The aim of the present study to ascertain the mode of origin of the phrenic nerve and to provide a morphological basis for experimental studies of this nerve in the guinea pig. In sketches made of the dissections, in 10 male and 10 female guinea pigs adults, the modes of origin of the phrenic roots were demonstrated to arise from the fourth to the seventh cervical nerves. Four types of origin could be distinguished. The phrenic nerve of the guinea pig has three or four roots.
