Cholinesterase activity was investigated in the heart of the developing chick from the 6th to 20th day of incubation. The earliest cholinesterase-positive nerve cells and fibers could be demonstrated between the 7th and 9th day. On the 13th day the nervous structure attained full development comparable with that seen in the hatched chicken. The number of ganglia increases up to the 15th day, and remains constant thereafter. The right ventricle is associated with the largest number of ganglia.
在孵化第6天至20天的发育中的小鸡心脏中研究了胆碱酯酶活性。最早的胆碱酯酶阳性神经细胞和纤维可在第7天至第9天之间显示出来。在第13天，神经结构发育完全，与孵出的小鸡所见的结构相当。神经节数量在第15天前增加，此后保持恒定。右心室与最多数量的神经节相关。
