When spinal reflexes involve synapses with interneurons within the spinal cord, what physiological adjustments are made?
 
  A) Coordinate movement and position
  B) Adjust response and recovery
  C) Adjust to upright position
  D) Coordinate balance

Question 2

The nurse is caring for a patient with newly diagnosed multiple sclerosis (MS). The patient asks why MS is called an autoimmune disease. What is the nurse's best response?
 
  A) The body attacks its own cells because it responds to specific self-antigens to produce antibodies.
  B) A result of response to a cell that was invaded by bacteria, leading to antibody production to similar cells.
  C) Production of autoantibodies is a normal process that goes on all the time, but immunosuppression limits B-cell response.
  D) People with multiple sclerosis have a genetic predisposition to destroy autoantibodies.

Answer to Question 1

A
Feedback:
Other spinal reflexes may involve synapses with interneurons within the spinal cord, which adjust movement and response based on information from higher brain centers to coordinate movement and position. Spinal reflexes do not adjust response and recovery, adjust the body to the upright position, or coordinate balance.

Answer to Question 2

A
Feedback:
Autoimmune disease occurs when the body responds to specific self-antigens to produce antibodies or cell-mediated immune responses against its own cells. The actual cause of autoimmune disease is not known, but theories speculate that (1) it could be a result of response to a cell that was invaded by a virus, leading to antibody production to similar cells; (2) production of autoantibodies is a normal process that goes continuously, but in a state of immunosuppression, the suppressor T cells do not suppress autoantibody production; or (3) a genetic predisposition to develop autoantibodies is present.
