1 belonging to a thing by its very nature; "form was treated as something intrinsic, as the very essence of the thing"- John Dewey [syn: intrinsical] [ant: extrinsic]
2 situated within or belonging solely to the organ or body part on which it acts; "intrinsic muscles"
Intrinsic describes a characteristic or property of some thing or action which is essential and specific to that thing or action, and which is wholly independent of any other object, action or consequence. A characteristic which is not essential or inherent is extrinsic.
For example in biology, intrinsic effects originate from "inside" an organism or cell, such as an autoimmune disease or intrinsic immunity.
