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. 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)


2. Trochlear Nerve - moves eye






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






4. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






5. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






6. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






7. Is found in the interior rostral temporal lobe - part of limbic system






8. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






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






10. Facial Nerve - moves face and salivates






11. 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






12. Vagus Nerve - heart rate and digestion






13. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






14. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






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






16. Absolute; relative






17. Made from within - natural






18. Sleepwalking - sleep talking






19. Adenine - Guanine - Thymine - Cytosine






20. Transparent substance between lens and retina






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






22. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






23. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






24. 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






25. Accessory Nerve - moves the head






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






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






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






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






30. 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






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






32. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






33. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






34. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






35. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






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






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






38. Maintains balance/posture and coordinates body movements






39. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






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






41. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






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






43. Projects to ventral tegmental area






44. ...






45. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






46. Skin senses that register the sensations of pressure - warmth and cold






47. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






48. The maintenance of water balance in the body






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






50. Olfactory Nerve - smell
