Termination

  • the muscle finishes on the angle apico-médial (or supéro-medial) of the scapula.

Action

  • If this muscle is lifting scapula, it is also, with the Muscle rhomboïde, rapprochor of the member on the thorax by rotation médiale or spinale (in the direction of the needles of a watch) which it involves.
