TED-ED: How your muscular system works - Emma Bryce

The video explains the muscular system, which consists of over 650 muscles responsible for movement and vital functions. It covers the three main muscle types: skeletal, cardiac, and smooth, detailing their roles and control mechanisms. Muscle contractions are categorized into shortening, lengthening, and stabilizing, each serving different functions. Skeletal muscles are under voluntary control, while cardiac and smooth muscles are autonomously controlled. The video also highlights the role of muscles in heat production, essential for maintaining body temperature.
