Palmar Branch Deep Ulnar Artery

The palmar branch of the deep ulnar artery (ramus palmaris profundus) is one of the terminal branches of the ulnar artery. It departs from the ulnar artery at the level of the wrist and goes deep into the palm of the hand.

This artery passes between the tendons of the muscles that flex the fingers. Then it anastomoses with the branches of the radial artery of the same name, forming the palmar arch.

The palmar branch of the deep ulnar artery supplies blood to the muscles, joints and skin of the palmar surface of the hand. It plays an important role in ensuring normal blood flow and innervation of the hand and fingers.

Damage to this artery can lead to poor circulation in the palm and fingers, which requires timely surgical treatment.
