The artery that enters the hand anterior to the flexor retinaculum between the pisiform and the hook of the hamate via the ulnar canal (Guyon canal) is the Ulnar Artery.

Here are the steps of how the Ulnar Artery reaches the hand:

1. The Ulnar Artery originates from the Brachial Artery in the upper arm.
2. It then travels down the forearm, running along the ulna bone.
3. As it reaches the wrist, it passes over the transverse carpal ligament (also known as the flexor retinaculum).
4. It enters the hand between the pisiform and the hook of the hamate bones.
5. It does this via a small tunnel known as the Guyon Canal or Ulnar Canal.
6. Once in the hand, it gives off several branches to supply blood to the various structures of the hand.
