What's the difference between apophysis and protuberance?

Apophysis


Definition:

  • (n.) A marked prominence or process on any part of a bone.
  • (n.) An enlargement at the top of a pedicel or stem, as seen in certain mosses.

Protuberance


Definition:

  • (n.) That which is protuberant swelled or pushed beyond the surrounding or adjacent surface; a swelling or tumor on the body; a prominence; a bunch or knob; an elevation.
