Nervous System (Multiple sclerosis (MS) (TX (no cure, symptoms treated by…

- - - - symptomatic flare-ups, patient has times with no symptoms (remission)
    - - no remission period, patient becomes more disabled
- - - - initial onset of disease; patient steadily worsens
    - - patient recovers functions
    - - days to weeks; patient condition is stable
- - - - cell metabolism
    - - receives info from the enviroment
    - - generates and sends signals to other cells
    - - where signal leaves cells
    - - axon terminal and receiving cell combine
  - - - 1 axon and 1 dendrite
    - - 1 axon and many dendrites/branches
    - - 1 process that splits into central peripheral projections
- - - - respiratory treatment
      - BP adnormalities
      - pneumonia
      - blood clots
      - organ dysfunction
      - pressure ulcers
      - pain
      - bladder and bowel movement
- - - - keyboard, mouse, microphone
    - - hard drive, random access memeory
    - - central processing units
    - - cables to printers, displays, speakers
- - - - astrocytes
        
        metabolic/structural support, hold neurons/blood vessels close together
      - microglia
        
        remove debris and microbes
      - ependymal
        
        cover/line cavities of NS
      - oligodendrocytes
        
        hold nerve fibers together and make lipid insulation
- - - - either cell has 1 or not
    - - always finish and will be same size; local potentials add together to form action potential
- - - - parasympathetic nervous system
        
        deals with normal body functioning and maintain homeostasis
      - sympathetic nervous system
        
        controls "fight or flight" response system
