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:
“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)
“And yonder in the gymnasts’ garden thrives
The self-sown, self-begotten shape that gives
Athenian intellect its mastery,
Even the grey-leaved olive-tree
Miracle-bred out of the living stone....”
—William Butler Yeats (1865–1939)
“Thus Kent, O princes, bids you all adieu;
He’ll shape his old course in a country new.”
—William Shakespeare (1564–1616)
