During routine dissection for the first MBBS students, we observed that the radial artery was absent in the right upper limb of a 70 years old, donated embalmed male cadaver in the Department of Anatomy, K.J. Somaiya Medical College, Sion, Mumbai, India. In the lower part of the arm, brachial artery divided into ulnar and common Interosseous artery. Anterior interosseous artery was large in size. Deep to pronator quadratus, it turned laterally and reached the dorsum of the hand, where its lateral branch supplied the thumb and index finger and its medial branch dipped into the palm at the second inter metacarpal space. Superficial palmar arch was absent. Digital arteries from the medial and lateral branches of ulnar artery supplied the fingers. Embryological basis is presented.
