PDF-MODULE 24 CENTRAL NERVOUS SYSTEM

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.

Nerves don’t actually touch each other.. Not feeling pain is a good thing.. Most people can get along just fine with out senses.. You can control your nervous system..

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. 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. Figure 1. Nervous System Hierarchy Characteristics of the Central Nervous System The most fundamental way of categorizing groups of neurons that make up the central nervous system is as nuclei and 1. .

One of three meninges that surround and protect the spinal cord and the brain.
