Flashcards in Chpt. 7 - Key Terms Deck (30):
Sensitivity to pain
Absence of pain
Central nervous system hypersensitivity
A state, caused by constant nociceptive input from the periphery, in which neurons in the spinal cord become hyperexciteable and sensitive to low-intensity stimuli that would not normally elicit a pain response. Also referred to as windup.
An extreme form of stress that leads to anxiety and suffering
Disorientation that occurs during anesthetic recovery as consciousness returns. May be characterized by vocalization, aggression, thrashing, and locomotor activity.
Of unknown or unidentifiable cause
Relating to movement from place to place
Chemical substances released from damaged cells or inflammatory cells that cause a response (such as increasing the sensitivity of peripheral pain receptors.).
The third step in nociception, in which sensory nerve impulses are amplified or suppressed by other neurons.
The incidence of disease
The death rate
Treatment of pain with analgesics that target two or more types of pain receptors.
Resulting from injury of a nerve
Detection by the nervous system of the potential for or actual tissue injury.
An aversive sensory and emotional experience that elicits protective motor actions, results in learned avoidance, and may modify species-specific behavior.
Any assessment tools used to rate the intensity of pain.
Pain that occurs after tissue injury
The final step of nociception, in which sensory impulses are transmitted to the brain, where they are processed and recognized.
Pain control before and /or after surgery.
The protective sensation of pain that occurs when there is no or minimal tissue injury.
Provision of analgesia before tissue injury, including surgery.
A state of increased sensitivity near a site of tissue injury, in which stimulation with a normally non-noxious stimulus is painful
A state of increased sensitivity distant from a site of tissue injury, in which stimulation with a normally non-noxious stimulus is painful
Pain originating form the musculoskeletal or integumentary system. Subclassified as superficial (i.e., skin) and deep (i.e., joints, muscles, bones).
A transdermal patch is a medicated adhesive patch that is placed on the skin to deliver a specific dose of medication through the skin and into the bloodstream. Often, this promotes healing to an injured area of the body.
The first step in nociception, in which noxious thermal, chemical, or mechanical stimuli are transformed into electrical signals called action potentials.
The second step in nociception, in which sensory impulses are conducted to the spinal cord.
Pain originating from the internal organs.
A decrease in body mass, energy, or vigor often caused by disease.
