Intrinsic
Definition:
(a.) Inward; internal; hence, true; genuine; real; essential; inherent; not merely apparent or accidental; -- opposed to extrinsic; as, the intrinsic value of gold or silver; the intrinsic merit of an action; the intrinsic worth or goodness of a person.
(a.) Included wholly within an organ or limb, as certain groups of muscles; -- opposed to extrinsic.
