- Neurofibromatosis type 1 is a condition where tumours can grow in the nerves near the skin. The growth of tumours prevents the action potentials from quickly travelling through the neurons. Identify the nerve structure from the image below and the division of the nervous system affected by neurofibromatosis type 1. CNS = Central Nervous System PNS = Peripheral Nervous System Select one: a. Nerve Structure Division of Nervous System 3 PNS b. Nerve Structure Division of Nervous System 4 CNS c. Nerve Structure Division of Nervous System 5 PNS d. Nerve Structure Division of Nervous System 1 CNSMark the following statements as true of false. If a statement is false, correct it to make a true statement. a. Ependymal cells regulate the composition and movement of cerebrospinal fluid. b. Schwann cells make myelin in the peripheral nervous system c. Microglia are neuroglial cells with an immune function. d. Oligodendrocytes repair damaged axons in the peripheral nervous system. e. Astrocytes regulate the extracellular environment of the brain and are key components of the blood-brain barrier. f. Oligodendrocytes and Schwann cells perform similar functions in different parts of the nervous system.Imagine that you're hiking in the mountains one afternoon with friends. As you turn to the corner, you come across a mother bear and her cubs standing in the middle of the trail. A. Identify the specific division of the nervous system that is responsible that is responsible for the body's response to this situation. Explain B. Describe at least four physiological responses you might have upon seeing the bears. C. Indicate the division of the nervous system that is responsible for returning the body back to equilibrium after the event is over Explain
- Currently, the medication that manages the symptoms of Alzheimer's disease is a type of cholinesterase inhibitor. In other words, the medication inhibits the function of cholinesterase and helps in brain functioning and memory. a. What is the function of cholinesterase in the synapse? b. How does a cholinesterase inhibitor work in a synapse? c. Explain how cholinesterase inhibitors are able to increase brain functioning and memory.This assignment is designed to get you thinking about the functions of some of the structures in the central and peripheral nervous system. Listed below are different symptoms or complications that can be attributed to something from the nervous system. List the specific structure that is most likely the root cause of the pathology. In addition, label which branch of the nervous system that structure is a part of (CNS or PNS). I suggest making a table with the pathology in one column, the affected structure in the next column, and the nervous system section in the final column. Two examples are below. It is possible that more than one answer could be correct. Pathology/Patient Specific Structure CNS or PNS? John’s eyes and optic nerve are in optimal condition, but he is still classified as legally blind. Primary Visual Cortex CNS Although Meredith is the CEO of Yankee Candle, she cannot smell a thing.

- Alzheimer’s disease is thought to cause a DECREASE in the amount of acetylcholine (ACH) being released into the synaptic cleft in specific parts of the brain. What would be a possible treatment for this disease? (So basically- what would be a possible way to increase the amount of ACH in the synaptic cleft?)Multiple sclerosis is a demyelinating disease, in which the patient’s immune system attacks and destroys the cells that form the myelin sheath in the central nervous system. Which cell would be responsible? Would Schwann cells or oligodendrocytes, both or none of them be affected? a. Schwann cell b. Oligodendrocytes c. Both Schwann cells and Oligodendrocytes d. None of the aboveWhat do multiple sclerosis and ALS (amyotropic lateral sclerosis) have in common?a. They both are more common in young men than in young women.b. They both impair the initiation of action potentials.c. They both damage the myelin sheath, disrupting action potential transmission.d. They both impair nerve function in the peripheral nervous system
- A neurotransmitter is a chemical messenger that carries, boosts, and balances signals between neurons, nerve cells, and other cells in the body. a) Identify two disorders that can result in a depletion, damage, or lack of neurotransmitters in our body. Then list and explain at least two neurotransmitters that can result in these disorders developing.Explain in detail with the most information necessary to demonstrate your understanding of how schizophrenia disease is affected by the nervous system. (An explanation of more than 800 words)~Multiple Sclerosis (MS) Multiple sclerosis is a neurodegenerative disease in which the body's immune system attacks and breaks down the white matter in the nervous system. 1. What is another word (other than "white matter") for the structure or type of cells that are affected in patients with MS? 2. Given what these cells/ structures do, what effect on neural transmission do you think MS has? ~ Some common symptoms of MS are vision problems, dizziness and vertigo, and difficulty walking. 1. How are these symptoms a result of the effect on neural transmission you described above? 2. List which brain regions are likely impacted in each of the three symptoms described above.
