Final answer:
The site of action for a spinal cord stimulator is in the spinal cord itself. It delivers electrical signals to interfere with pain signals and provide relief from chronic pain.
Step-by-step explanation:
The site of action for a spinal cord stimulator is in the spinal cord itself. A spinal cord stimulator is a device that is implanted in the spinal cord to manage chronic pain. It works by delivering electrical signals to the spinal cord, which interfere with the pain signals that are being sent to the brain.
The electrical signals generated by the spinal cord stimulator act on the neurons in the spinal cord, specifically targeting those that transmit the pain signals. By interfering with these pain signals, the spinal cord stimulator can provide relief from chronic pain.
