Variations in neuron size in the avian intestinal myenteric plexus.
The size of the neurons in the myenteric plexus of the duodenum, jejunum, ileum, rectum and cecum of chick and adult domestic fowl (Gallus gallus) was estimated using a histochemical technique for NADH diaphorase activity. The mean size of the neurons varied between different regions of hte gut and increased with age. In both chicks and adults the largest neurons were observed in the distal part of the cecum. The differences between the estimated neuron sizes in the chicks and adults are discussed and the data compared with similar estimates of neuron size in mammals.
