The Upper Arm is made of one bone, the Humerus.
There are therefore 2 Humerus bones in any mammalian skeleton.
There is only one bone in the upper arm - the humerus.
3 in each arm
Upper arm = Humerus Lower arm = Ulna and Radius
There are 3 bones in the arm. The forearm has 2 bones, the radius and ulna. The upper arm has one bone, the humerus.
3, the upper arm [humerus] the forearm [radius and ulna].
Three: the humerus (upper arm), ulna and radius (lower arm).
There are two bones in the upper arm: the humerus and the ulna. The humerus is the long bone that runs from the shoulder to the elbow, while the ulna is one of the two bones in the forearm, not the upper arm.
The humerus is a single bone. It is the only bone in the upper arm and one of the largest bones in the body.

The upper limb.
Upper: humerus. Lower: Radius and ulna
No. The 3 main bones of the arm - namely, the humerus, ulna and radius - are all long bones.
