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:
“But virtue, as it never will be moved,
Though lewdness court it in a shape of heaven,
So lust, though to a radiant angel linked,
Will sate itself in a celestial bed
And prey on garbage.”
—William Shakespeare (1564–1616)
“But a camel’s all lumpy
And bumpy and humpy—
Any shape does for me.”
—Charles Edward Carryl (1841–1920)
“Surely among a rich man’s flowering lawns,
Amid the rustle of his planted hills,
Life overflows without ambitious pains;
And rains down life until the basin spills,
And mounts more dizzy high the more it rains
As though to choose whatever shape it wills....”
—William Butler Yeats (1865–1939)
