It describes how nociceptor or pain receptors respond to painful stimuli. Some of the chemical substances that modulate the transmission of pain include histamine, substance P and prostaglandins. Information is presented on acute and chronic pain and different types of pain, namely neuropathic pain, phantom pain and central pain.
