Muscle Types and Functions

The video tutorial explains the three types of muscles in the human body: skeletal, cardiac, and smooth. Skeletal muscles are voluntary and attached to the skeleton, allowing movement. Cardiac muscle is found only in the heart and is involuntary. Smooth muscle is also involuntary and is located in various parts of the body, including the digestive tract, where it helps move materials through the system.
