The superficial marking of Moderator band on the sternocostal surface of the right ventricle is marked. Materials   and   Methods:   50   Formalin   soaked   cadaveric   Hearts   were   taken   from   the   department   of   Anatomy   of   KSHEMA.   36   Males   and   14   Female   Hearts were   tagged   according   to   ascending   order   of   the   age.   Moderator   band,surface   marking   on   sterocostal   surface   ,   the   angle   with   the   anterior   papillary   Muscle ect are Noted. Result: The morphological variations are noted. The results are compared with gender, with the previous results . Conclusion:   There   is   a   difference   in   the   course   of   moderator   band.   In   60%the   moderator   band   runs   downwards   and   to   the   right,   in   30%   it   is   found   to   be horizontal   and   in   10%   runs   upwards   and   to   the   right.   The   difference   is   found         in   males   and   females.as   well.   The   surface   marking   of   moderator   band   on sternocostal   surface   of   the   heart   measures   more   due   to   the   convexity   of   the   right   ventricular   surface.   This   knowledge   will   help   in   accurate   detection   of   the moderator band by echocardiography and in surgeries.
