Human Rib Cage Outline With Sternum and Collarbones

A front view of the human rib cage fills the page in clean black outlines. Two long collarbones stretch out to the left and right across the top, meeting the sternum in the center. The sternum runs down the middle and ends in a narrow, pointed tip near the bottom. On each side, curved ribs wrap around in stacked rows, and you can see the short segments near the breastbone where each rib connects toward the front. The lower ribs sweep outward and downward to form a wide, open shape at the base. There is no background, so the whole page is just bones. Try coloring the collarbones, sternum, and ribs in three different colors so kids can see where each part begins and ends. It also works well as a labeling activity for a basic anatomy lesson, and the printable page gives plenty of room for notes.
