Vertebrate Skeleton Functions and Anatomy

The video explores vertebrate skeletons, explaining their structure, function, and importance. It covers bones, cartilage, and joints, highlighting their roles in protection, support, and movement. The video includes an activity to identify animals by their skeletons and compares human skeletons with those of other animals. Key parts like the skull, backbone, rib cage, and limbs are discussed, along with the role of girdles in movement. The video concludes with a review of key concepts.
