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






2. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






3. Sleepwalking - sleep talking






4. Trigerminal Nerve - face sensation






5. Symptom of narcolepsy - irresistible urge to






6. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






7. 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






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






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






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






11. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






12. Are found in the diencephalon






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






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






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






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






17. 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






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






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






20. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






21. Most pervasive excitatory neurotransmitter in the brain






22. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






23. An area that combines input from diverse brain regions






24. 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






25. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






26. 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






27. 'little brain'






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






29. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






30. Accessory Nerve - moves the head






31. Self-dissolving






32. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






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






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






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






36. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






37. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






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






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






40. There are 12 add more






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






42. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






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






44. Transparent substance between lens and retina






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






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






47. 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






48. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






49. 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
