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. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






2. Regulates body temperature






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






4. Transparent substance between lens and retina






5. Opening in the iris; dilates and contracts allowing different levels of light in






6. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






7. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






8. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






9. Accessory Nerve - moves the head






10. Vagus Nerve - heart rate and digestion






11. Trochlear Nerve - moves eye






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






13. Decreasing effects of a medication due to repeated administration






14. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






15. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






16. Include tolerance (possible withdrawal) and sensitivity






17. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






18. Controls sexual activity






19. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






20. The maintenance of water balance in the body






21. Hypoglossal Nerve - moves the tongue






22. Is everything anterior to the central sulcus






23. Functions as both a hormone and a neurotransmitter in the brain






24. Most brain communications are with the opposite side of the body






25. Increasing effects/effectiveness of a medication due to repeated administration






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






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






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






29. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






30. 'Roof'






31. 'little brain'






32. Maintains balance/posture and coordinates body movements






33. 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






34. Two different presynaptic neurons/inputs to a post-synaptic cell






35. Found in the ventricles and spinal canal






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






37. Moving forward






38. Oculomotor Nerve - moves eye pupil






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






40. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






41. The viscous substance between cornea and lens






42. Norepinephrine and serotonin






43. The increase in REM sleep seen after a period of REM sleep deprivation






44. Is characteristic of indirect antagonists






45. Holds the lens in place






46. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






47. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






48. Is found in the interior rostral temporal lobe - part of limbic system






49. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






50. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia
