Healthy Skeletal and Muscular Systems: Your Muscular System

The video explains that everyone has the same number of muscles, but their size and strength vary. Muscles are tissues made of fibers that contract and relax to enable movement. There are three types of muscles: cardiac, smooth, and skeletal. Cardiac muscle is found in the heart, smooth muscle in the stomach and intestines, and skeletal muscle is attached to bones, allowing movement. Tendons connect muscles to bones, and the skeletal system provides a framework. Together, they form the musculoskeletal system.
