"An instinct is a propensity prior to experience, and independent of instructions." (Paley) "An instinct is a blind tendency to some mode of action, independent of any consideration, on the part of the agent, of the end to which the action leads." (Whately) "An instinct is an agent which performs blindly and ignorantly a work of intelligence and knowledge." (Sir W. Hamilton) "By a divine instinct, men's minds mistrust Ensuing dangers." (Shak) 2. <zoology> Specif, the natural, unreasoning, impulse by which an animal is guided to the performance of any action, without of improvement in the method. "The resemblance between what originally was a habit, and an instinct becomes so close as not to be distinguished." (Darwin) 3. A natural aptitude or knack; a predilection; as, an instinct for order; to be modest by instinct. Origin: L. Instinctus instigation, impulse, fr. Instinguere to instigate: cf. F. Instinct.

| amyloid p component | Amyloid p component is a small, non-fibrillar glycoprotein found in normal serum and in all amyloid deposits. It has a pentagonal (pentaxin) structure. It acts as an acute phase protein in the mouse, modulates immunologic responses in man, inhibits elastase, and has been suggested as an indicator of liver disease. (12 Dec 1998) |
| anterior component of force | A force operating to move teeth anteriorly. (05 Mar 2000) |
| blood component removal | Any procedure in which blood is withdrawn from a donor, a portion is separated and retained and the remainder is returned to the donor. (12 Dec 1998) |
| blood component transfusion | The transfer of blood components such as erythrocytes, leukocytes, platelets, and plasma from a donor to a recipient or back to the donor. This process differs from the procedures undertaken in plasmapheresis and types of cytapheresis (plateletpheresis and leukapheresis) where, following the removal of plasma or the specific cell components, the remainder is transfused back to the donor.
