Pain affects movement through multiple mechanisms. You see a 29 year old healthy young man who had a sudden onset of acute low back pain ~24 hours ago. Which of the following may NOT be a possible mechanism that may affect the control of spinal movements? A.pain-induced inhibition of the back extensor and flexor muscles. B.pain-induced spasm of back extensors C.pain-induced neuroplastic changes in the prefrontal and insular regions that may lead to neuropathic pain. D.abnormal activation of spinal and paraspinal muscles due to arthogenic muscle response

Step 1
Pain-induced inhibition of the back extensor and flexor muscles: This is a possible mechanism, as pain can lead to muscle inhibition and affect movement. B. Pain-induced spasm of back extensors: This is also a possible mechanism, as pain can cause muscle spasms, Show more…

Suppose you were walking barefoot and stepped on a prickly sandbur. Describe the pathway of information, starting with the pain receptor in your foot; that would allow you to both feel and respond to this unwelcome stimulus: (use the above picture as an aid)_

Joe accidentally touched a hot pan. His arm jerked back, and an instant later, he felt a burning pain. How would you explain the fact that his arm moved before he felt the pain? a. His limbic system blocked the pain momentarily, but the important pain signals eventually got through. b. His response was a spinal cord reflex that occurred before the pain signals reached the brain. c. Motor neurons are myelinated; sensory neurons are not. The signals traveled faster to his muscles. d. This scenario is not actually possible. The brain must register pain before a person can react.
