2. Pain that endures beyond the time of normal healing
3. Idea that pain results from a combination of impulses from nerve fibres
7. Continuous discomfort, associated with a malignant condition. It becomes increasingly intense as the underlying condition worsens
13. A phenomenon whereby stimulation to the brainstem causes insensitivity to pain.
17. The experience of discomfort as coming from an area of the body other than where the injury exists.

1. Characteristic ways people behave when they are in pain.

14. Naturally occurring neurochemical whose effects resemble those of the opiates
15. Short term pain that results from tissue damage or other trauma
16. Neurons that connect sensory neurons to motor neurons; association neurons
