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:
“I know that each stage is not going to last forever. I used to think that when he was little. Whenever he was in a bad stage I thought that he was going to be like that for the rest of his life and that Id better do something to shape him up. When he was in a good state, I thought he was going to be a perfect child and I would never have to worry; he was always going to stay that way.”
—Anonymous Parent of An Eight-Year-Old. As quoted in Between Generations by Ellen Galinsky, ch. 4 (1981)
“To know oneself, one should assert oneself. Psychology is action, not thinking about oneself. We continue to shape our personality all our life. If we knew ourselves perfectly, we should die.”
—Albert Camus (19131960)
“But her shape is the least of my madness; she has things by which it is more pleasing to die.”
—Propertius Sextus (c. 5016 B.C.)
