Yоu must аnswer 1 questiоn (yоu choose) (5 points). In your аnswer, pleаse state which question you are answering (copy and paste the question if possible). Take your time to answer the question. Make sure you read all parts to ensure you do not lose points. Use the test to guide you. Describe how action potentials are generated and propagated along myelinated neurons. As you explain, include these terms – ligand, voltage gates, calcium, sodium, potassium ions, graded potential, threshold, summation, hillock, end bulbs, depolarization, hyperpolarization and repolarization. A 30-year-old female has had several neurological episodes, each separated by several months, in which she experiences brief periods of physical weakness, clumsiness of the legs and hands, visual disturbances, and mood swings. She was experiencing depression, irritability, apathy, or anger more often. She felt her mental ability was declining. She also described uncontrolled movements of her hands, feet, face, and trunk. Recently she had begun to experience short periods of akinesia, or loss of movement. CT scans show evidence of multiple lesions in the white matter of the brain and spinal cord. During her last episode, there were increasing neurological deficits due to an increasing number of disseminated lesions.A) Describe how nerve impulses are transmitted from neuron to neuron (neuronal communication at a synapse). (3pts)B) What is myelin? What is its function? (1pt)C) How are nerve cells covered with myelin in the CNS? In the PNS? (1pt) Explain the difference between continuous propagation and salutatory prorogation. (3pts) Which one occurs on interneurons (1pt)? Why (1pt)? . Describe the functional and structural classifications of neurons (3pts). Are unipolar neurons in a tissue sample of the PNS going to be motor or sensory?(.5) Why?(.5) Are interneurons going to be myelinated? (.5) Why?(.5) Explain in detail the events occurring in the picture at the defined steps. What are the steps called, what gates are involved, what ions are involved, where does it occur on the neuron? (each step is 1 pt). Explain Step 1, 2, 3, 4,5
