A nutrient canal is found in both long bones and in irregular bones.

A nutrient canal is canal through which the nutrient artery enters.

At the junction of the upper with the middle third of the bone is the nutrient canal, directed obliquely upward.

The linea aspera is perforated a little below its center by the nutrient canal, which is directed obliquely upward.

The fossa gives origin to the Iliacus muscle and is perforated at its inner part by a nutrient canal; below this there is a smooth, rounded border, the arcuate line, which runs anterior, inferior, and medial.

About its center is a slight impression for the insertion of the coracobrachialis muscle, and just below this is the entrance of the nutrient canal, directed downward; sometimes there is a second nutrient canal at the commencement of the radial sulcus.
