Match the pain theory to the correct physiologic basis for the pain.
 
  A. Specificity theory
 
  1. Light touch applied to the skin would produce the sensation of touch through low-frequency firing of the receptor.
 
  B. Pattern theory
 
  2. Repeated sweeping of a soft-bristled brush on the skin over or near a painful area may result in pain reduction for several minutes.
 
  C. Gate control theory
 
  3. Proposes that the brain contains a widely distributed neural network that contains somatosensory, limbic, and thalamocortical components.
 
  D. Neuromatrix theory
 
  4. Describes how an acute injury is predicted to be but does not take into account the person's feelings of how the pain feels to him or her.

Question 2

Answer to Question 2

Ans:
B

Feedback:

The etiology of myasthenia gravis involves a deficiency of acetylcholine receptors at neuromuscular junctions. Treatment can include corticosteroid therapy and intravenous immunoglobulins. Destruction of skeletal muscle cells, cerebellar lesions, and excess acetylcholinesteras e are not noted to underlie the disease.
