Although anatomical variations in the upper limb are frequent, coexistence of multiple combined variations is rare. During a routine educational dissection at Jeju National University Medical School, three muscular variations were found in a 75-year-old Korean male cadaver, in which a supraclavicular cephalic vein was also found in ipsilateral upper extremity during skinning. Here we describe characteristics of the pectoralis quartus muscle, the supernumerary head of biceps brachii muscle and an accessory head of flexor digitorum profundus muscle, and discuss their coexistence from morphological and embryological points of view.

The jugulocephalic anastomosis is a rare anatomical variant which normally undergoes atrophy during embryonic development. We found 2 cases of the jugulocephalic vein variant with supraclavicular course in Korean male cadavers. In a 50-year-old cadaver, the right cephalic vein ascended anterior to the clavicle, and terminated into the external jugular vein as well as to the axillary vein through a classic branch. In a 76-year-old cadaver, the left cephalic vein ascended supraclavicular course without any branch to the axillary vein, and terminated to the external jugular vein. We discussed the embryological explanation as well as its frequency since this jugulocephalic vein variant could cause unpredicted danger during clinical procedures.
