The most common form of spinal muscular atrophy is childhood proximal SMA.
Babies with spinal muscular atrophy type 1 typically have progressive muscle weakness and difficulty with movement. While treatments have improved outcomes, the condition usually affects physical growth and development. With early intervention and proper care, babies can achieve milestones and lead fulfilling lives, but they may not grow and develop in the same way as babies without the condition.
I have SMA type III (spinal muscular atrophy), a form of muscular dystrophy, and I have always seen and/or been treated by neurologists recommended by MDA. You can contact the national Muscular Dystrophy Association (MDA) either locally or online at http://www.mda.org for additional information or if you have questions you've been unable to find answers for. They are invaluable to families and individuals alike. Further personal research can be done using a search engine such as Google and entering the terms "neurology" and "muscular dystrophy."
Two conditionsa that affect the muscular system: Duchenne Muscle Dystrophy (DMD) and Myotonic Mucsle Dystrophy (MMD). DMD is the most common childhood form of muscular dystrophies while MMD is the most common adult form of muscular dystrophies.

Chordates are that group of animals having some form of a spinal column (which include the vertebrates).
Poliomyelitis can enter the central nervous system and destroy motor neurons that can cause paralysis and muscle weakness/atrophy. Spinal polio is the most common form. Poliomyelitis is caused by poliovirus and used to be a dreadful disease in the 20th century. Now with better vaccines, the number of polio incidents have gone down.
The adjective form of the noun muscle is "muscular" or "muscled" (or the rarer form muscly).
Myasthenia gravis: autoimmune to the ACh receptors at end plate (pathway >>> no muscle contraction) Muscular Dystrophy: genetic (X-linked) defect in dystrophin (pathway >>> myosin-actin crossbridge doesn't form > no muscle contraction)
The spinal nerves that originate from the thoracic portion of the spinal cord don't form plexuses. The word thoracic pertains to the thorax.
