  17. Middle layer of the meninges. Soft, spongy, web-like layer.
    Arachnoid membrane
  18. Filled with cerebrospinal fluid that is produced by the choroid plexus.
    Subarachnoid space
  19. Inner layer of the meninges. Close to the brain and the spinal cord.
    Pia mater
  20. The PNS has what kind of meninges?
    Dura mater and pia mater. 
  21. Brain contains hollow, connected chambers that are filled with cerebrospinal fluid. What are they called?
  22. The largest ventricles, also called the 1st and 2nd ventricles.
    Lateral ventricles
  23. The ventricle that is the midline of the brain. It is rich in choroid plexus. Becomes a landmark for finding the thalmus. Also a major producer of cerebrospinal fluid.
    3rd ventricle
  24. This connects the 3rd and 4th ventricle
    Cerebral aqueduct
  25. Receives visual information, calcarine fissure.
    Primary visual cortex
  26. Receives auditory information, a lateral fissure.
    Primary auditory cortex
  27. Receives body senses, central sulcus.
    Primary somatosensory cortex
  28. Information processor for primary sensory cortex, perception, memory.
    Sensory association cortex
  29. Processes movements
    Motor association cortex
  30. Involved in formulating plans and strategies
    Prefrontal cortex
  31. Deep grooves found on the surface of the brain. The deepest grooves
  32. Shallower grooves on the brain.
  33. This groove divides the somatosensory cortex from the motor cortex.
    Central sulcus
  34. Bumps on the brain
  35. Lobe in front of the central sulcus. Cognition and memory. 
    Frontal lobe
  36. Area in the brain the has the ability to concentrate and attend, elaboration of thought. Judgment, inhibition. Personality and emotional traits.
    Prefrontal area
  37. Lobe posterior to the central sulcus. Processing of sensory input, sensory discrimination, body orientation, and primary secondary somatic area.
  38. Lobe ventral to lateral fissure. Auditory receptive area and association areas, expressed behaviors, language and memory.
  39. Lobe at the back of the brain. Used for vision.
  40. Includes the cingulate gyrus and corpus collosum.
    Limbic cortex
  41. Part of the limbic system involved with learning and memory
  42. Part of the limbic system specific to emotion and memory
  43. Part of the limbic system that connects axons from the hippocampus to other regions of the brain.
  44. Part of the limbix system that contains parts of the hypothalmus
    Mammilary bodies
  45. Nuclei, deep in the brain, beneath the lateral ventricles. Comprised of the caudate nucleus, putamen, and the global pallidus.
    Basal ganglia
  46. This is involved in smoothing out movement via input from the primary and secondary motor cortex of the somatosensory cortex.
    Basal ganglia
  47. Part of the diencephalon that has 2 lobes connected through the 3rd ventricle via massa intermedic. It is divided into several (nodes?) interonnectin different regions of the brain.
  48. Areas where we find the dense body of somas interconnecting with dendrites and axons synapsing onto these.
  49. Part of the thalmus, used for vision.
