The document is a biology worksheet on chapter 11 which covers locomotion and support. It contains questions about the human skeleton, types of skeletons, muscle and bone diagrams of the arm, and diagrams of joints. The questions assess labeling parts of diagrams, naming structures and their functions, types of joints, antagonistic muscle pairs, and the process of muscle fatigue.
