Human Skeleton Functions and Structure

The video tutorial explains the human skeleton, highlighting its importance in providing shape, support, and facilitating movement. It covers the four main parts: the skull, which protects the brain; the ribcage, which safeguards vital organs like the heart and lungs; the backbone, which aids in flexibility and movement; and the limbs, which include the forelimbs and hindlimbs, essential for mobility. The tutorial concludes with a recap of these components and their functions.
