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:
“‘A Shape all light, which with one hand did fling
Dew on the earth, as if she were the dawn,
And the invisible rain did ever sing
‘A silver music on the mossy lawn;”
—Percy Bysshe Shelley (1792–1822)
“Bid her paint till day of doom,
To this favour she must come.
Bid the merchant gather wealth,
The usurer exact by stealth,
The proud man beat it from his thought,
Yet to this shape all must be brought.”
—Francis Beaumont (1584-1616)
“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)
