Ch 4850 Introducingyour best friend the Neuron Neuron basic structural unit Cell body soma contains nucleus amp organelles Dendrite receives stimuli Axon sends nerve impulses. 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. Biol 105. Lecture Packet 10. Chapter 8 . Outline. Central Nervous System vs Peripheral Nervous System. Peripheral Nervous System. Autonomic Nervous Systems. Somatic Nervous Systems. Autonomic Nervous System. NERVOUS SYSTEM. NERVOUS SYSTEMS RECEIVE SENSORY INPUT, INTEPRET IT, AND SENT OUT APPROPRIATE COMMANDS. NERVOUS SYSTEMS. MOST INTRICATELY ORGANIZED DATA PROCESSING SYSTEM ON EARTH. NEURON. FUNCTIONAL UNIT; SPECIALIZED NERVE CELL FOR CARRYING SIGNALS FROM ONE LOCATION IN THE BODY TO ANOTHER. Central Nervous System. Peripheral Nervous System. The Nervous System. Central Nervous System. The Nervous System. Central Nervous System. Central Core. Limbic System. Cerebrum. The Nervous System. Central Nervous System. Structure and Function. 2. Input. (sensation). Output. (action). In order to understand behavior, we must understand the operating mechanism of the nervous system. What is the function of the nervous system?. Mr. E Murphy. Strange fact. A newborn baby's brain grows almost 3 times during the course of its first year. . Objectives. Identify the importance of the nervous system in humans. Know the difference between the CNS and the PNS. Central Nervous System (CNS). Brain and Spinal Cord. Peripheral Nervous System (PNS). All other nervous tissue throughout the body. Central Nervous System (CNS). Nerve Tissue:. White Matter or Gray Matter. 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. The nervous system has 2 major components:. Central Nervous System (CNS). Peripheral Nervous System (PNS).. The CNS. The Central Nervous System includes the brain and the spinal cord. . They are so important to the human body that they are encased in bone for protection.. Section 1 – Functions & Divisions of the Nervous System (pp. 386-387). This is your brain…. The Nervous System. And this is your brain – IN ANATOMY!!. Or better yet…. The Nervous System. Functions 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 = .
