Review the anatomy of the brain. (pg. 451)
Which portion is responsible for keeping you awake? (pg. 453) The epithalamus, pineal gland, functions much like the limbic system by influencing the secretion of melatonin associated with circadian rhythms.
Controlling thought? (pg. 452) They parietal lobe is involved in sensory association (storage, analysis, and interpretation of stimuli).
Emotions and behavior? (pg. 453) The hypothalamus is responsible for 2 major functions (1.) maintenance of a constant internal environment (2.) implementation of behavioral patterns. Integrative centers control ANS function, regulation of body temperature, endocrine function, and regulationof emotional expression.
Maintaining balance and posture? (pg. 455) The cerebellum is responsible for conscious and unconscious muscle synergy and for maintaining balance and posture. Where is the primary defect in Parkinsons disease and Huntingtons? (pg. 453) The basal ganglia system is believed to have a fine-tuning effect on motor movements. Parkinson's disease and Huntington's disease are associated with defects of the basal ganglia.
What is the function of the CSF? (pg 461) CSF is a clear, colorless fluid similar to blood plasma and interstitial fluid. The intracranial and spinal cord structures float in CSF and are thereby protected from jolts and blows. CSF also prevents the brain from tugging on meninges, nerve roots, and blood vessels. Where is CSF produced? (pg. 461) The choroid plexuses in the lateral, third, and fourth ventricles produce the major portion of CSF. Approximately 600cc of CSF is produced daily, and approximately 125-150cc is circulating in the ventricles and subarachnoid space at any given time.
Where is CSF absorbed? (pg. 461) CSF is reabsorbed into the venous circulation through the arachnoid villi, primarily located superior to the falx cerebri in the superior sagittal sinus. It
