Quick question-

How do the arms have more bones than the chest? You have each of the separate rib-bones, counting many more than the arms.

Please explain? Q_Q

The arms also include the hand which is made up of a lot of small bones, the carpals, metacarpals, and the phalanges. In total there are 64 bones in the Arm, 27 alone in the hand. The chest only has 26 bones. Hope this answers your question.,additional%20cervical%20ribs%20in%20humans.

Can you please add that the arms include the hands? I had the same logic as Kazakhstankitten and excluded hands and feet when putting in the answer. Thanks

Agree with above as there are different definitions of arm (and leg). First line of the wiki arm page says "In human anatomy, the arm is the part of the upper limb between the shoulder joint and the elbow joint." Maybe you should specify, otherwise it's a case of guessing which definition you're using. Great quiz though. Had never thought about the life span of a red blood cell - interesting!

In common usage, the arm extends through the hand. It can be divided into the upper arm, which extends from the shoulder to the elbow, the forearm which extends from the elbow to the hand, and the hand. Also from Wiki ;-)

I have changed the answers slightly to avoid more discussion :-).

The chest has 37 bones, not 26. 12 ribs per side = 24, 12 thoracic vertebrae and a sternum. The arm has 32, a clavicle, scapula, humerus, radius and ulna (makes 5) plus 8 carpal bones, 5 metacarpals and 14 phalanges. Your answer of 64 suggests that you are including both arms but the question says "arm" singular. So the answer should be chest.
