  1. 1. Presentation: Chapter 12 Phil Traini
  2. 2. Medical terminology • Medical terminology is a language of its own. This language helps professionals accurately describe the human body along with any conditions associated with it in a scientific manner. • There are 3 parts when considering the systematic approach of creating a word: prefixes, word roots, and suffixes. • So these parts of words help
  3. 3. Suffix Defined • What is a suffix? • A suffix is placed at the end of the root word in order to add meaning in terms of condition, disease, and/or procedure. • Examples: • One suffix example is -plegia. -Plegia means paralysis and can help identify the condition and individual is suffering from after properly identifying the root word. • A second example is -phasia. -Phasia means speech. •
  4. 4. Suffix -Plegia relating to nervous system • In the nervous system chapter of our textbook there are two disorders referring to -plegia: quadriplegia and paraplegia. Both of these disorders relate to paralysis within the human body.
  5. 5. Quadriplegia • Quadriplegia occurs when paralysis takes place in all four limbs. • This can be caused by spinal trauma affecting the cervical part of the spine C1-C7 and also inflammation or tumor growth in this location. • Diseases that can cause quadriplegia such as multiple sclerosis, transverse myelitis, and polio. • Disorders such as muscular dystrophy and spastic cerebral palsy can also cause quadriplegia.
  6. 6. Paraplegia • Paraplegia is defined as paralysis of the legs and lower body, typically caused by spinal injury or disease. • It usually occurs form trauma, inflammation(through infection or trauma), or tumor growth on the lumbar region of the spine L1-L5. • Autoimmune disorders, hereditary spastic paraplegia, syrinx, multiple sclerosis, spina bifida, and other disorders.
  7. 7. Suffix -phasia relating to nervous system • In the nervous system chapter of our textbook two disorders a mentions that have the suffix -phasia. They are aphasia and dysphasia. Both of these disorders affect speech. • Both of these disorders are related to issue with the Broca and Wernicke areas of the brain.
  8. 8. Aphasia • This disorder refers to the complete inability to communicate verbally or in writing. • A breakdown of this work (a- without, phasia-speech) • Causes of this disorder can result from traumatic damage to the Broca's and Wernicke's regions of the brain or the neural pathways between them. • Brain tumors and disorders such a Alzheimer’s and Parkinson’s disease can also cause aphasia. • Herpesviral encephalitis can cause aphasia. • Epilepsy and severe migraines can sometimes cause episodic aphasia.
  9. 9. Dysphasia • When broken down (dys- means abnormal, difficult -phasia speech). • Dysphasia is difficulty verbally communicating and also writing. • Although it is different than aphasia sometimes the two are used interchangeably. • The most common cause of dysphasia is a stroke. • It can also be caused by trauma, infection, and tumor growth in the Broca’s and Wernicke’s areas of the brain.
