Wound tissue, parenchyma tissue formed on or below a wounded surface.
A mass of blood and granulation tissue, containing bone-forming cells, that forms around the bone ends following a fracture.

Thickening of the skin caused by continued, repeated pressure on any part of the skin, specially the hands and feet.
The parenchymal tissue that originates from cambium and forms due to injury, infection caused by microorganisms, and other related factors.
Thickened skin, a result of persistent friction or irritation over an extended period, manifests as a consequence.
The fresh bone formed at a fracture location, connecting the separated portions of a fractured bone.
