(BQ) Part 2 book "Human anatomy" presents the following contents: The nervous system - the spinal cord and spinal nerves, the nervous system - the brain and cranial nerves, the nervous system - autonomic nervous system, the nervous system - general and special senses, the endocrine system, the respiratory system, the lymphoid system,. | The Nervous System The Spinal Cord and Spinal Nerves 368 Introduction 368 Gross Anatomy of the Spinal Cord 368 Spinal Meninges 373 Sectional Anatomy of the Spinal Cord 375 Spinal Nerves 386 Reflexes Student Learning Outcomes After completing this chapter you should be able to do the following 1 Discuss the structure and functions of the spinal cord. 2D Locate the spinal meninges describe their structure and compare and contrast their functions. 3D Discuss the structure and location of gray matter and white matter and compare and contrast the roles of both in processing and relaying sensory and motor information. 4 Identify the regional groups of spinal nerves. 5 Discuss the connective tissue layers associated with a spinal nerve. 6 Describe the various branches of a representative spinal nerve. 7 Define dermatomes and explain their significance. 8 Define nerve plexus and compare and contrast the anatomical organization of the four main spinal nerve plexuses. 9 Identify the spinal nerves originating at the four major nerve plexuses list their major branches and analyze their primary functions. 10 D Describe the structures and steps involved in a neural reflex classify reflexes and differentiate among their structural components. 11 Explain the types of motor responses produced by spinal reflexes. The Nervous System THE CENTRAL NERVOUS SYSTEM CNS CONSISTS of the spinal cord and brain. Despite the fact that the two are anatomically connected the spinal cord and brain show significant degrees of functional independence. The spinal cord is far more than just a highway for information traveling to or from the brain. Although most sensory data is relayed to the brain the spinal cord also integrates and processes information on its own. This chapter describes the anatomy of the spinal cord and examines the integrative activities that occur in this portion of the CNS. Gross Anatomy of the Spinal Cord Figures 14.1 to 14.3 The adult spinal cord Figure 14.1a measures .
