Forearm bones

from Wikipedia, the free encyclopedia
When both bones in the forearm are broken, it is called a complete forearm fracture.

The forearm bones ( Ossa antebrachii ) belong to the upper extremity (arm of the human being) or fore limb of vertebrates.


The two long forearm bones belong to the forearm bones of humans, other mammals as well as birds and reptiles

These bones are tubular bones . The ulna is "thick" at the top and the spoke at the bottom; because the ulna and the humerus form the actual elbow joint and the spoke carries the wrist (the proximal carpal bones). The load is transferred (e.g. during push-ups) through the interosseous membrane between the two bones.

"Complete forearm fractures" (of both bones) are more common in children than adults.
