What's the difference between callus and wear?

Callus


Definition:

  • (n.) Same as Callosity
  • (n.) The material of repair in fractures of bone; a substance exuded at the site of fracture, which is at first soft or cartilaginous in consistence, but is ultimately converted into true bone and unites the fragments into a single piece.
  • (n.) The new formation over the end of a cutting, before it puts out rootlets.

  • (19) Bone union can be achieved under external fixation through different pathways, ranging from callus-free gap healing under a rigid neutralization configuration to direct-contact healing with periosteal new bone formation under axially dynamized stable fixation.
  • (20) We compare the gene activity in heterozygotes versus homozygotes, and show variation in activity between plants regenerated independently from the same transformed callus.

Wear


Definition:
