Them Bones, Them Dry Bones ...
 

The hand bone's connected to the wrist bone. The wrist bone's connected to the arm bone, etc. Those bones gonna get up and walk around. Let's hear the word of the Lord.

BillyMac has left the building.

Well, being a joint, the wrist is comprised of the hand and the forearm. :D

Non wise-*** answer - you don't have an X-ray machine on the court, so go by your best judgement. If a coach wants to argue hand vs. arm, I'm not listening for more than about 1.3 seconds.

The arm bones are composed of the radius (thumb side) and ulna (pinky side) for the forearm and the humerous in the upper arm. The humerous' connected to the shoulder, which I think is directly connected to the clavical.

One More Time ...
 

Let's hear the word of the Lord.

As you can see, the head of the humerous is actually connected to the Scapula by resting in the Glenoid. The connection is made by muscle, ligaments and tendons. The Clavical and the Acromion are the other bones that makes up the bones of the shoulder.

The shoulder is the most complicated joint in the body, as when you raise your arm above your head (say, when calling a foul :D ) the humerous may actually pull away slightly from the Glenoid. It's really pretty amazing. And it makes no sense.

Where is this anatomy class going? The question was about the HAND! We're all the way up to the shoulder!!! ;)

Sounds like you're channeling your inner coach :D

Is The Hand Part Of The Ball ???
 

Here's a photo of Chuck making the correct call:
