What's the difference between mucin and mucus?

Mucin


Definition:

  • (n.) See Mucedin.
  • (n.) An albuminoid substance which is contained in mucus, and gives to the latter secretion its peculiar ropy character. It is found in all the secretions from mucous glands, and also between the fibers of connective tissue, as in tendons. See Illust. of Demilune.

Mucus


Definition:

  • (n.) A viscid fluid secreted by mucous membranes, which it serves to moisten and protect. It covers the lining membranes of all the cavities which open externally, such as those of the mouth, nose, lungs, intestinal canal, urinary passages, etc.
  • (n.) Any other animal fluid of a viscid quality, as the synovial fluid, which lubricates the cavities of the joints; -- improperly so used.
