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:
“What man dare, I dare.
Approach thou like the rugged Russian bear,
The armed rhinoceros, or the Hyrcan tiger;
Take any shape but that, and my firm nerves
Shall never tremble. Or be alive again
And dare me to the desert with thy sword.”
—William Shakespeare (1564–1616)
“There are moments when very little truth would be enough to shape opinion. One might be hated at extremely low cost.”
—Jean Rostand (1894–1977)
“It is as real
as splinters stuck in your ear. The noise we steal
is half a bell. And outside cars whisk by on the suburban street
and are there and are true.
What else is this, this intricate shape of air?
calling me, calling you.”
—Anne Sexton (1928–1974)
