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:
“Man is not merely the sum of his masks. Behind the shifting face of personality is a hard nugget of self, a genetic gift.... The self is malleable but elastic, snapping back to its original shape like a rubber band. Mental illness is no myth, as some have claimed. It is a disturbance in our sense of possession of a stable inner self that survives its personae.”
—Camille Paglia (b. 1947)
“After that it came to my door. Now it lives here.
And of course: it is a soft sound, soft as a seal’s ear,
that was caught between a shape and a shape and then returned to me.”
—Anne Sexton (1928–1974)
“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)
