identify the anatomy/physiology involved as related to the Nervous System, what is going wrong or has occurred, and how that impacts the Nervous System specifically. provide an explanation for how the Nervous System responds to the situation. A) John is sitting in his living room eating a nice meatloaf dinner and watching the WNBA, when a giant tree crashes down outside. John quickly turns his head to the right, where the noise came from and springs to his feet. John began to sweat and his respiratory rate quickly increased. (hint: besides the excitement, he had to hear this tree first) B) Sandra loves her grandmas blackberry pies, so today she got on her bike and rode down the 3 miles down the road to see if Grandma was baking. About 150 yards from the house, Sandra stopped her bike and took in a deep breath. The smell of fresh baked goods and blackberries hung in the air. Sandra's mouth began to water as she sprinted towards the house. C) Alexis has recently noticed a decline in her coordination and ability to complete normal muscular movements (motor). At times she struggles to hold her coffee mug and other times her legs do not seem as strong or as coordinated as they used to be. At first Alexis, thought it was nothing, but she decided to go to her doctor where they found that the material her Schwann cells make is being broken down by her own immune system, which is causing a loss of somatic motor control. D) Sarah recently has had bouts of increased heart rate of 200bpm and has had to resort to vagal maneuvers to reset the heart rate. Please explain at the nerve and neuron level how a vagal maneuver resets the heart rate, include neurotransmitters, etc.
