The is Radius is the outer and shorter bone of the
forearm (lower-arm). It partially rotates around the ulna, permitting
pronation and supination of the hand.
The location of the Radius is indicated
in the diagram opposite.
See the Revision page about Bones
of the Hand, Wrist and Lower-Arms for further information including
a larger fully labelled diagram. This may be particularly interesting study/revision material for students
following courses in Reflexology
because such courses generally require a good basic knowledge of the skeletal
structures of the hands and feet.
