Anatomic characterization of the radial and ulnar nutrient arteries in humans

摘要

Background: The localization of nutrient foramens has been extensively studied in humans and other vertebrate animals. However, accurate information on the origin and extraosseous course of the nutrient arteries in some types of long tubular bones is lacking. Terminologia Anatomica, the international standard on human anatomic terminology, lists the radial nutrient artery (RNA) and the ulnar nutrient artery (UNA) as branches of the radial and ulnar arteries, respectively. Anatomy textbooks published in both German and English-speaking countries regard both the RNA and UNA as branches of the anterior interosseous artery.
