The embryonic origin of the autonomic ganglia located in the walls of the thoracic and abdominal viscera has remained obscure in spite of many reports on the subject (reviewed by van Campenhout, '30; Yntema and Hammond, '47). The earlier descriptions of a vagal ectodermal source for the cardiac and pulmonary ganglia (Kuntz, '10; Abel, '12) have been generally accepted. However, their exact origin, neural crest or tube, has not been settled. As to the enteric ganglia there is no common point of view. Neural crest or tube of various levels as well as local mesenchyme have been described as embryonic sources. These problems can be clarified since in the chick a common embryonic rudiment of these ganglia is confined to a limited region. This part can be extirpated without subsequent reconstitution by adjacent cells. We have found that proper removal of the neural crest from post-otic and anterior spinal levels results in absence of the intramural ganglia of the lungs, heart, and digestive tract.
