Editing Radius (bone) (section)

===Development===
The radius is [[ossified]] from ''three'' centers: one for the body, and one for each extremity. That for the body makes its appearance near the center of the bone, during the eighth week of [[fetal]] life.

Ossification commences in the lower end between 9 and 26 months of age.{{citation needed|date=November 2019}} The ossification center for the upper end appears by the fifth year.

The upper [[epiphysis]] fuses with the body at the age of seventeen or eighteen years, the lower about the age of twenty.

An additional center sometimes found in the [[radial tuberosity]], appears about the fourteenth or fifteenth year.
