Chapter 14, Problem 1RAC
Summary Introduction

Introduction:

Nociceptors are the sensory neurons and are located in the deep structures of the body. The signals produced by these receptors in deep body tissues are biologically as well as clinically important.

Answer to Problem 1RAC

The correct answer is option (c) painful mechanical, chemical, or thermal stimuli.

Explanation of Solution

Explanation for the correct answer:

Option (c) painful mechanical, chemical, or thermal stimuli. Nociceptors are the neurons that sense the pain and respond to potentially damaging stimuli. These neurons respond to stimuli by transferring threat signals to the spinal cord and brain. So, the correct answer is option (c).

Explanation for incorrect answer:

Option (a) changes in temperature at the site of the receptor. Nociceptors respond to the extreme alterations in temperature that induce pain. So, this is an incorrect option.

Option (b) compression, bending, or stretching of cells. The compression, stretching of cells, or bending can stimulate the nociceptors. However, the stretching or bending outside a normal range only can cause pain. So, this is an incorrect option.

Option (d) light striking a receptor cell. The light striking a particular receptor cell must be strong enough to induce pain in order to trigger a nociceptor reaction. So, this is an incorrect option.

Conclusion

Nociceptors mainly respond to damaging stimuli such as painful mechanical, thermal, or chemical stimuli. Hence, the correct answer is option (c) painful mechanical, chemical, or thermal stimuli.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?  3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
