The nervous system, due to its complexity and importance, is our novel for this journey! Don’t be dismayed by its length because Chapter 10 , “The Endocrine System,” the related control system, will be a “short story” by comparison.
So far on our journey, we have seen infrastructure, the building blocks and support systems of the city. Soon we will visit transportation, protection, and energy delivery systems. Like any efficient city, the body must have a control system, a system to monitor conditions, take corrective action when necessary, and keep everything running smoothly. Imagine what would happen if a traffic light network in a city suddenly failed. The control systems of the body are the nervous and endocrine systems, which receive help from your various senses. Like any control system, they have a large, complex job that is sometimes difficult to understand. They must keep track of everything that is happening in the body.
Therefore, the nervous and endocrine systems are perhaps the most complex and vital systems we will visit. In this chapter, we start at the bottom of the control hierarchy, with the cells and the spinal cord. Then we focus on the higher-level control at 1694489 – Pearson Education Limited © the brain, and finally we pull everything together to see how all the pieces of the puzzle form the big picture. Learning Outcomes Upon completion of your journey through this chapter, you will be able to: List and describe the components and basic operation of the nervous system. Contrast the central and peripheral nervous systems. Define the parts and functions of nervous tissue. Discuss the anatomy and physiology of the spinal cord. Organize the hierarchy of the nervous system. Locate and define the external and internal structures of the brain and their corresponding functions. Describe the sensory and motor functions of the brain
