Lunula, Explained
Quick definition
The pale crescent at the nail base — the visible part of the matrix where cells are born.
The lunula is front-line factory: matrix cells keratinize into the nail plate here. Damage it and the nail may grow ridged or temporarily misshapen.
Thumb lunulas are most visible; some people's are hidden entirely under the proximal fold — both normal.
