|
chronic pain from injury of the nervous system
|
|
|

|
point at which pain is felt
|
|
|
Pain pathway
|
Noxisou stimuli > afferent fibers > SC/brain > reflex OR Cerebral cortex > sensory processing
|
|
|
Pain: Sensory-Discriminative
|
site of origin and stimulis > pain
|

|
|
Stress categories
|
Physcial, Physiologic, Emotional (neuroendocrine, autonomic, mental)
|
|
|
3 phases of stress

|
|
|
Euthanasia MUST consider before doing

|
|
|
3 Mechanisms of Euthanasia
