This Concept Map, created with IHMC CmapTools, has information related to: cns-other, CNS-other protected by meninges, arachnoid mater- separated from dura by subdural space; contains subarachnoid space for CSF then pia mater- connective tissue that clings tightly to brain, reticular formation function Has Reticular activating system (RAS), which maintains consciousness & filters out stimulus; has some role in motor activity esp visceral motor activity, CSF circu choroid plexus in epithalamus cleanse csf by removing wastes, meninges function cover & protect; blood vessels; house CSF; forms partitions in skull, meninges composed of dura mater (outside layer) hard layer, CNS-other protected by bones, CSF function cushions & protects; sterile fluid; carries some nourishment, CNS-other functional brain system reticular formation, dura mater (outside layer) hard layer then arachnoid mater- separated from dura by subdural space; contains subarachnoid space for CSF, limbic system function plays huge role in emotion; puts emotional assoc w/odors; interacts w/prefrontal lobes, allowing us to be conscious of emotions; contains hippocampal regions which convert short term memory to long term memory., CNS-other protected by CSF, CNS-other brain waves alpha-idling brain beta-alert theta-common in children, abnormal in adults delta-deep sleep, CNS-other protected by blood brain barrier, CNS-other functional brain system limbic system
