PPT-ORGANIZATION OF NERVOUS SYSTEM

DR ZAHOOR ALI SHAIKH LECTURE 1 1 First We Will Discuss ORGANIZATION amp CELLS OF NERVOUS SYSTEM then we will talk about Overview of Central nervous system CNS 2 ORGANIZATION OF NERVOUS SYSTEM. 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. 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. 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 works by sending electrical impulses along neurones (nerve cells).. The Nervous System. There are two main parts:. Central nervous system. – brain and spinal cord. A network of nerves. 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. 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 . 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. The parts of central nervous system. The parts of brain. Neuron. is defined as the structural and functional unit of the nervous system. It is otherwise called nerve cell. Neuron is like any other cell in the body having nucleus and all the organelles in the cytoplasm. However, it is different from other cells by two ways: . is the main component of the two parts of the . nervous system. ; the . brain. and . spinal cord. of the . central nervous system. (CNS), and the branching peripheral nerves of the . peripheral nervous system. THE AUTONOMIC NERVOUS SYSTEM. The autonomic nervous system (ANS) is a motor or efferent system which connects the central nervous system with all smooth muscle, cardiac muscle and gland cells of the body.. 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.
