What's the difference between appendage and appendix?

Appendage


Definition:

  • (n.) Something appended to, or accompanying, a principal or greater thing, though not necessary to it, as a portico to a house.
  • (n.) A subordinate or subsidiary part or organ; an external organ or limb, esp. of the articulates.

Appendix


Definition:

  • (n.) Something appended or added; an appendage, adjunct, or concomitant.
  • (n.) Any literary matter added to a book, but not necessarily essential to its completeness, and thus distinguished from supplement, which is intended to supply deficiencies and correct inaccuracies.

Example Sentences:

  • (1) Life events were collected (using the Bedford College method) in 78 women patients aged 15-40 yr, of whom 39 were admitted for the removal of an appendix which proved to be normal at operation and in whom no organic cause for their pain was found, and a matched group of 39 parasuicide patients.
  • (2) The age distribution for Caulobacter cells in an exponential population has been calculated (Appendix by Robert Tax) and used to analyze some of the results.
  • (3) As the differential diagnosis between Crohn's disease and appendicitis is difficult and the surgical approach to the appendix in the presence of Crohn's disease is controversial, we illuminate some practical points in the preoperative evaluation of these patients and deal with the question of whether appendectomy should be performed in these patients.
  • (4) Pathologic examination revealed no endometriosis, but examination of the distal appendix showed structural disorganization of its entire wall, with lack of proper differentiation of its normal coats and irregular overgrowth of fibroadipose, fibromuscular, and neural elements.
