Introduction to the muscular system

This video provides an introduction to the muscular system, explaining the different types of muscles, their properties, and their roles in the body. It covers skeletal, cardiac, and smooth muscles, detailing their functions and locations. The video also explores the major groups of skeletal muscles by body region and discusses clinical aspects such as muscle paralysis and atrophy. Finally, it reviews the key points covered in the video.
