Regulative patterns: 6 points
(1) nervous regulation [2`];  (2) humoral regulation [2`];  (3) autoregulation; [2`].
Each characteristic: 9 points
(1) nervous regulation is rapid, temporal, accurate, sensitive, dominant and most important pattern, and it always depends on reflex activities to display function [4`].
(2) humoral regulation is slow, persistent, extensive, torpent, subordinate and secondary important pattern, and it always counts on biological active material, e.g., hormone or enzyme release to show effect [3`].
(3) autoregulation is independent of nervous and humoral factors, and its impact is small, local and limited but useful. [2`].
