The Arteria Nutritia, or nutritious artery of the humerus, arises high up from the brachial, below the superior profunda, and penetrates the oblique canal that may be observed on the inside of the humerus, taking the direction downwards through the compact tissue of the bone, towards the elbow-joint. It supplies the medullary membrane and cancellated structure of the bone, and anastomoses with its other nutritious arteries, which are much smaller, and enter at various points, particularly near the extremities. Professor Harrison relates a case in which an aneurism of this artery ensued on a fracture of the humerus, and amputation was deemed necessary.*
