  1. 4. neurons that carry outgoing information from the brain and spinal cord to the muscles and glands
  2. 8. neurons that carry incoming information from the body's tissues and sensory receptors to the brain and spinal cord
  3. 10. a pair of endocrine glands that suggest about the kidneys and secrete hormones that help arouse the body in times of stress
  4. 11. the bodies "slow" chemical communication system; a set of glands that secrete hormones into the bloodstream
  5. 13. the body's speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems
  6. 14. the division of peripheral nervous system that controls the body's skeletal muscles
  7. 15. bundled axons that form neural cables connecting the CNS with muscles, glands, and sense organs

  1. 1. the endocrine system is most influential gland. Under the influence of the hypothalamus, this regulates growth and controls other endocrine glands
  2. 2. Chemical messengers that are manufactured by the endocrine glands, travel through the bloodstream, and affect other tissues
  3. 3. the division of the autonomic nervous system that arouses the body, mobilizing its energy
  4. 5. the brain and spinal cord
  5. 6. neurons within the brain and spinal cord; they communicate internally and process information between sensory inputs and motor outputs
  6. 7. the sensory and motor neurons that connect the CNS to the rest of the body
  7. 8. the part of the peripheral nervous system that controls the glands and muscles of the internal organs. Its sympathetic division arouses; its parasympathetic division calms
  8. 9. the division of the autonomic nervous system that calms the body, conserving its energy
  9. 12. a simple, automatic response to a sensory stimulus, such as knee-jerk response
