Chapter 6: Control and Coordination

Introduction

• Control and coordination are the functions of the nervous system and hormones in our bodies.
• The responses of the nervous system can be classified as reflex action, voluntary action or involuntary action.
• The nervous system uses electrical impulses to transmit messages.
• The nervous system gets information from our sense organs and acts through our muscles.
• Chemical coordination is seen in both plants and animals.
• Hormones produced in one part of an organism move to another part to achieve the desired effect.
• A feedback mechanism regulates the action of the hormones.
