callus

callus
Noun
pl: calluses

This term describes a protective biological response to stress, whether on the skin's surface or within the skeletal system. In a dermatological sense, it carries a connotation of toughness and endurance, often associated with manual labor or athletic training. It is distinct from a blister, which is a fluid-filled pocket, as a callus is a dense, dry accumulation of keratin.

In medical orthopedics, the term refers to the bridge of new bone that stabilizes a fracture. This usage is highly technical and describes a regenerative process rather than a response to external friction. While the skin-based meaning is common in everyday conversation, the bony meaning is restricted to clinical contexts.
