The deep palmar branch of ulnar artery is an ulnar artery branch division. It is responsible for the supply of the hypothenar muscles. It is at times referred to as either the 'profunda branch' or the 'deep volar branch.' The hypothenar muscles are a set of three muscles that establish the contour of the hand's hypothenar eminence. The ulnar nerve innervates all three of the muscles. The palmar branch travels deep into the palm all the way to the long flexor tendons. Upon arrival the branch engages in communication with the radial artery's deep palmar arch. The deep palmar branch of ulnar artery goes through the Opponens digiti minimi, which is a hand muscle that has a triangular shape. It also goes through the Flexor digiti quinti brevis and the Abductor digiti quinti muscles.
