Gre Psychology: Experimental/natural Science Biology

Subjects : gre, psychology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






2. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






3. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






4. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






5. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






6. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






7. If head is rotated - eye movements occur in the same direction






8. Adenine - Guanine - Thymine - Cytosine






9. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






10. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






11. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






12. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






13. Combines input from diverse brain regions; receives sensory information/sends motor impulses






14. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






15. Is used to treat Parkinson'S Disease






16. Hypoglossal Nerve - moves the tongue






17. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






18. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






19. Sign






20. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






21. Is a peptide neurotransmitter and a natural painkiller and antianxiety






22. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






23. Is characteristic of indirect antagonists






24. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






25. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






26. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






27. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

28. Hormones that reduce pain






29. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






30. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






31. Dorsal part of midbrain; includes the superior and inferior colliculi






32. Hypothalamic-pituitary-adrenal axis -controls stress response






33. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






34. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






35. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






36. Glossopharyngeal Nerve - taste swallow






37. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






38. Is an oversensitivity to dopamine (D2)






39. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






40. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






41. Skin senses that register the sensations of pressure - warmth and cold






42. Caudate nucleus and putamen






43. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






44. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

45. Is increased in its production by training/experience and therefore - associated with memory






46. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






47. The visual image of the world on the retina






48. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






49. Most pervasive excitatory neurotransmitter in the brain






50. Holds the lens in place
