Definition
| Fine nerve fibers that receive pain signals |
|
|
Term
|
Definition
| Activation of the nociceptors (activation of pain) |
|
|
Term
|
Definition
| Symptomatic Pain - Where disease or known condition underlies pain |
|
|
Term
|
Definition
| Nonmalignant pain - pain can be disabling, no disease or degeneration is associated with pain to help identify cause. |
|
|
Term
| Two Principles to help define pain for therapeutic regimen |
|
Definition
1. neurophysiology of pain - significant differences exist in the neurological processing, perception, and impact of acute pain compared with chronic pain.
2. Different approaches to pain management are effective with different types of pain. |
|
|
Term
| Acute Pain Classification |
|
Definition
Underlying cause is transitory
Treatment of pain is symptomatic
Resolution based on underlying cause |
|
|
Term
|
Definition
| To keep body systems in homeostasis. I.E. heart rate, blood pressure, secretion of hormones, glucose levels, gastric secretions, temperature, etc. |
|
|
Term
|
Definition
| Increased sensitivity to pain. Mediated through dorsal horn of the gray matter. |
|
|
Term
|
Definition
| the excitatory neurotransmitter, binds to the NMDA class of glutamate receptors and permits entry of CA2 into the second order neuron. Nitric oxide is activated |
|
|
Term
|
Definition
| unmyelinated fibers in mucous membrane, serous membrane, skin, deep tissue and myocardium. Responsible for dull pain. Action potentials associated with tissue damage or insult. Stimulation produces brandykinin, serotonin, histamine, and potassium in injured tissue. |
|
|
Term
|
Definition
| in mucous and serous membranes, skin. produce sharp pain sensation. They fire upon intense stimulation then cease when stimulation is removed. |
|
|
Term
|
Definition
| The neuron that the A delta and C fibers synapses with neurons in the spinal cord. |
|
|
Term
| Mesencephalic Periaqueductal Gray Matter |
|
Definition
| an area of cells surrounding the cerebral aqueduct in the mid brain. potentials are relayed to the hypothalamus. neurological basis for endocrine, autonomic, and emotional components of pain response. |
|
|
Term
|
Definition
| Cells in the region of the dorsal midbrain associated with responses to visual and auditory stimuli. They promote spinal cord motor mechanisms, enhancing spinal reflexes and facilitating behavioral responses. |
|
|
Term
| Neospinothalamic Pain Pathway |
|
Definition
| A Delta Fibers terminate in the posterior nuclear group in the thalamus. Stimulates the flexor-withdrawal reflex (touching something hot will make you move your hand away, etc) |
|
|
Term
| Paleospinothalmic pain Pathways |
|
Definition
| C fibers...discrimination and localization of pain in this system is imprecise. |
