Variations in the arterial pattern of the upper limb are frequently encountered during dissection of the human body. However, multiple variations in one limb are infrequently encountered. Dissection of the left amputated upper limb, 15 cm above the intercondyler line, of a female cadaver revealed the following variations. 1. The superficial brachial artery descends behind the bicepital apneurosis and continues as the radial artery. 2. The deep (definitive) brachial artery continues in the forearm as the ulnar artery under the superficial flexor muscles of the forearm. 3. The median artery arises from the ulnar artery 5 cm below the intercondyler line and continues deep to the flexor retinaculum. 4. The median artery terminates in the hand as princeps pollicis and radials indicis arteries. 5. The median nerve forms a loop surrounding the median artery 4 cm below the intercondyler line and bifurcates 2 cm above the flexor retinaculum.

UI	MeSH Term	Description	Entries
D008475	Median Nerve	A major nerve of the upper extremity. In humans, the fibers of the median nerve originate in the lower cervical and upper thoracic spinal cord (usually C6 to T1), travel via the brachial plexus, and supply sensory and motor innervation to parts of the forearm and hand.	Median Nerves,Nerve, Median,Nerves, Median
D001916	Brachial Artery	The continuation of the axillary artery; it branches into the radial and ulnar arteries.	Arteries, Brachial,Artery, Brachial,Brachial Arteries
D002102	Cadaver	A dead body, usually a human body.	Corpse,Cadavers,Corpses
D004210	Dissection	The separation and isolation of tissues for surgical purposes, or for the analysis or study of their structures.	Dissections
D005260	Female		Females
D006225	Hand	The distal part of the arm beyond the wrist in humans and primates, that includes the palm, fingers, and thumb.	Hands
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D001132	Arm	The superior part of the upper extremity between the SHOULDER and the ELBOW.	Brachium,Upper Arm,Arm, Upper,Arms,Arms, Upper,Brachiums,Upper Arms
D017534	Radial Artery	The direct continuation of the brachial trunk, originating at the bifurcation of the brachial artery opposite the neck of the radius. Its branches may be divided into three groups corresponding to the three regions in which the vessel is situated, the forearm, wrist, and hand.	Arteries, Radial,Artery, Radial,Radial Arteries
D017535	Ulnar Artery	The larger of the two terminal branches of the brachial artery, beginning about one centimeter distal to the bend of the elbow. Like the RADIAL ARTERY, its branches may be divided into three groups corresponding to their locations in the forearm, wrist, and hand.	Arteries, Ulnar,Artery, Ulnar,Ulnar Arteries
