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:
“Caught by the spectacle my mind turned round
As with the might of waters; an apt type
This label seemed of the utmost we can know,
Both of ourselves and of the universe;
And, on the shape of that unmoving man,
His steadfast face and sightless eyes, I gazed,
As if admonished from another world.”
—William Wordsworth (1770–1850)
“Autonomy means women defining themselves and the values by which they will live, and beginning to think of institutional arrangements which will order their environment in line with their needs.... Autonomy means moving out from a world in which one is born to marginality, to a past without meaning, and a future determined by others—into a world in which one acts and chooses, aware of a meaningful past and free to shape one’s future.”
—Gerda Lerner (b. 1920)
“This whole day have I followed in the rocks,
And you have changed and flowed from shape to shape,
First as a raven on whose ancient wings
Scarcely a feather lingered, then you seemed
A weasel moving on from stone to stone....”
—William Butler Yeats (1865–1939)
