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






2. Oculomotor Nerve - moves eye pupil






3. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






4. Affect multiple receptors; highly preferential to which type of receptor they affect






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






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






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






8. Self-dissolving






9. Important to motor system






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






11. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






12. Optic Nerve - sight






13. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






14. An ovary or teste






15. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






16. Olfactory Nerve - smell






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






18. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






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






20. Most pervasive excitatory neurotransmitter in the brain






21. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






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






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. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






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






26. Maintains balance/posture and coordinates body movements






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






28. Accessory Nerve - moves the head






29. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






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






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






32. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






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






35. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






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






37. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






38. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






39. Is characteristic of indirect antagonists






40. If head is rotated - eye movements occur in the same direction






41. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






42. Found in the hypothalamus - function to maintain the water balance in the body






43. Moving forward






44. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






45. Damage to this are causes clumsiness and loss of balance






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






47. Transparent substance between lens and retina






48. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






49. 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






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