Skeletal System Concepts Assessment

The video explains the skeletal and muscular systems, highlighting the differences between bone and cartilage, and detailing the axial and appendicular skeletons. It covers the types of joints and their roles in movement, and discusses common disorders like myasthenia gravis, muscular dystrophy, tetany, arthritis, osteoporosis, and gout. The importance of a healthy lifestyle for maintaining these systems is emphasized.
