Intraosseous distribution of the nutrient artery of the humerus in the dog and goat

ABSTRACT

Work was carried on twenty humeri, ten from dogs and ten from goats. Anatomical and angiographical studies in both animals revealed a single nutrient artery passing diagonally through the nutrient canal. On reaching the medullary cavity, the artery divided into an ascending and a descending branches. The latter, showed similar mode of division and pattern of distribution in both animals. In the dog, the ascending branch divided into two medullary arteries, while in the goat it detached three ones. In both dog and goat, the medullary arterial system detached centrifugally coursed cortical rami to the diaphyseal cortex
