Across
  1. 3. cells that transmit information throughout the nervous system and are responsible for behavior and mental processes.
  2. 5. An inhibitory neurotransmitter that reduces neural activity and promotes relaxation.
  3. 10. A neurotransmitter involved in reward, motivation, movement, and mood regulation.
  4. 13. A hormone involved in the stress response, increasing heart rate and arousal.
  5. 15. Psychoactive drugs such as marijuana that typically cause distortions in perception and/or cognition.
  6. 16. perspective, A theoretical approach that explores how natural selection affects the expression of behavior and mental processes to increase survival and reproductive success.
  7. 17. nervous system, The division of the autonomic nervous system responsible for the 'rest and digest' response that helps reduce anxiety and promote relaxation.
  8. 18. nervous system, The division of the peripheral nervous system that governs involuntary processes such as heart rate and digestion.
  9. 23. Neurotransmitters involved in pain relief and the experience of pleasure.
  10. 27. nervous system, The part of the nervous system consisting of the brain and spinal cord that processes information and coordinates responses.
  11. 28. Psychoactive drugs such as alcohol that typically decrease neural activity and slow down the central nervous system.
  12. 29. potential, A rapid change in a neuron's membrane potential that allows it to transmit signals over long distances.
  13. 31. nervous system, The division of the autonomic nervous system responsible for the 'fight or flight' response that contributes to feelings of anxiety.
  14. 32. Psychoactive drugs that bind to receptors and discourage neural firing by blocking neurotransmitter effects.
  15. 33. neurons, Neurons that transmit signals from the central nervous system to muscles to produce movement and behavior.
  16. 34. nervous system, The part of the nervous system consisting of the brain and spinal cord that processes information and coordinates responses.
  17. 35. The central organ of the central nervous system that processes information and controls body functions.
  18. 36. Psychoactive drugs that bind to receptors and encourage neural firing by mimicking or enhancing neurotransmitter effects.
  19. 37. transmittion,The process by which neurons communicate through the release and reception of neurotransmitters across synapses.
  20. 38. principle, The rule that a neuron either fires completely or does not fire at all; there is no partial firing of an action potential.
  21. 39. cord, The bundle of nerves extending from the brain through the vertebral column that is part of the central nervous system.
  22. 40. A hormone that increases appetite and signals hunger to the brain, primarily produced in the stomach.
Down
  1. 1. The process by which a neuron's membrane potential becomes less negative, moving toward or past zero, triggering an action potential.
  2. 2. nervous system, The part of the nervous system outside the brain and spinal cord that connects the central nervous system to the rest of the body.
  3. 4. A chemical messenger released into the bloodstream that affects behavior and mental processes similar to neurotransmitters.
  4. 6. studies, A research method that compares adopted children to their biological and adoptive parents to determine the effects of genes and environment on behavior and mental processes.
  5. 7. cells, Cells in the nervous system that provide structure, insulation, communication, and waste transport to support neural function.
  6. 8. studies, A research method that examines similarities in traits and behaviors among family members to determine the effects of heredity and environment.
  7. 9. A compulsive pattern of psychoactive drug use that can create significant withdrawal symptoms when the drug is no longer consumed.
  8. 11. studies, A research method that compares similarities and differences between identical and fraternal twins to determine the effects of genes on behavior and mental processes.
  9. 12. message, A neurotransmitter signal that makes an action potential less likely by hyperpolarizing the receiving neuron.
  10. 14. nervous system, The division of the peripheral nervous system that governs voluntary processes and skeletal muscle control.
  11. 15. Genetic or predisposed characteristics that influence physical, behavioral, and mental traits and processes; also referred to as 'nature.'
  12. 19. An excitatory neurotransmitter involved in learning and memory.
  13. 20. External factors that one experiences, such as family interactions or education; also referred to as 'nurture.'
  14. 21. message, A neurotransmitter signal that makes an action potential more likely by depolarizing the receiving neuron.
  15. 22. A hormone that regulates sleep-wake cycles and circadian rhythms.
  16. 24. selection, The process by which traits that increase survival and reproductive success become more common in a population over time.
  17. 25. A discriminatory application of evolutionary principles that seeks to improve human populations through selective breeding or genetic manipulation.
  18. 26. A hormone that decreases appetite and signals satiety (fullness) to the brain, produced by fat cells.
  19. 30. Neurons in the central nervous system that connect sensory and motor neurons and process information between them.
  20. 36. A neurotransmitter involved in muscle movement, learning, and memory.
