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. An area that combines input from diverse brain regions






2. Important to motor system






3. 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






4. Is used as an anaesthetic for children and animals but causes psychosis in adults






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






6. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






7. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






8. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






9. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






10. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






11. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






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






13. Self-dissolving






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






15. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






16. 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






17. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






18. A single - unfertilized cell created during conception; the combined egg + sperm






19. Is everything anterior to the central sulcus






20. Measure changes in the electrical resistance of the skin (sweat gland activity)






21. Decreasing effects of a medication due to repeated administration






22. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






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






24. The visual image of the world on the retina






25. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






26. Are found in the diencephalon






27. Sleepwalking - sleep talking






28. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






29. Caudate nucleus and putamen






30. Absolute; relative






31. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






32. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






33. Is an oversensitivity to dopamine (D2)






34. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






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






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






37. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






38. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






39. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






40. Sign






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






42. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






43. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






44. Glossopharyngeal Nerve - taste swallow






45. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






46. Midbrain - medulla and the pons






47. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






48. Is regulated by the hypothalamus






49. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






50. 'Roof'
