                             Coordination in mammals









           Introduction
             Imagine  a world where  animals cannot  sense danger, move  their  limbs, or
             react  to  their  surroundings.  Survival  would  be  nearly  impossible!  Fortunately,
             animals, including humans, possess systems that enable them to detect changes
             in their environment and respond appropriately. This remarkable ability is made
             possible through coordination, a highly organised network that ensures smooth
             communication between different parts of the body. In this chapter, you will describe
             coordination in animals including nervous coordination in human, structures of
             neurones and sense organs. Competencies developed will enable you understand
             risk behavious that can impaire proper functioning of the nervous system and avoid
             them. This will in turn promote proper functioning of your nervous system.
