Anatomic Changes in the Autonomic Nervous System with Age
A number of global changes occur in the human nervous system with age. These changes affect the Autonomic Nervous System as well as other parts of the nervous system. The weight and volume of the nervous system reaches a maximum at puberty and later begins a progressive decline beginning in middle age. Some areas are relatively spared, such as the parietal lobes and brain stem. In the peripheral nerves, there is a loss in fiber number and a loss of myelination. The number of neurons is reduced with age, although the extent of loss has been difficult to assess in human. (more…)
