  1. What is a sex linked trait?
    A trait associated with a gene that is only carried by the male or female parent.
  2. Define Psychopharmacology
    The study of the effect of drugs/medication on the mind and behavior
  3. Define Behavioral Medicine
    Field of research and practice that focuses on how people's thoughts and behavior affect their health and disease.
  4. Define Behavioral Genetics
    Refers to the study of the degree to which psychological traits, such as sociability, aggression, and mental abilities are inherited.
  5. Elements of the Somatic Nervous System
    Afferent Neurons - Carry information to the brain

    Efferent Neurons - Carry information from the brain to the body
  6. Afferent Division
    Aka Motor division, Carries info from various sense organs to of the body to the brain for processing. Including eyes, ears, nose, tongue, skin, joints, tendons ect.

    Controls voluntary movement of our body.
  7. Occipital Lobe
    "Visual Cortex"Strongly associated with the processing of visual stimuli received from the eye
  8. Cerebellum
    Involved in coordination of voluntary movements and fine motor control, some learning and memory. Its the first thing to "Get drunk"
  9. The PONS
    Involved in hearing, balance, and some parasympathetic functioning.
  10. Meduella
    Involved in breathing and reflexive activity
  11. The Reticular Formation
    Involved in arousal and alertness
  12. The Thalamus
    Routes incoming sense stimuli to the appropriate parts of the brain and links the upper and lower part of the brain.
  13. Hypothalamus
    Underneath the thalamus. Involved in our motives and emotions. Also, plans a key role in regulation body temp, sleep, blood pressure and heart beat.
  14. Broca's Area
    • Frontal Lobe
    • Involved in generation of language
    • Usually in the located in the left hemisphere
  15. Association Areas
    • Located in frontal lobe
    • non-dedicated area of the brain to process information
  16. Motor Cortex
    • Located in frontal lobe
    • regulates voluntary movement of the body
  17. Somatosensory
    • Located in parietal lobe
    • Involved in our experience of being touched
  18. Wernicke's Area
    • Located in Temporal Lobe
    • Involved in comprehension of language
    • Usually located in left hemisphere
  19. Limbic System
    • Part of the forebrain
    • Contains amygdala, hippocampus, cingulate cortex
    • implicated in emotionality
  20. Amygdala
    • Involved in memory of emotions associated with events
    • Part of the Limbic System
  21. Hippocampus
    • Involved with encoding new memories of events
    • Part of the limbic system
  22. Cingulate Cortex
    • Implicated in cognitive processing of emotion
    • Part of the limbic system
  23. Soma
    Cell body of the neuron
  24. Nucleus
    Located in the soma
  25. Dendrites
    Serve as receptor sites for incoming information
  26. Axon Hillock
    The "firing"of a neuron begins here
  27. Axon
    • Hollow tube extends from soma to terminal branches
    • Has semi-permeable membrane
    • Has iron gates
  28. Terminal Branches
    Branches that permit communication with many other neurons
  29. Myelin Seathing
    • Fatty substance coating some neurons
    • May not develop until after birth
    • Increases the speed of transmission down the neuron
  30. Nodes of Ranvier
    Ion gates located here to permit depolarization to occur
  31. Synaptic Vesicles
    • Small pouches in terminal buds
    • Contain neurotransmitters
    • Attach to cell wall during synaptic transmission
    • Release neurotransmitters into synaptic gap
  32. Neurotransmitters
    Chemical the conveys information from one neuron to the next
  33. How A Neuron Works
    • Stimulation of the dendrites sends a graded potential towards the axon hillock
    • If reaches the absolute threshold the neuron "fires"
    • Once fired the neuron depolarizes and open the ion gates
    • The graded potential "fires" down the neuron towards the terminal branches
    • After the ion gates close an exchange between potassium (in) and sodium (out) is made
    • Once the electric charge reaches the terminal buds its causes the vesicles to attach to the wall and releases neurotransmitters into the synaptic gap
    • The neurotransmitter stimulate the next neuron then is released back where it is either reabsorbed, attacked and broken down or reattach
  34. Where is the language center for most people?
    The temporal lobe in the Wernicke's area
  35. What is saltatory conduction?
    When axons have myelin sheathing is helps the Action potential to jump node to node. "To leap"
  36. What is reuptake?
    Is when a neurotransmitter is reabsorbed by the terminal bud it was released from
  37. What is a MRI?
    Magnetic resonance imaging; Scans using radio waves to get a detailed map of the brains and what parts o the brain is being utilized.
  38. What is aphasia
    It is a language disorder that results in damage to the brain
  39. What is brain plasticity?
    The ability for nerves to change through new experiences
  40. What is the pituitary gland?
    "master gland" as it controls hormone functions such as our temperature, thyroid activity, growth during childhood, urine production, testosterone production in males and ovulation and estrogen production in females ect
  41. Thyroid Gland
    Gland below the voice box that regulates metabolism
  42. Adrenal Glands
    Two glands on the kidneys that are involved in physical and emotional arousal
  43. What neurotransmitter is implicated with schizophrenia?
    Dopamine
  44. What neurotransmitter is associated with Alzheimer's?
    Lack of acetylcholine
  45. Primary vs Secondary motives
    • Primary motives - motives for things that are necessary for survival such as food water and warmth.
    • Secondary motives - achievement, acceptance ect
  46. Leptin
    regulates energy intake and output; acts on the receptors of the hypothalamus that inhibits appetite
  47. Angiotensin
    Causes blood vessels to constrict, and drives blood pressure up
