THORACIC OUTLET SYNDROME SERIES - PART 4 - PECTORALIS MINOR SYNDROME The pec minor originates on the coracoid process on the front of the scapula and splits into three sections that travel diagonally downward and medial to attach to the 3rd to 5th ribs. Contraction of the pec muscle pulls the shoulder blade downward (depression) and forward (protraction) on the ribcage. Conversely, if the shoulder is held in place by the levator scapula and trapezius muscles, contraction of the pectoralis minor
