Introduction Welcome to the Testing the Nervous System Assignment. This assignment will cover the brain and spinal cord. For this assignment, you will investigate a case and answer the corresponding questions. Remember to view the assignment rubric (see below) before completing the assignment. Case Study The case is based on a case from the National Center for Case Study Teaching in Science and modified/rewritten by Dr. Bruce Forciea. Dr. Mary Smith and Dr. Ashley Peters were beginning their ER residency at ACME Memorial Hospital. They had been close friends throughout medical school and were looking forward to helping each other through the challenges of clinical work. They had just completed a 16-hour shift and were sitting down to enjoy a cup of bitter vending machine coffee when nurse Cassidy burst into the break room.

The "nerve gas," sarin, is a potent, irreversible organophosphate. Based on what you now know about organophosphates, what is the likely cause of death resulting from exposure to this extremely toxic agent? Explain.

Several researchers obtained maximum stress generated by our muscles. Why these values differ from one study to another? And what is the importance of these values?

3. With regards to Vestibular Nystagmus (review nystagmus caused by the inner ear's vestibule due to Meniere's disease), how would you manage a patient with this disorder based on the health clinician profession you have chosen as your career here at Rasmussen University. Again, based on your chosen profession what physical assessments, actions and considerations would you have to perform during your care of a patient with Vestibular Nystagmus? Remember to find and utilize sources pertaining to your chosen profession such as:

Case Study Questions Explain how the appearance of a malignant melanoma differs from that of a normal mole, or nevis, on gross inspection and why it was important to surgically excise and examine this mole. Describe the differences in stages I through IV in melanoma and why it is useful to determine the level of invasion of this lesion. Describe the layer of the integument involved in malignant melanoma and to which tissues of the body the cancer could spread. Why does Hannah's physician think that her cancer has already metastasized?

Introduction "She's awake, Jane's awake," exclaimed Jane's mother as her older brother Cliff and sister Rachelle gathered around the hospital bed. Jane let out a long moan then mumbled a barely audible "what happened?" "Don't try to speak," said Cliff. Just rest for now. "You are going to be all right." Dr. Joel entered the room. "That's great she's awake. It was a bit touchy for a moment there, but I think she will improve quickly. She lost a lot of blood and went into shock. Read the case study. Investigate how Jane's physiology would respond to the blood loss and shock.

1) Compare the benefits and disadvantages of pre- and post-natal surgical interventions? (6marks) Provide a conclusion on which of these surgical interventions you would agree to if the affected child was your own? (4 marks)

What type(s) of autonomic nervous system medications could potentially be used to treat her? Options: adrenergic agonist, adrenergic antagonist, cholinergic agonist, cholinergic antagonist. Explain your answer. (You don't need the internet or your textbook to answer this question.)

3) Diagram and label the histological zones of development of an epiphyseal plate and include a) developmental zones, b) perichondrium, c) periosteum, and d) an endochondral ossification flow chart. Make TWO VERSIONS (or more) and turn in your best and final version.

On the lines provided, write the number of chromosome pairs for each step of meiosis shown in each cell the diagram. Then, answer the questions. 9. How is meiosis important to the study of genetics? 10. How do cells formed by meiosis differ from those formed by mitosis? 11. How does the number of cells produced by meiosis compare to the number of cells produced by mitosis?
