The distal end of your arm refers to the part of your arm that is away from the point of attachment. This would mean the lower arm/wrist.
The ulnar nerve is one of the three main nerves in your arm. It travels from your neck down into your hand. A compromised ulnar nerve could result in decreased sensation in the arm and the inability to adduct (pull towards the middle) and abduct (spread out) the fingers.
