Explain how motor signals travel from the PMC to the extremities and how sensory information travels from the body’s exterior to the brain. You needn’t worry about left and right with the PMC or the PSC.In this assignment, you should mention the following vocabulary: decussation, medulla oblongata, homunculus, receptors, spinal cord, spinal nerves.

You suspect there is a protein in blood that has antimicrobial properties. Design an experiment to isolate the protein and test it’s ability to inhibit bacterial growth. How would you determine if it is an antimicrobial peptide or a member of the complement family?

1. Primary adrenocortical deficiency, called Addison’s disease, is a degenerative disease of the adrenal cortex. With this in mind, explain the following manifestations of this disease.
   1. sodium loss in the urine and increased urine volume

1. name each type of membrane and give an example of where they are found.

Why is autoimmunity sometimes associated with infection and how would you test if it is the cause?

In chapter 20 we covered the immune system, both the innate and adaptive. Choose a pathogen and describe how the body will use both innate and adaptive means to combat this pathogen. Get creative with this, there are so many different viruses, bacteria, and parasites that can make us sick!

Make sure you mention the disease/parasite/ailment that is caused by the pathogen, what the body does to protect itself innately, and how the body adapts to this.

1. explain the roles of the adaptive defenses including B cells, T-cells, antibodies-structure, function, classes.

2. Outline the process of digestion from mouth to anus. Be sure to discuss important structures along the way, enzymes, and process.
