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. 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






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






3. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






4. Caudate nucleus and putamen






5. 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)






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






7. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






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






9. 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






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






11. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






12. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






13. Produce drowsiness and sleepiness






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






15. Referred to as the satiety center; lesions lead to obesity and hyperphagia






16. Facial Nerve - moves face and salivates






17. 'covering'






18. 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






19. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






20. Important to motor system






21. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






22. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






23. Pass the easiest through the blood-brain barrier






24. Regulates body temperature






25. Found in the ventricles and spinal canal






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






27. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






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






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






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






31. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






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






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






34. Glossopharyngeal Nerve - taste swallow






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






36. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






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






39. Receive incoming sensory information or send out motor impulse commands






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






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






42. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






43. Norepinephrine and serotonin






44. Adenine - Guanine - Thymine - Cytosine






45. The maintenance of water balance in the body






46. Symptom of narcolepsy - irresistible urge to






47. Accessory Nerve - moves the head






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






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






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