52 year old woman has ALS, after not being able to stand for long (parts…

- - - - contains interneurons
    - - contains motor neurons
    - - contains autonomic motor neurons
  - - - leaves anterior side of spinal cord carrying motor neurons
    - - enters posterior side of spinal cord, carrying sensory neurons
- - - - 1st order: has receptors & brings info to spinal cord
      - 2nd order: interneurons in dorsal horn of spinal cord
      - 3rd order: neurons in thalamus that connects w/ cerebral cortex
  - - - contains motor neurons
        
        upper motor neurons
        
        in brain or brainstem
        
        lower motor neurons
        
        neuron that synapses w/ muscle
- - - - if this happens, you will need to wear a device to help you breath, such as continuous positive airway pressure (CPAP)
  - - - patients will often have to rely on comm. tech. to coomunicate
  - - - treatments include medication, changing whole foods to liquid
  - - - treatments include various medications such as cholinesterate inhibitors to boost chemical messengers involved w/ memory & judgement
- - - - 5-10% of people w/ ALS inherit it
    - - as you increase in age, risk for developing ALS increases
    - - before age of 65, men develop ALS a little more
    - - smoking can increase chance of developing ALS, especially for women after menopause
      - toxin exposure
        
        some studies show that exposure to certain toxins may increase likelihood of ALS
      - military service
        
        studies show that those who have served are at a greater chance of developing ALS
        
        this may happen due to certain metals, chemicals, injuries, infections, & exertion of muscles
  - - - causes motor neurons to gradually deteriorate, resulting in no messages being sent to muscles
