Autonomic Nervous System Testing

A utonomic nervous system testing is used to document diabetic autonomic failure. Diabetic autonomic failure is defined as impaired function of the peripheral autonomic nervous system and can be divided into two categories: 1) autonomic neuropathy, in which there is a structural lesion of the peripheral autonomic neuron and 2) functional autonomic failure, in which no known structural lesion oc...

Despite these findings, mostly in the cardiac, esophageal and colon tissue 5,14,15, no correlation exists between the intensity of neuronal destruction and dilation of the heart or other microscopic indices of myocarditis in the chronic phase14. Histopathologic foci of damaged nervous tissue are found in a diffuse and irregular distribution. Neuronal parasitism, with periganglionitis and degene...

'Autonomic' nervous system.

The functions of this system were elucidated in a series of important physiological experiments in the second half of the 19th century. Ernst and Eduard Weber in Leipzig stopped the heart by stimulating the vagus nerve whilst Claude Bernard and others reported the acceleration of the heart’s action with sympathetic stimulation. These opposing actions led Walter Gaskell [4] at Cambridge to condu...
