A comprehensive overview of the mechanisms of muscle contraction and non-muscle cell motility at the molecular and cellular levels, along with a description of the various experimental techniques applied to these systems. Considers the regulation of contraction in skeletal, cardiac, and smooth muscles and in the actin-myosin sliding coupled with ATP hydrolysis; protoplasmic streaming, amoeboid movement, ciliary and flagellar movement, and various aspects of movement during cell division.
