Decreased Muscle Tone or Spasm in Response to Heat Is

question 15

Multiple Choice

Decreased muscle tone or spasm in response to heat is primarily caused by

• A) Increased rate of firing of type II efferents, resulting in relaxation response
• B) Decreased rate of firing of type Ib efferents, resulting in decreased production of neurotransmitters at the neuromuscular junction
• C) Increased golgi tendon organ (GTO) activity, resulting in decreased stretch on muscle spindle
• D) Decreased gamma efferent activity, resulting in decreased muscle spindle activity
