Myelinated A-delta fibers
Unmyelinated C fibers
Any sensory fiber with a low pain threshold
The reticular formation
The corticospinal tract
The spinothalamic tract
The relevant dermatome
At the synapse by the entry of other sensory impulses
By the stress response
By the administration of morphine directly into the spinal cord
By referring the pain to other parts of the body
Subjective pain response
Depression and debilitation
A perception of increased generalized pain and discomfort
Fatigue and lower pain tolerance
A stress response
Pain receptors that are stimulated by thermal, chemical, or physical means
Spinal nerves that conduct impulses from specific areas of the skin
Responsible for the state of arousal with pain
Useful in localizing pain to a specific area of the body
Pain that is perceived as occurring in an amputated limb
Severe pain that cannot be controlled by medication
Pain perceived as coming from a source other than the actual source
Pain coming from a specific dermatome
The brain is more aware of pain impulses when the reticular activating system is depressed.
Acute pain does not cause a reflex response at the spinal cord synapses.
Young infants respond to pain with tachycardia and increased blood pressure.
Chronic pain is easier to tolerate without negative effects.
Pain caused by inflammation
Pain in young infants
Intravenous general anesthesia
