Combined reflex actions by several proprioceptive inputs in the rock lobster walking legs

In rock lobsters,Panilurus vulgaris, Jasus lalandii, the coxo-basipodite (C-B) and the mero-carpopodite (M-C) joints are mainly involved in body posture and in locomotion. In order to determine the functional relationships between these two joints the reflex effects induced by the C-B and M-C proprioceptors onto the muscles of their own joint (intrasegmental reflexes) or of the other joint (intersegmental reflexes) have been studied.
