NERVOUS SYSTEM
•Like other systems in the body, the nervous
system is composed of organs, principally the
brain, spinal cord and nerves.
• These, in turn, consist of various tissues,
including nerve, blood, and connective tissue.
•Together these carry out the complex
activities of the nervous system.
•All our activities and sense organs are
controlled by the nervous system.
