Amyotrophic Lateral Sclerosis (ALS): Nerve and Muscle Degeneration Explained #3658630 (License: Personal Use)

The image contrasts a functional motor neuron synapsing with muscle tissue-enabling contraction-with a deteriorating neuron in ALS, where axonal degeneration disrupts signal transmission. In the diseased state, the nerve terminal retracts and loses connection, resulting in flaccid paralysis. This illustrates the hallmark pathophysiology of ALS: progressive loss of upper and lower motor neurons.

Used in medical education, patient information pages, or neurology resource sites to explain ALS mechanisms; targets users seeking to understand disease progression, symptoms, or neuropathology at a visual level.
