How many bones are conterminous to the first wrist bone

The first bone [os scaphoideum], besides being articulated to the radius, is also articulated to the second carpal bone [os lunatum], entering a depression there with a quite large tuberculum. Then with a much larger convexity coming out of its lower [distalis] surface it enters a common depression made by the fifth wrist bone [os trapezium] together with the sixth [os trapezoideum]. But as a precaution lest this bone enter the depressions of other bones everywhere, and itself like a tyrant receive none, Nature carved out in it a conspicuous depression so that together with the second carpal bone (with which this depression is common) it might admit the great, rotund head of the seventh bone [os capitatum], easily the largest of them all. Thus the first bone is joined to the radius, the second carpal bone, the fifth, the sixth, and the seventh.
