The first part focuses on movements at the synovial joints-gliding movements (typified in the wrist area); rotation movements (medial and lateral); and angular movements (flexion, extension, abduction, adduction, and circumduction). Special movements include inversion, eversion, protraction, retraction, pronation, elevation, and depression. A second part examines the actions of muscles in specific areas of the body, including face, head, spine, extremities, and abdomen.
This collection of 52 video clips (30 seconds to 2 minutes 30 seconds each) combines high-quality film footage and detailed animations to take a close-up look at the body’s building blocks, the architecture of the body, the nervous system.
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 system-a detailed study of muscle cells, fibers, bundles, and connective tissue. The ATP-fueled process of muscle contraction is addressed as well.
