Bones of the Arm

they are the humerus, the radius and the ulna, as long as the word "arm" indicates the anatomical section between the shoulder and the wrist.

The bones of the arm are extremely relevant from an anatomical point of view: all three participate in the elbow joint; moreover, the humerus takes part in the shoulder joint and inserts muscles in the proximal portion of the upper limb, while the the radius and the ulna form the wrist joint and attach to the muscles of the distal section of the upper limb.
Like all bones in the human body, the bones of the arm can also be fractured.

more extensive (and less anatomically accurate) than the word "arm", the bones of the arm are the bone of the so-called anatomical arm (humerus) and the bones of the forearm (radius and ulna).

; in human anatomy, long bones are bones developed in length, characterized by a narrow central portion (called the body or diaphysis) and two bulky ends (called the proximal epiphysis and distal epiphysis).
