N: 1. muscle (n): late 14c., from Middle French muscle “muscle, sinew” (14c.) and directly from Latin musculus “a muscle,” literally “little mouse,” diminutive of mus “mouse”.
So called because the shape and movement of some muscles (notably biceps) were thought to resemble mice. The analogy was made in Greek, too, where mys is both “mouse” and “muscle,” and its comb. form gives the medical prefix myo-.
dysmorphia (adj): Late 19th century: from Greek dusmorphia ‘misshapenness, ugliness’, from dus- dys- + morphē ‘form’.

2. Muscle dysmorphia, which is also known as bigorexia, is an anxiety disorder which causes someone to see themselves as small, despite being big and muscular.

3. The condition can affect men and women, but one expert suggested many cases go unreported.

4. It is sometimes described as a kind of “reverse anorexia”.
