Study Notes
Pain Types
- Nociceptive pain serves as a warning of dysfunction and leads to protective behavioral changes.
- Pathological pain does not serve a biological function and imposes severe detrimental stress.
Cancer Pain
- Cancer pain can be the result of primary tumor growth, metastatic disease, or adverse effects of chemotherapy and radiation treatment.
Neuropathic Pain
- Neuropathic pain originates from injury or post-injury damage to the central or peripheral nervous systems and is possibly associated with motor, sensory, or autonomic deficits.
Transduction
- Transduction is the process of converting stimuli into an action potential or nerve signal at the level of specialized receptors or free nerve endings.
Nerve Fibers
- A-delta fibers transmit immediate sharp pain due to their small diameter and thin myelin sheath.
Modulation
- Modulation is the process of augmenting or suppressing nociceptive information.
Neuroanatomy
- A-delta and C-fibers mainly terminate in the spinal cord's dorsal horn.
Central Sensitization
- Central sensitization refers to the neuroanatomic changes that result in heightened or exaggerated pain states.
Opioid Efficacy
- The efficacy of opioids is especially limited in exaggerated pain states due to central sensitization.
