Is muscle atrophy typically observed as a symptom of lower or upper motor neuron lesions?

Correct answer is A) Muscle atrophy is typically observed as a symptom of lower motor neuron lesions, which include conditions like amyotrophic lateral sclerosis (ALS) and spinal muscular atrophy. B) Incorrect. Muscle atrophy is not primarily associated with upper motor neuron lesions; upper motor neuron lesions tend to cause muscle weakness and spasticity. C) Incorrect. While muscle atrophy can occur in both lower and upper motor neuron lesions, it is more commonly associated with lower motor neuron lesions. D) Incorrect. Muscle atrophy is observed in certain neurological conditions and is particularly common in lower motor neuron lesions, making this statement inaccurate.
