The document summarizes the nervous system and chemical coordination system in three parts: 1. The central nervous system includes the brain and spinal cord. The brain is made up of the forebrain, midbrain, and hindbrain. The spinal cord runs through the vertebral column and contains grey and white matter. 2. The peripheral nervous system includes ganglia and nerves that connect the central nervous system to other parts of the body. There are motor and sensory neurons that carry signals between the central nervous system and other body systems. 3. The chemical coordination system includes the endocrine system made up of endocrine glands that secrete hormones to regulate processes like growth, metabolism, and reproduction.
