The human forearm consists of two bones.
These two bones are called the ulna and the radius.
And the wrist part, which connects the hand and the arm, is made up of several small bones.
In anatomy, these wrist bones are referred to as the trapezium, trapezoid, scaphoid, lunate, triquetrum, hamate, pisiform, and capitate.
These bones make up the flexible human wrist.
Among these bones, the scaphoid, lunate, and triquetrum are closely adjacent to the long ulna and radius of the forearm. The space between them is called the intercarpal joint space.
The ulna and radius are relatively hard, at least a small paring knife, under these circumstances without enough force, can never sever the ulna and radius.
