Describe the preganglionic and postganglionic neurons in the autonomic system. Use a diagram to illustrate the difference in efferent outflow between somatic and autonomic nerves.

Expert Solution & Answer

Summary Introduction

To review:

1. The preganglionic and postganglionic neurons in the autonomic system.

2. The difference in efferent outflow between somatic and autonomic nerves with the help of a diagram.

Introduction:

Autonomic nervous system is associated with the control of involuntary organs and tissues within the body. The activity of the cardiac muscle, glands as well as smooth muscles is regulated by the activity of the autonomic motor nerve. There is involvement of two neurons in the efferent pathway of the autonomic neurons.

Explanation of Solution

The efferent pathway for the conduction of nerve impulse in the autonomic system includes two nerve cells. The first neuron has its own cell body, which is present in the grey matter of the brain or the spinal cord. This neuron is referred to as the preganglionic neuron. The axon of the preganglionic neurons does not innervate with the associated organ but synapses with another autonomic neuron.

The preganglionic neuron synapses with the postganglionic neuron in order to complete the neural pathway. The axon of the postganglionic neuron synapses to the associated effector organ. There is a difference between the efferent outflow of the somatic and autonomic neurons. The somatic neurons synapse directly with their target organs whereas there is involvement of two neurons in the efferent outflow in the autonomic neurons. The difference between the efferent outflow of the somatic and autonomic neuron is shown below:

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
