Answer:
The lungs have no skeletal muscles of their own. ... The diaphragm, a dome-shaped sheet of muscle that separates the chest cavity from the abdomen, is the most important muscle used for breathing in (called inhalation or inspiration).
Brain-lung-thyroid syndrome is a group of conditions that affect the brain, lungs, and thyroid gland (a butterfly-shaped gland in the lower neck). Brain-lung-thyroid syndrome historically included problems with all three organs, although the designation now encompasses a combination of brain, lung, and thyroid problems. About 50 percent of affected individuals have problems with all three organs, about 30 percent have brain and thyroid problems, and about 10 percent have brain and lung problems. The brain alone is affected in 10 to 20 percent of people with the condition. Such cases are sometimes called isolated benign hereditary chorea.
