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. Expression of traits






2. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






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






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






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






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






7. Sleepwalking - sleep talking






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






9. Maintains balance/posture and coordinates body movements






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






11. 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






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






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






14. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






16. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






17. Pass the easiest through the blood-brain barrier






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






19. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






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






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






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






23. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






24. Vestibulocochlear Nerve - hearing and balance






25. 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






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






27. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






28. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






29. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






30. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






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






32. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






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. Oculomotor Nerve - moves eye pupil






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






36. Abducens Nerve - moves eye






37. An area that combines input from diverse brain regions






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






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






40. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






41. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






42. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






43. 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)






44. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






45. Is everything anterior to the central sulcus






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






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






48. Is found between the dura mater and arachnoid mater meninges






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






50. Transparent substance between lens and retina
