  2. 2. The BrainJune 2012 Biology 120: Medical Terminology 2
  3. 3. What is a brain?   Part of the Nervous System   Coordinates most of the bodies activities   One of the largest organs in the body   Center of all though, memory, judgment, emotions   Each part of the brain is responsible for controlling different body functionsJune 2012 Biology 120: Medical Terminology 3
  4. 4. Four Main Sections of the Brain   Cerebrum   Cerebellum   Diencephalon   Brain StemJune 2012 Biology 120: Medical Terminology 4
  5. 5. Cerebrum   Largest section of the brain   Located in upper section   Processes thoughts   Judgments   Memory   Divided into left and right halves   Cerebral hemisphere   4 lobes in each hemisphere 1.  Frontal Lobe: controls motor function, personality, speech 2.  Parietal Lobe: explains language, analyzes nerve impulses 3.  Occipital Lobe: Vision 4.  Temporal Lobe: Hearing, smellJune 2012 Biology 120: Medical Terminology 5
  6. 6. Cerebellum   2nd largest section of the brain   Coordinates body movement   Maintains equilibrium   Maintains BalanceJune 2012 Biology 120: Medical Terminology 6
  7. 7. Diencephalon   Located bellow the cerebrum   Thalamus   Composed of gray matter   Center for transmitting impulses from eyes, ears and skin to cerebrum   Controls pain   Hypothalamus   Controls systems   Autonomic nervous system   Cardiovascular system   Digestive system   Release hormones from pituitary glandJune 2012 Biology 120: Medical Terminology 7
  8. 8. Brain Stem   3 components   Midbrain   Connects brain impulses and spinal cord   Pons   Connects cerebellum and brain   Medulla oblongata   Connects brain to spinal cord   Controls respiration, heart rate, temperature and blood pressureJune 2012 Biology 120: Medical Terminology 8
  9. 9. Brain Cavities   Four cavities known as ventricles   Ventricles contains Cerebrospinal fluid   A protection fluid that prevents shock or movement to brain and spinal cord   Locations   Right hemisphere   Left hemisphere   Thalamus   Front CerebellumJune 2012 Biology 120: Medical Terminology 9
  10. 10. Brain Tumor   What is a Brain Tumor?   An intracranial mass,   Either benign or malignant   Benign Tumor   Can be fatal; causes pressure on normal brain tissue   MalignantTumor   Cancerous   Generally progressive and recurringJune 2012 Biology 120: Medical Terminology 10
  11. 11. Dementia   Progressive loss of cognitive ability   Impairment on performing daily activities   Common in the elderly   Symptoms present for over 6 monthsJune 2012 Biology 120: Medical Terminology 11
  12. 12. Alzheimer Disease   Form of dementia   No cure   Chronic mental disorder   Loss of memory, disorientation   Symptoms get worse with time   Occurs in people age 40-65   Earlier than age 40, early-onset Alzheimer DiseaseJune 2012 Biology 120: Medical Terminology 12
  13. 13. Medical Terminology   Neur/o – pertaining to nervous system   Neurology-study of nervous system   Neurologist- someone who studies nervous system   Neuroma- swelling of brain, cancerous tumor in brainJune 2012 Biology 120: Medical Terminology 13
