Summary Introduction

To describe: The basic sequence of events taking place at the neuromuscular junction.

Introduction: The nervous system controls the skeletal muscle fiber contraction. It controls the muscle fiber at the neuromuscular junction (NMJ), which is a specialized intracellular connection situated midway along the length of the muscle fiber.

Expert Solution & Answer

Explanation of Solution

The sequence of events taking place at a neuromuscular junction:

  • The motor neuron presents at the neuromuscular junction’s release acetylcholine (ACh) that alters the permeability of the plasma membrane.
  • This change permits the entry of positive charges. This in turn generates an action potential or electrical impulse in the sarcolemma.
  • The action potential or electrical impulse spreads across the muscle fiber’s surface and also into the interior along the transverse or T tubules.
  • The calcium ion (which are released from the sarcoplasmic reticulum) concentration in the cytoplasm increases, which in turns triggers the muscle fiber contraction.
  • The acetylcholinesterase (AChE) removes the ACh from motor end plate and synaptic cleft and as a result, the contraction ends.

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
