MBBS Lecture Dated 28022018 Dr Sanjeev Kumar Mittal Professor amp Head Dept of Ophthalmology All India Institute of Medical Sciences Rishikesh INTRODUCTION 28092018 DrSanjeev Kumar MittalAIIMS Rishikesh. A. Bacterial Infections of the Nervous System. 1. Bacterial Meningitis. A) Although bacteria can infect the brain, spinal cord, and peripheral nerves, they more commonly infect the meninges and cerebrospinal fluids resulting in meningitis. Functions of the Nervous System. Sensory input – gathering information. To monitor changes occurring inside and outside the body. Changes = stimuli. Integration. To process and interpret sensory input and decide if action is needed. Cognitive Neuroscience. David Eagleman. Jonathan . Downar. Chapter Outline. An Overview of the Nervous System. The Peripheral Nervous System. The Spinal Cord. The Brainstem. The Cerebellum. The Diencephalon. Peripheral Nervous System. Autonomic Nervous System. Allied Health I. Central Nervous System. Communication and coordination system of the body. Seat of intellect and reasoning. Consists of the brain, spinal cord, and nerves. The . function of the nervous system is:. To sense, interpret, and respond to internal and external environmental changes to maintain a steady state in the . body (homeostasis). The nervous system is divided into two major structures: . Brain. Spinal Cord. Nerves. Vocabulary to Know . Homeostasis. The regulation of steady, life-maintaining conditions inside an organism, despite changes in its environment . Nerve Cells . Neurons. Basic functioning units of the nervous system . The Nervous System Central Nervous System Peripheral Nervous System Procedure A starting person will be chosen and will be given an object. Once the teacher gives the signal, the start person will pass the object to their right. 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 . Brain. Spinal Cord. (also includes 4 chambers in brain called ventricles). Brain. 1) Cerebral Hemispheres. 2) Diencephalon. 3. ) Brain Stem. 4) Cerebellum. 1) Cerebral Hemispheres. Covered by ridges = . 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. is the main component of the two parts of the . nervous system. ; the . brain. and . spinal cord. of the . central nervous system.
