Human Muscular and Skeletal System

This video tutorial covers the human skeletal system, joints, and muscles. It explains the structure and function of the skeleton, including its role in supporting the body, protecting vital organs, and facilitating movement. The video also describes various types of joints, such as hinge, ball-and-socket, saddle, and pivot joints, highlighting their specific functions. Additionally, it discusses different muscle types, including skeletal, cardiac, and smooth muscles, and their roles in voluntary and involuntary movements.
