Human Body in Action - Skeletal & Muscular Systems (VIDEO)

Our bones serve many purposes. Find out more about the five functions of the skeletal system: form, movement, protection, mineral storage and marrow production. See the inner workings of bones and how they interact with our muscles. Learn the difference between bone and cartilage plus the four types of movable joints. Together the two systems control our movements; clear illustrations and images demonstrate this process. Learn also about the importance of exercise and muscle health.
