What term describes a group of inherited muscular disorders leading to muscle weakness?

The term that describes a group of inherited muscular disorders leading to muscle weakness is Muscular Dystrophy. This condition is characterized by progressive degeneration and weakness of the muscles that control movement. The term itself signifies that these disorders are primarily related to muscle (muscular) dysfunction (dystrophy), often due to genetic mutations that affect the proteins necessary for muscle health.

In contrast, Marfan Syndrome is a genetic disorder that affects connective tissue, leading to features like tall stature and cardiovascular complications, but it is not primarily a muscular disorder. Connective Tissue refers to various types of tissues that support, bind together, and protect organs, rather than specifically addressing muscle weakness. Epithelial Tissue, meanwhile, consists of sheets of cells that cover body surfaces and line cavities, which does not pertain to inherited muscular disorders at all.

Understanding these distinctions helps to clarify why Muscular Dystrophy is the correct term for a group of conditions that primarily impact muscular strength and integrity.
