|
Term
|
Definition
An unpleasant sensory and emotional experience that indicates potential or actual tissue injury.
Pain is highly subjective, multidimensional, and individualized. |
|
|
Term
| The pain experience depends upon what 2 things? |
|
Definition
| Sensory stimulation and perception. |
|
|
Term
|
Definition
| Generated by legitimate tissue damage. |
|
|
Term
|
Definition
| Arises from nerve damage or dysfunction in the CNS or periphery. |
|
|
Term
| General Somatosensory Neurons |
|
Definition
| Have branches that spread all over the body. They sense touch, temp, and pain in the periphery. |
|
|
Term
| Special Somatosensory Neurons |
|
Definition
| Found in the joints, muscles, and tendons. They sense position and movement of the body. |
|
|
Term
| Visceral Somatosensory Neurons |
|
Definition
| Located in the organs. They sense fullness, discomfort, and organ pain. |
|
|
Term
|
Definition
Site to spinal cord.
4 Types of Sensation:
1) discriminative touch
2) temp
3) sense of movement in the joints
4) pain |

|
|
Term
|
Definition
| Have the fastest conduction speed. They are myelinated and sense all types of pain, cutaneous pressure, touch, and cold sensation. |
|
|
Term
|
Definition
| Mid speed. They are myelinated and transmit sensory information from cutaneous and subq mechanoreceptors. |
|
|
Term
|
Definition
| Slowest speed. They are unmyelinated and convey warm-hot sense, mech and chem heat, and cold-induced pain. |
|
|
Term
|
Definition
Second order pathway that goes from the spinal cord straight up to the thalamus. It transmits info regarding perception, arousal, and motor control. The pathway crosses in the medulla.
It is composed of 3 neurons.
1) dorsal root ganglion
2) dorsal column
3) Thalamic |
|
|
Term
|
Definition
| The other sensory pathway. It transmits information regarding pain, thermal sensation, crude touch, and pressure. The path crosses in the anterior commissure and synapes with the thalamus and other regulatory centers for the sympathetic nervous system. |
|
|
Term
| When does pain come into ones consciousness? |
|
Definition
| In the third order pathway. The thalamus can roughly localize the pain as crude sense, but it becomes fully acknowledged and localized when it hits the somatosensory cortex. |
|
|
Term
|
Definition
| The ability to localize the origin of a sensation. |
|
|
Term
|
Definition
| The basic somatosensory system. It involves the sensation of pressure, touch, and vibration. |
|
|
Term
|
Definition
| Involves 3 receptors: cold, warm, and pain. They respond rapidly to sudden changes in temp and then adapt over a few minutes. |
|
|
Term
|
Definition
| The ability for a person to sense their limb without the use of sight. Also called proproception. Lesions on the posterior column will interfere with position sense, and the vestibular system plays a key role. |
|
|
Term
|
Definition
| A sub-pathway that involves pain. It provides rapid pain transmission. The pain is typically sensed as sharp or stabbing in nature. It provides precise sensation of the location of the pain. |
|
|
Term
| Paleospinalthalamic Tract |
|
Definition
| A sub-pathway for pain. It is a slow conduction tract that transmits sensory info that doesnt need to be localized or discriminated against gradual increases of intensity. Stimuli is interpreted as diffuse, dull, aching pain that is typically associated with chronic or visceral pain. Pain in this pathway is associated with the mood-altering, attention-narrowing effects of pain. |
|
|
Term
|
Definition
| The Periacqueductal gray region of the brain. Electrostimulation of this area has been found to develop an analgesic effect that was specific and did not affect the pt's level of consciousness or ability to react to verbal/visual stimuli. This area is called the endogenous analgesia center. |
|
|
Term
|
Definition
| Unpleasant hypersensitivity to pain. |
|
|
Term
|
Definition
|
|
Term
|
Definition
| Reduced tactile sensation. |
|
|
Term
|
Definition
| Absent tactile sensation. |
|
|
Term
|
Definition
| The absence of pain or the reduction of pain without an alteration in the level of consciousness. |
|
|
Term
|
Definition
| Spontaneous, unpleasant sensations. Typically involving a pins and needles sensation. |
|
|
Term
|
Definition
| Characterized by an increased pain threshold, but, when reached, can cause prolonged pain if the stimulus is constant. |
|
|
Term
|
Definition
| Pain is perceived by a non-painful stimulus. Ex- the wind blows and causes someone to feel pain all over the affected area. |
|
|
Term
|
Definition
| A chemical or physical disturbance in the cells or tissue fluids produced by a change. |
|
|
Term
|
Definition
| Psychological changes that are produced by the experience of any life changing events. |
|
|
Term
|
Definition
| Stress that is caused by one's environment. |
|
|
Term
|
Definition
| The stronger the signal is, the more your body will try to dampen it in order to return to homeostasis. |
|
|
Term
|
Definition
| Any change in one of the conditions that your body considers as "normal" is met with immediate resistance, physiologically speaking. This is to maintain homeostasis. |
|
|
Term
|
Definition
| The pt will experience flashbacks during their waking hours or nightmares in which they relive the traumatic event in horrid detail. |
|
|
Term
|
Definition
| This refers to the emotional numbing that the pt experiences which disrupts the pt's personal relationships. |
|
|
Term
|
Definition
| This is a sign/symptom that can be seen through various maladaptive behaviors (such as increased irritability, sleep disturbances, exaggerated startle reflex, etc) in PTSD pts. |
