Shape
The radius has a body and two extremities. The upper extremity of the radius consists of a somewhat cylindrical head articulating with the ulna and the humerus, a neck, and a double tuberosity. The body of the radius is self-explanatory, and the lower extremity of the radius is roughly quadrilateral in shape, with articular surfaces for the ulna, scaphoid and lunate bones. The distal end of the radius forms a palpable point called the styloid process. Along with the proximal and distal radioulnar articulations, an interosseous membrane originates medially along the length of the body of the radius to attach the radius to the ulna.

Famous quotes containing the word shape:
“After that it came to my door. Now it lives here.
And of course: it is a soft sound, soft as a seal’s ear,
that was caught between a shape and a shape and then returned to me.”
—Anne Sexton (1928–1974)
“In the multitude of middle-aged men who go about their vocations in a daily course determined for them much in the same way as the tie of their cravats, there is always a good number who once meant to shape their own deeds and alter the world a little.”
—George Eliot [Mary Ann (or Marian)
“There’s nothing constant in the world,
All ebb and flow, and every shape that’s born
Bears in its womb the seeds of change.”
—Ovid (Publius Ovidius Naso)
