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. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






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






3. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






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






5. 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






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






7. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






8. Symptom of narcolepsy - irresistible urge to






9. Trigerminal Nerve - face sensation






10. Adenine - Guanine - Thymine - Cytosine






11. Abducens Nerve - moves eye






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






13. Is found between the dura mater and arachnoid mater meninges






14. 'little net'






15. Trochlear Nerve - moves eye






16. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






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






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






19. 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






20. Contains delta activity - stages III and IV






21. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






22. Facial Nerve - moves face and salivates






23. Hypothalamic-pituitary-adrenal axis -controls stress response






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

25. Hypoglossal Nerve - moves the tongue






26. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






27. All have similar molecular structure - so many 'dirty' medications






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






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






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






31. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






32. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






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






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






35. Is everything anterior to the central sulcus






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






37. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






38. Sleepwalking - sleep talking






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






40. Include tolerance (possible withdrawal) and sensitivity






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






42. Accessory Nerve - moves the head






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






44. The maintenance of water balance in the body






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






46. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






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






48. Most brain communications are with the opposite side of the body






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






50. Colored part of the eye
