Neurovasculature of the hand

Learning objectives:

After going through this study unit, you will be able to:

  1. Identify the main vessels of the hand and their supply areas.
  2. Name the nerves of the hand and become familiar with their origin.

Watch video

The arteries of the hand arise from the radial and ulnar arteries which form two arches (superficial and deep) that supply its digits, muscles and joints. The venous drainage mainly follows the arterial supply draining blood into the ulnar and radial veins, however it is augmented by an extensive dorsal venous network that carries the blood towards the basilic and cephalic veins of the forearm. The median and ulnar nerves innervate the muscles of the hand; the cutaneous supply also comes from these nerves as well as the radial nerve.

The following video tutorial will provide you with an overview of the arteries, veins, and nerves of the hand.
