, In measuring the autonomic nervous system skin potentials, which of the following is true f
median nerve?
Stimulation can be on either side.
Stimulation must be on the opposite side of the body to where the potentials are mea
Stimulation must be on the same side of the body as the potentials are measured.
Certain symptoms may be indicators of neuropathy, which can a ect nerves of the autonom
nervous systems. Categorize the following statements:
Autonomic neuropathy P
Alteration to normal Blurring of vision W
gastrointestinal function Loss of the ability to urinate Lo
Blurring of vision Dizziness or fainting when
Di culty walking getting up at night
Dizziness or fainting when Erectile dysfunction

Dry skin
Alteration to normal
Erectile dysfunction gastrointestinal function
Loss of sensation in the feet
