(From cubitus, elbow). See Cervicales. Cheselden describes the cubical nerves as being two in each arm: the upper passing over the upper exuberance of the os humeri, runs on to the thumb and the three next fingers by its branches, which spread when it approaches the thumb; the inferior, which passes under the inner exuberance of the os humeri, and runs on to the ring and little fingers. For this reason we find these fingers often affected, while the others remain free from disease.

Cubitalis, vel ulnaris arteria. The cubital or ulnar artery, parting from the radical about a finger's breadth below the bend of the arm, sinks in between the ulna and the upper parts of the pronator teres, perforates the palmaris longus, and radiaeus inter-nus: near the carpus it lies just under the integuments, is continued on the inside of the os pisiforme, runs before the annular ligaments across the palm, and forms an arch which anastomoses with that of the radial; whence these arteries go to the finger and thumb, one running on each of the fingers. In its course it sends off various branches.
