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. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

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






3. Self-dissolving






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






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






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






7. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






8. Glossopharyngeal Nerve - taste swallow






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






10. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






11. 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






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






13. Is characteristic of indirect antagonists






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






15. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






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






17. Accessory Nerve - moves the head






18. Precursor to the catecholamine neurotransmitters (DA + NE)






19. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






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






21. Trochlear Nerve - moves eye






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






23. 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)






24. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






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






26. Regulates body temperature






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






28. Audition: protrusions on top of midbrain; part of auditory system






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






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






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






32. 'little net'






33. Trigerminal Nerve - face sensation






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






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






36. Hormones that reduce pain






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






38. Is an oversensitivity to dopamine (D2)






39. Is characteristic of indirect antagonist drugs






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






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






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






43. Olfactory Nerve - smell






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






45. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






46. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






47. Expression of traits






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






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






50. 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)
