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