We have used a retrograde labeling technique to identify motorneurons for each of the 30 body wall muscles of an abdominal hemisegment in the late stage 16 Drosophila embryo. Each motorneuron has a characteristic cell body position, dendritic arborization, and axonal projection. In addition, we have determined the neuroblasts of origin for most of the motorneurons we describe. Some organizational principles for the neuromuscular system have become apparent: (1) There is no obvious topographic relationship between the cell body positions of motorneurons and the position or orientation of the muscles they innervate; (2) motorneurons that innervate muscles of similar position and orientation are often clustered and have overlapping dendritic trees; (3) morphologically similar motorneurons are generally derived from a common neuroblast and innervate operationally related muscles; and (4) neuroblasts can give rise to more than one morphological type of motorneuron.
