Locomotion and Movement.

This chapter explains how the human body moves. It separates movement from locomotion, lists the three kinds of movement our cells show, and compares skeletal, visceral and cardiac muscle. It then opens up a skeletal muscle down to the sarcomere and its actin and myosin filaments, walks through the sliding filament theory step by step, and contrasts red and white fibres. The second half counts the 206 bones of the axial and appendicular skeleton, classifies joints, and ends with common muscle and bone disorders.
