The common inhibitor innervates muscles proximal to the autotomy fracture plane in Carcinus maenas.
The neuron common to proximal leg muscles of the crab Carcinus maenas projects to the propus opener nerve. Inhibitory effects include hyperpolarizing postsynaptic potentials, prolonged muscle fiber membrane hyperpolarization upon repetitive stimulation and suppression of force development by excitatory motorneurons of the anterior levator. The soma of the common inhibitor of fifth legs is located ventrally along the ganglion midline, contralateral to its axonal projections.
