The Nervous System Good Morning… Bell Ringer #1: Reflect back over winter break . Bell Ringer #2 Review your notes from last class. Answer the following question using those notes: How did your nervous system help you conduct the activity you did in the computer lab (red light/green light activity)? 1. Two main divisions. a. . Central Nervous System . (CNS) – consists of brain and spinal cord. b. . Peripheral Nervous System . (PNS) – includes nerves extending from . brain and . spinal . cord . DR. ZAHOOR ALI SHAIKH . LECTURE--- 1. 1. First We Will Discuss ‘ORGANIZATION & CELLS OF NERVOUS SYSTEM’ then we will talk about ‘Overview of Central nervous system’ [CNS]. 2. ORGANIZATION OF NERVOUS SYSTEM. History of Research on Nervous system. 460 -379 B.C. . Hippocrates discuss the epilepsy as disturbance of brain and also indicated that the brain is involved with sensation and is seat of intelligence. . A. Central Nervous System (CNS). 1. . Functions . A) . Acts . as command center. B) . Interprets . sensory information and dictates response based on past experience, . reflexes, . and current body conditions. (CNS) AND THE PERIPHERAL NERVOUS SYSTEM (PNS) Learning objectives: The nervous system in humans is a complex integration of organs like brain, spinal cord and sensory organs along with nerves. N Human nervous system two major parts: central nervous system and peripheral nervous system. Nervous System Organization. Brain. Spinal cord. Central Nervous System. Nervous System Organization. All neurons outside the CNS. Persistant viral infections of the central nervous system. Genomes either integrate or persist as episoms. Mechanism of persistance is not yet understood. Avoid detection and elimination by the host. 85 to 180 billion neurons in the human brain?! How does anything get done?. CENTRAL NERVOUS SYSTEM. Brain and spinal cord.. PERIPHERAL NERVOUS SYSTEM (PNS). Def. : all nerves that lie outside the brain and spinal cord. 3.02 Understand the functions and disorders of the nervous system. 3.02 Understand the functions and disorders of the nervous system. 2. 3.02 Essential Questions. What . are . the . functions . of the nervous system?.
