- - - - A-delta fibers
        
        small, myelinated
        ~ faster speed of transmission
        
        transmit info about mechanical and thermal pain = sharp, brief
        
        projects on thalamus, sensory areas of cerebral cortex = influence sensory aspects of pain
      - C-fibers
        
        unmyelinated
        
        transmit info about polymodal pain = dull, aching
        
        projects onto (hypo)thalamic and cortical areas = influences affective and motivational aspects of pain
- - - - Chronic benign pain
        
        relatively unresponsive to treatment
        
        pain varies in severity
        e.g. chronic lower back pain
      - Recurrent acute pain
        
        intermittent episodes of pain, acute but chronic
        e.g. migraines
      - Chronic progressive pain
        
        severity increases overtime
        
        associated with malignancies/ degenerative disorders
        e.g. cancer
