Abstract

During a routine anatomical dissection we discovered an aberrant muscle slip associated with the pectoralis minor muscle that occurred bilaterally.  The muscle slips originated from ribs five or six and inserted into the tendon of the coracobrachialis in close proximity the coracoid process of the scapula.  Fibers of the muscle slip also blended with the pectoralis minor muscle on its lateral border.   The muscle slips were innervated by the medial pectoral nerve.  Reports and documentation of anatomical variants such as this provide an important resource for both researchers and clinicians. 
KEY WORDS: Pectoralis Minor, Variant, Axilla, Coracobrachialis.
