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. 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






2. Are found in the diencephalon






3. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

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






5. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






6. 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






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






8. The maintenance of water balance in the body






9. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






10. Is used as an anaesthetic for children and animals but causes psychosis in adults






11. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

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






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






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






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






16. Cumulative effects of repeated stimulation from a presynaptic neuron






17. Most pervasive excitatory neurotransmitter in the brain






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






19. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






20. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






21. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






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






23. Colored part of the eye






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






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






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






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






28. Two different presynaptic neurons/inputs to a post-synaptic cell






29. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






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






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






32. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






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






34. 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)






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






36. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






37. Caudate nucleus and putamen






38. Found in the ventricles and spinal canal






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






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






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






42. 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






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






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






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






46. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






47. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

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






49. Produce drowsiness and sleepiness






50. Glossopharyngeal Nerve - taste swallow
