Principal neurons of the lumbar sympathetic ganglia increase in number with body size.

Abstract excerpt

Neuron number appears to be matched to body size during early development by the modulation of the processes of proliferation and naturally occurring cell death. However, body size increases rapidly as the juvenile becomes an adult, long after these processes cease to operate. The present study shows that principal neurons of lumbar sympathetic ganglia increase in number four- to fivefold during postmetamorphic...
