1. Electrophysiological studies of mechanoreceptors within the ABRM of the mussel, Mytilus edulis have revealed two types of tension receptors. Multiunit recordings were made from an isolated nerve-muscle preparation during stretch with platinum hook electrodes. The responses observed were: type one, showing receptor firing during the rising phase of applied tension and type two, showing receptor firing during the falling phase. Based on electrical waveforms of multiunit recordings, both types of receptors seem to fire independently of each other, and can be reliably excited by the stimulus.

2. These mechanoreceptors are suggested to be part of a system which supplies information to the pedal ganglion for motor control of the ABRM.
