Summary Introduction
Case Summary:
A drug is known to decrease heart rate even after cutting T1-T4 white rami. After cutting the vagus nerve, the drug no longer affects the heart rate. It affects the preganglionic and postganglionic neurons. The effect of the drugs is either inhibitory or excitatory.
Adequate Information:
The Autonomic Nervous System (ANS) controls the unconscious movement of the body. It has two important divisions’ sympathetic and parasympathetic divisions. They are present on the preganglionic neuron of the CNS and autonomic ganglia of the PNS. The sympathetic axons travel through the sympathetic chain ganglia to their target cell. The parasympathetic axons travel from cranial and sacral nerves to the target tissue. These branches of nerves either supply the organ or join nerve plexus.
To determine:
The drugs affect the ANS division. The effect caused by the drugs on the synapse between preganglionic and postganglionic neurons. The drug effect is inhibitory or exhibitory.
Given Information:
The parasympathetic division of the brainstem of medulla oblongata controls the effect of the drugs and get excited. By cutting the vagus nerve the effect of the drug get eliminated because it is no longer acting between the preganglionic and postganglionic synapses

MNNNNNNIN M C B A M D F E H K G 8arrow_forwardThe 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 2arrow_forwardThere is currently a H5N1 cattle outbreak in North America. According to the CDC on Feb 26*: "A multistate outbreak of HPAI A(H5N1) bird flu in dairy cows was first reported on March 25, 2024. This is the first time that these bird flu viruses had been found in cows. In the United States, since 2022, USDA has reported HPAI A(H5N1) virus detections in more than 200 mammals." List and describe two mechanisms that could lead to this H5N1 influenza strain evolving to spread in human: Mechanisms 1: Mechanisms 2: For the mutations to results in a human epidered they would need to change how the virus interacts with the human host.

- You have a bacterial strain with the CMU operon: a) As shown in the image below, the cmu operon encodes a peptide (Pep1), as well as a kinase and regulator corresponding to a two-component system. The cmu operon is activated when Pep 1 is added to the growth media. Pep1 is a peptide that when added extracellularly leads to activation of the Cmu operon. Pep1 cmu-kinase cmu-regulator You also have these genetic components in other strains: b) An alternative sigma factor, with a promoter activated by the cmu-regulator, that control a series of multiple operons that together encode a transformasome (cellular machinery for transformation). c) the gene cl (a repressor). d) the promoter X, which includes a cl binding site (and in the absence of cl is active). e) the gene gp (encoding a green fluorescence protein).
