  1. 1. The Brain Presentation 2 Cynthia GalvezJune 2012 Biology 120: Medical Terminology 1
  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  Frontal Lobe: controls motor function, personality, speech  Parietal Lobe: explains language, analyzes nerve impulses  Occipital Lobe: Vision  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  Malignant Tumor  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
