There are four bones in the arm of an adult human body. These are the scapula, the humerus, the radius and the ulna. Each of these bones is wide at either of its two ends and tapers and becomes skinnier in the middle. This helps to give it strength at the point where it meets another bone.

The scapula is a large bone. It is triangular in shape and located on the upper back corner of either side of the rib cage. The humerus is located above the elbow and the radius and the ulna are located below the elbow.

At the ends of the radius and the ulna are eight small bones that make up the wrist. The centre of the hand has five bones, and each of the fingers, except the two thumbs, have three bones each. Each thumb has two bones apiece. Therefore there are a total of 54 bones, which are 27 bones in each arm. There are six large bones in the leg of an adult human body. These are the pelvis, the femur, the patella, the tibia, the fibula and the talus.

The femur is the longest bone in the body. The pelvis is a circular group of bones, in the structure of a bowl. This supports the spine. The triangular bone at the knee is known as the patella (kneecap). The tibia and fibula are the two bones that are located below the knee.

The three bones of the leg, like the three bones of the arm are wider at the ends that in the middle, which gives them strength. There is a large bone in the foot called the talus, next to which are six smaller bones. There are five bones in the foot, just like in the hands. Each of the eight small toes has three bones each and the two big toes have two bones each. This takes the total of the leg bones to 52, that are 26 in either leg.

Technically the arm in anatomy is the part between the Shoulder and the Elbow and the only bone there is the Humerus.
The Forearm contains two bones called the Radius and the Ulna.
The hands have many bones but they are not part of the arm.

An adult human has three bones in one arm and three bones in one leg.  The kneecap is not considered a true bone, but, instead is called a sesamoid bone, formed from the rubbing of the tendon of the quadriceps muscle over the knee joint.
