The muscular system of the American lobster contains two types of muscles, fast and slow muscle fiber, which are paired either individually or are mixed together. The muscles in the lobster's crusher claw (the largest claw) consists of this slow muscle and the cutter claw (the smaller claw) consists of fast fibers in order to conduct quick maneuvers.
The abdomen of the lobster has two masses of muscle which are divided into the top surface (or dorsal) which functions as extenders and the underside abdominal muscles (ventral) which function as flexors.
The lobster's tail contains axons which serve as a significant muscular specimen for it's reflexes. Some such reflexes are caused when the abdominal muscles are stimulated and the lobster's tail flips upward causing it to do a somersault, propelling it backward, flipping it right-side-up, or causing it to land on its back.
