Show Answers:

  1. dentrites
    rootlike structures attacted to cell body that RECIEVE impulses
  2. axon
    part of the neurostransmitter that TRANSMITS impulses
  3. action potential
    impulse that provides the basis for conduction
  4. Reuptake
    loose neurotransies sucked up into the axon terminal from the synaptic gap
  5. synapse
    • consists of:
    • axon terminal
    • dentrite
    • gap in between the two
  6. serotonin
    involved in behavioral patterns that involve depression and anxiety
  7. ACh
    • causes muscle contraction
    • and involved in memory formation
    • connected with onset of alzheimers disease
  8. ***Botlin—poison that blocks AcH release causing
  9. GABA
    inhibitory neurotransmitter that may lessen anxiety
  10. dopamine
    • plays role in:
    • movement
    • learning
    • attention
    • memory
    • emotional response
    • linked to Parkinsons (low levels of dopamine=tremors)
    • schizophrenia=overutalize dopamine
  11. endorphins
    inhibit pain by locking pain-causing chemicals out of the receptor sites (aspirin of the neurotransmitters)
  12. Norepinephrine
    accelerates heart rate, affects eating, linked to activity levels and learning

    imbalances linked with mood disorders like depression and bipolar
  13. epinephrine
    hormone that does pretty much the same thing as norepinephrine
  14. Cerebellum
    • muscle control
    • balance
  15. Hippocampus
    • retrieves memories (damage to hippocampus causes victim to be only able to retrieve old memories--not create new ones. 50 first date brains)
    • emotional responses
    • part of the limbic system
  16. Amyglada
    • rage response
    • source of prejudice?
  17. Thalamus
    relay station for senory information. sends info to the cerebral cortex (part of the cerebrum where all the higher level thinking takes place)
  18. Corpus Callosum
    connects the hemispheres of the cerebrum
  19. cerebral cortex
    • wrinkled surface of the cerebrum. where all that matter junk is.
    • sensations and responses
    • divided into frontal, parietal, temporal,occipital lobes
  20. pituatary gland
    gland that secretes prolactin and antideurectic hormone
  21. thyroid
    regulates metabolism
  22. frontal lobe
    • prefrontal cortex
    • executive center
    • home of the motor cortex
    • where we make plans and decisions
    • taps into any sensory to manipulate and make use of
  23. hypothalamus
    • secretes hormones that stimulate pituatary gland
    • basic drives--sex, hunger, agression
  24. rigtht hemisphere
    • Awareness of my true identical self, what you
    • look like is on the right
    • superior in visual-spacial functions
    • recognition, discrimination, emotioanl response, more literal
  25. left hemisphere
    • Perception Skills
    • Language (left brain)
    • Sense of Self (left brain)
    • self awareness and consciousness
  26. brainstem
    regulates heart rate, blood pressure, respiration autononomic nervous functions
  27. occipital lobes
  28. Broca's area
    controls tongue muscle, throat and other facial muscles that are used in speech
  29. Broca's aphasia
    inability to speak fluintly. Language understood but hard to speak
  30. PET scan
    traces amount of glucose metabolized in the brain to create a picture
  31. MRI scan
    uses changes in blood flow to make an image (more blood=more activity)
  32. Angular gyrus
    semantic processing (language stuff)
  33. behavioral genetics
    focuses on transmission of trits that five rise to behavior
  34. Evolutionary psych
    natural selection and adaptation connect with behavior and mental processes transmission of traits.
  35. split brain surgery
    • -Vogel and bogen speculated that split brain surgery would help with epileptic seizures.
    • -Michael Gazzaniga, did early work with the spilt brain surgery on kitties and monkeys
  36. agonsist molecule
    excites the reception site--mimics the neurotransmitter. easier to recieve neurotransmitters on the site
  37. antagonists
    inhibits reception site from recieving neurotransmitters by occupying the receiving site, hence blocking the neurotransmitter from chillin there
  38. Heritability
    • -“difference among people”
    • -How much of your traits are influenced by heredity?
    • -Only individual differences.
  39. Myelin sheath
    • protects the nerves
    • Multiple sclerosis--Attack the myelin sheath
  40. Adrenaline and nonadrenal
    • adrenal glands
    • Fight or flight
  41. hormones
    Differentthan neurotransmitters since hormones are secreted by glands and neurotransmitters are in the neuron. Can be either a hormone or a neurotransmitter.
