Cover Story: Invertebrates show more variation in muscle organization than vertebrates. The Procambarus clarkii opener muscle has three phenotypic regions (distal, central, proximal) yet is innervated by only one excitatory neuron. These regions have varied biochemistry and physiology. Central fibers generate the largest force with the longest sarcomeres; however, serotonin does not increase force generated by central fibers more than other regions. This finding was surprising since tension receptors sensing the shearing forces are located at the distal end of the apodeme (cuticle invagination). This study demonstrates the malleability of the motor unit. View this paper.
