PPT-Lesson 6.1 Overview of the Nervous System

Chapter 6 The Nervous System Our nervous system has the ability to simultaneously direct multiple functions taking place in in our bodies Two major divisions Central nervous system CNS It directs the activity of the entire nervous system. 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.

Central nervous system comprises the brain and the spinal cord with nervous tissue making up the system. This system is the most intricate system in human body.. The nervous tissue consists of rich network of billions of nerve cells in both the CNS and PNS . 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 Human nervous system two major parts: central nervous system and peripheral nervous system.
