Did you know that antlers help an animal regulate its body tempature? Have you ever seen how ribs function to accommodate the movement of the lungs? Do you know which animal has the strongest jaws, the most developed forelimbs, the most powerful legs? Skeleton, part of the Eyewitness video series, has these and many, many more facts about the toughest part of our bodies. Skeleton is an ideal introduction to anatomical science for young viewers. Its visuals are fresh and interesting, its documentary footage is sharp, and Martin Sheen's narration is quite effective. Budding scientific minds will be fascinated by how our skeletons maintain bodily harmony, protect our internal systems, and give us balance and stability. This is another well-done chapter in the Eyewitness series. --Brendan J. LaSalle
