ABSTRACT
During routine dissection practice a supernumerary muscle was found on the right side infraclavicular region of a male cadaver. This muscle was arising from the superior surface of the first rib and its coastal cartilage and inserted to a thick ligament that extended from the medial end of the suprascapular notch to the capsule of the acromioclavicular joint. This accessory muscle slip was innervated by a branch from the nerve to subclavius. According to its location and innervation the aberrant muscle was considered to be the subclavius posticus. The anatomic relationships of the muscle make it clinically significant.
RESUMEN
Durante una disección de rutina, un músculo supernumerario fue encontrado en el lado derecho de la región infraclavicular de una cadáver de sexo masculino. Este músculo se originaba de la superficie superior de la primera costilla y cartílago costal y se insertaba en un grueso ligamento que se extendía desde la parte medial de la incisura supraescapular a la cápsula de la articulación acromioclavicular. Este músculo estaba inervado por un ramo del nervio subclavio. De acuerdo a su localización e inervación el músculo aberrante fue considerado como el músculo subclavio posticus. Las relaciones anatómicas del músculo tienen significancia clínica.
