Adductor \Ad*duc"tor\, n. [L., fr. adducere.] (Anat.)
   A muscle which draws a limb or part of the body toward the
   middle line of the body, or closes extended parts of the
   body; -- opposed to {abductor}; as, the adductor of the eye,
   which turns the eye toward the nose.

         In the bivalve shells, the muscles which close the
         values of the shell are called adductor muscles.
                                                  --Verrill.
