Jenny is a little girl whose experience of pain is different from other children her age.She does not have quick reactions to pain that help her avoid painful situations, such as pressing a pin between her fingers or biting down on her hand.However, she is able to feel the prolonged pain from these injuries.Which of the following provides the most likely explanation for Jenny's responsiveness to pain?

A) Jenny's body releases no endorphins.
B) Jenny's fast pathway does not function as well as her slow pathway.
C) Jenny's brain is unable to receive the neural impulses from all pain receptors.
D) Jenny's threshold for pain is low.

Fast Pathway

A term that may refer to a rapid signaling route within the nervous system, especially in the context of pain perception.

Endorphins

Natural chemicals in the body that interact with the brain's receptors to reduce pain and boost pleasure, resulting in a feeling of well-being.

Slow Pathway

A neural transmission route that takes longer due to the involvement of intermediate neurons, often associated with deliberate and considered responses.

  • Identify the function of endorphins and differentiate between the rapid and prolonged pain transmission pathways.

Final Answer :
B
Explanation :
Jenny's slow pathway, which transmits the prolonged pain signals, appears to be functioning normally, while her fast pathway, which transmits quick signals to help her avoid injurious stimuli, is likely impaired. This could explain why she doesn't have quick reactions to painful situations but is still able to feel the prolonged pain.
