Is the progressive weakness and size reduction of muscle tissue

atrophy

Explanation:

Atrophy is a term that describes a progressive weakness that results in decreased cell tissue. On a larger scale, atrophy may be a reduction in size and function of a muscle or limb. This process can often be gradual and chronic and even permanent. However, atrophy is not exclusively a pathological state. Atrophy is actually a part of our natural homeostatic development. The wrinkles that appear on our faces as we get older are stunted, as are our thinning hair and tooth loss.

There are many reasons why a tissue may atrophy. It can be caused by age or genetics, such as inheriting a faulty set of genes that signal cell lysis or inhibit the assembly of a crucial protein in muscle cell formation. The inevitable consequence of cellular atrophy is that it impairs the impacted limb's ability to perform its functions. However, the actual degree of damage depends on its partial or complete effect and the type of atrophy.
