One of the early symptoms of amyotrophic lateral sclerosis (ALS), often referred to as Lou Gehrig's disease, is skeletal muscle weakness. As the disease progresses, a patient with ALS loses voluntary movement. ALS is not a muscular disease; it is a degenerative neurological disorder in which motor neurons that cause skeletal muscles to contract are lost. Explain what is happening to a person with ALS who can still move his or her muscles but whose muscle contraction is weak.

Tara, a 16 -year-old girl, was rushed to the hospital after taking a bad spill off the parallel bars. After she had a complete neurological workup, her family was told that she would be permanently paralyzed from the waist down. During rehabilitation, her neurologist outlined for Tara and her parents the importance of preventing complications in such cases. Common complications include urinary infection, bed sores, and muscular spasms. Using your knowledge of neuroanatomy, explain the underlying reasons for these complications.
