[Morphometric features of changes in the neurons of the jejunum in the aging body]

It is common observation that in aged people, the number of processes in long-axonal and equal-axonal neurons decreases. Quantitative ratio of these neurons changes, as well. While at mature age long-axonal/equal-axonal ratio is 3 : 1, at old age it makes 1 : 2. In dogs, unlike in human beings, the old age influences neither the number of processes, nor the quantitative ratio of the neurons mentioned.
