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. Viscous substance between cornea and lens; transparent substance between lens and retina






2. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






3. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






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






5. Hypoglossal Nerve - moves the tongue






6. 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






7. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






8. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






9. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






10. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






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






12. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






13. Portion of a sensory field to which a cell responds






14. Regulates body temperature






15. Has a calcium-related role and produces the hormone parathyroid






16. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






17. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






18. Include tolerance (possible withdrawal) and sensitivity






19. Also known as ABLATION - is any surgically induced brain lesion






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






21. Binding of drug to receptor site that doesn'T interfere with the principal ligand






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






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






24. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






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






26. In the CNS - is an amino acid that stabilizes neural activity






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






28. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






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






30. 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)






31. All have similar molecular structure - so many 'dirty' medications






32. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






33. Transparent substance between lens and retina






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






35. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






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






37. 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






38. The visual image of the world on the retina






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






40. Synchronized EEG activity during its deeper stages






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






42. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






43. The female reproductive cycle of mammals other than primates






44. Norepinephrine and serotonin






45. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






46. Is regulated by the hypothalamus






47. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






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






49. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






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