This course is designed as a cross-reference guide focusing only on the most relevant topics. DOWI's goal is to connect the 'dots' of learning that will help you achieve your goals in understanding the topic.

The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body. Also, the human skeleton is the internal framework of the body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together.
