What's the difference between endogenous and extraneous?

Endogenous


Definition:

  • (a.) Increasing by internal growth and elongation at the summit, instead of externally, and having no distinction of pith, wood, and bark, as the rattan, the palm, the cornstalk.
  • (a.) Originating from within; increasing by internal growth.

Extraneous


Definition:

  • (a.) Not belonging to, or dependent upon, a thing; without or beyond a thing; not essential or intrinsic; foreign; as, to separate gold from extraneous matter.

Example Sentences:

  • (1) To evaluate threshold estimates under these conditions, computer simulations of experiments with small numbers of trials were performed by using psychometric functions based on a model of two types of noise: stimulus-related noise (affecting slope) and extraneous noise (affecting upper asymptote).
  • (2) Decisions concerning appropriate treatment are often made by patients, attorneys, the disability determination system, employers, and judges for extraneous reasons, which include financial gain or personal bias and often reflect lack of current information.
  • (3) In Experiment 1, subjects exposed to a sound representing their heartbeat made greater self-attributions for hypothetical outcomes than did subjects exposed to the same sound identified as an extraneous noise.
  • (4) A simple method of affinity purification, using antigen bound to nitrocellulose, is employed to remove the reactivity with these extraneous bands from immune sera.

  • (7) The chelating approach provides a powerful means for removing a single class of unwanted, random crosslinkages, i.e., those due to extraneous polyvalent metals such as lead, cadmium and aluminum.
  • (8) The results indicated that FF procedures are easily detected; therefore, difference found between the FF and CF groups may be influenced by extraneous variables.
  • (9) Phoneme identification responses collected in the same experiments, as well as informal observations about the quality of the restored phoneme, suggested that restoration of a fricative phone distinct from the extraneous noise did not occur; rather, the spectrum of the extraneous noise itself influenced phoneme identification.
