Abstract
The convoluted M bands of the protozoan Stentor coeruleus straighten before the animal contracts. Mechanical stimulation initiates contraction locally, and then contraction spreads over the animal with a propagation velocity of 5 to 25 centimeters per second. The contractile wave may spread in both anterior and posterior directions. Electrical stimulation initiates contraction in all areas of Stentor simultaneously.
