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. 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






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






3. 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






4. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






5. Made from within - natural






6. 'little brain'






7. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






8. Found in the ventricles and spinal canal






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






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






11. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






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

13. 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






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






15. Projects to ventral tegmental area






16. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






17. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






18. Consummatory stimulus






19. Sign






20. Cumulative effects of repeated stimulation from a presynaptic neuron






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






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






23. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






24. There are 12 add more






25. Hormones that reduce pain






26. Hypoglossal Nerve - moves the tongue






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






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






29. Includes the tectum and tegmentum






30. Optic Nerve - sight






31. Are found in the diencephalon






32. Trigerminal Nerve - face sensation






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






34. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






35. 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)






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






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






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






39. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






40. Caudate nucleus and putamen






41. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






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






43. An ovary or teste






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






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






46. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






48. 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






49. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






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