What best defines Amyotrophic Lateral Sclerosis ALS "Lou Gehrig Disease?"
Loss of motor neurons in the brain
Loss of sensory neurons in the anterior horn of the spinal cord
Loss of motor neurons in the anterior horn of the spinal cord and loss of motor nuclei of the lower brainstem
All of the above
The Correct Answer is C
Choice A: Loss of motor neurons in the brain is not a complete definition of ALS, as it does not include the loss of motor neurons in the spinal cord and brainstem.
Choice B: Loss of sensory neurons in the anterior horn of the spinal cord is not a correct definition of ALS, as it involves sensory neurons, not motor neurons.
Choice C: Loss of motor neurons in the anterior horn of the spinal cord and loss of motor nuclei of the lower brainstem is a correct definition of ALS, as it describes the progressive degeneration and death of both upper and lower motor neurons that control voluntary muscle movements²⁴.
