| | Definition: | |
- A protruding mass of hardened plant tissue, often formed after an injury but sometimes a regular feature of the plant. Adj. callose.
- A small area of skin, usually on the foot, that has become thick and hard from rubbing or pressure. Calluses may lead to other problems such as serious infection. Shoes that fit well can keep calluses from forming.
- A callus of the skin is a marked piling up of surface keratin in the corneum (outermost layer) of the skin.
Callus formation at the ends of a fractured bone takes place within 10 days after the trauma and eventually it is replaced by new bone growth.
