Across
  1. 2. The long part of a neuron by which the cell sends information
  2. 5. A portion of the brain involved in creating and filing new memories.
  3. 7. The study of how environmental factors like diet, stress and post-natal care can change gene expression
  4. 10. The boundary separating the inside contents of a cell from its surrounding environment.
  5. 12. Is involved in attention, emotional responses, and many other functions.
  6. 14. The brain’s “fear hub,”
  7. 15. A change in the code for a gene, which may be harmless or even helpful, but sometimes give rise to disabilities or diseases.
  8. 16. A structure within a cell that contains DNA and information the cell needs for growing, staying alive, and making new neurons.
  9. 18. The substance filling a cell, containing all the chemicals and parts needed for the cell to work properly.
  10. 19. neurotransmitter that regulates many functions, including mood, appetite, and sleep.
  11. 20. nerve cell that is the basic, working unit of the brain and nervous system,
  12. 21. Transmission of signal from the cell body to the synaptic terminal at the end of the cell’s axon.
  13. 23. point of contact for receiving impulses on a neuron, branching off from the cell body.
  14. 24. A chemical produced by neurons that carries messages to other neurons.
Down
  1. 1. neurotransmitter involved in controlling movement, managing the release of hormones, and aiding the flow of information
  2. 3. An electrical communication signal sent between neurons by which neurons communicate with each other.
  3. 4. most common neurotransmitter in a person’s body, which increases neuronal activity,
  4. 6. highly developed area at the front of the brain that, in humans, plays a role in executive functions
  5. 8. A segment of DNA that codes to make proteins and other important body chemicals.
  6. 9. axis A brain-body circuit which plays a critical role in the body’s response to stress.
  7. 10. Contains the nucleus and cytoplasm of a cell.
  8. 11. The “recipe of life,”
  9. 13. imaging technique that uses magnetic fields to take pictures of the brain’s structure.
  10. 17. tiny gap between neurons, where nerve impulses are sent from one neuron to another.
  11. 22. network of neurons and their interconnections.
