Across
  1. 2. cord consisting of nerves that run up and down the length of the body and back and transmit most messages between the body and the brain
  2. 5. chemical substances that carry messages through the body in blood
  3. 7. twins who come from one fertilized egg; twins having the same heredity
  4. 9. set of genes in an organism
  5. 11. the genetic transmission of characteristics from parent to offspring
  6. 13. nervous system compromised of the brain and spinal cord
  7. 14. the long, thin cells of nerve tissue along which messages travel to and from the brain
  8. 18. chemicals released by neurons, which determine the rate at which other neurons fire
  9. 20. gland that is the center of the control of the endocrine system that secretes a large number of hormones
