Function of the cells in the motor root of the nervus trigeminus in the cat

The purpose of this investigation is to determine through experimental-histological methods the function of certain large and small nerve cells found in and about the motor root of the nervus trigeminus in close proximity to the ganglion, semilunare. These cells were noted in a previous paper and it was suggested that some of them in . :the connectivetissue sheath of the motor root were probably mandibular or maxillary-ophthalmic ganglion cells that had migrated centrally along the path of the motor root and others inside the motor root might be proprioceptive (muscle) sense cells. Similar cells have been recorded for the eye muscle, facial, and hypoglossal nerves. Those found in the eye-muscle nerves, especially in the ocnlomotor nerve, have received considerable attention, and the consensus of opinion is that they are concerned with proprioceptive sense.
