Human Muscular System Concepts

The video tutorial covers the third part of a lesson on the skeletal and muscular systems. It begins with a recap of previous modules on the skeleton and joints, then introduces the muscular system, explaining that muscles are tissues covering bones and facilitating movement. The tutorial details the types of muscles: voluntary, which are under our control, and involuntary, which function autonomously. It explains how muscles work in pairs, using biceps and triceps as examples, and concludes with a recap of the lesson's key points.
