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:
“Different persons growing up in the same language are like different bushes trimmed and trained to take the shape of identical elephants. The anatomical details of twigs and branches will fulfill the elephantine form differently from bush to bush, but the overall outward results are alike.”
—Willard Van Orman Quine (b. 1908)
“But a camel’s all lumpy
And bumpy and humpy—
Any shape does for me.”
—Charles Edward Carryl (1841–1920)
“It is only a short step from exaggerating what we can find in the world to exaggerating our power to remake the world. Expecting more novelty than there is, more greatness than there is, and more strangeness than there is, we imagine ourselves masters of a plastic universe. But a world we can shape to our will ... is a shapeless world.”
—Daniel J. Boorstin (b. 1914)
