• Nociception — the neural process of detecting potentially harmful stimuli
• Acute Pain — pain as protective signal, proportionate to tissue threat
• Chronic Pain — pain persisting beyond tissue healing, driven by nervous system changes
• Central Sensitization — amplification of neural signaling within the central nervous system
• Allodynia — pain from stimuli that are not normally painful
• Hyperalgesia — increased pain from stimuli that are normally painful
