Across
  1. 3. The minimum stimulation needed to trigger a neural impulse.
  2. 7. The brain’s sensory relay station that directs most sensory information to the appropriate cortex.
  3. 9. A neurotransmitter that helps regulate mood, sleep, and appetite.
  4. 10. Neurons Carry commands from the CNS to muscles and glands.
  5. 11. Controls voluntary movements and carries sensory information to the CNS.
  6. 14. Activates the fight-or-flight response during stress or danger.
  7. 15. The part of the brain responsible for basic survival functions, including breathing and heart rate.
  8. 16. Neurons that connect other neurons and process information within the CNS
  9. 19. A brain structure involved in processing emotions, especially fear and aggression.
  10. 22. All nerves outside the brain and spinal cord that connect the CNS to the rest of the body.
  11. 23. Substances that mimic neurotransmitters or enhance their activity.
  12. 26. A neurotransmitter involved in muscle movement, learning, and memory.
  13. 27. The body’s roughly 24-hour internal clock that regulates the sleep-wake cycle.
  14. 29. A neuron either fires completely when its threshold is reached or does not fire at all.
  15. 30. Neurons Carry information from sensory receptors to the CNS.
  16. 31. Calms the body and restores energy through the rest-and-digest response.
  17. 32. The process by which a sending neuron reabsorbs neurotransmitters from the synapse.
  18. 33. The negative electrical charge inside a neuron when it is not firing.
Down
  1. 1. The brain’s ability to change and reorganize its connections through experience, learning, or injury.
  2. 2. The brain region that coordinates balance, posture, and voluntary movement.
  3. 4. The process of detecting physical stimuli from the environment through sensory receptors.
  4. 5. The part of the nervous system that controls involuntary functions, such as heartbeat and digestion.
  5. 6. Substances that block neurotransmitters or reduce their effects.
  6. 8. Natural chemicals that reduce pain and can produce feelings of pleasure.
  7. 12. The brain’s outer layer responsible for complex thinking, perception, language, and voluntary actions.
  8. 13. Chemical messengers that carry signals between neurons across synapses.
  9. 17. Regulates hunger, thirst, body temperature, and other basic drives; also helps control the endocrine system.
  10. 18. Cells that support, protect, and nourish neurons.
  11. 20. A neurotransmitter involved in reward, motivation, movement, and learning.
  12. 21. The brief period after firing when a neuron resets and cannot fire normally again.
  13. 24. The basic building block of the nervous system that receives and transmits information.
  14. 25. A brain structure essential for forming new explicit memories.
  15. 28. The brain and spinal cord that process information and control the body.
