it doesn't always act its age. Through a series of games and experiments, you'll discover how your daily routines might be aging your brain, and how you can actually...
