Across
  1. 1. body - contains the nucleus
  2. 4. - involved in the regulation of sleep, mood, attention, and learning. Low levels of serotonin are associated with depression and SIDS.
  3. 6. - chemical substances that are stored in tiny sacs within the terminal buttons and involved in transmitting information across the synaptic gap to the next neuron.
  4. 7. - carries information away from the cell body toward other cells
  5. 8. cells: provide support, nutritional benefits, and other functions and keep neurons running smoothly
  6. 10. cell body
  7. 12. - directs the manufacture of substances that the neuron needs for growth and maintenance
  8. 13. - treelike fibers projecting from the neuron, which receive information and orient it toward the neuron’s cell body.
  9. 15. - tiny spaces between neurons
Down
  1. 2. - natural opiates
  2. 3. sends and receives information
  3. 5. Networks: are interconnected pathways of nerve cells that integrate sensory input and motor output
  4. 9. Terminals - Sends information away from the cell body and toward other neuronsNorepinephrine - Stress stimulates the production of this neurotransmitter. Controls alertness. Too much triggers agitation and jumpiness. Too Little is associated with depression.
  5. 10. Nerves: carry information about the world TO the brain
  6. 11. Nerves: carry information FROM the brain to the rest of the body.
  7. 14. - helps to control voluntary movement and affects sleep, mood, attention, learning, and the ability to recognize opportunities for rewarding experiences in the environment. Low levels are associated with Parkinson’s Disease and ADHD. High levels are associated with schizophrenia.
