Anatomical terminology [edit on Wikidata]

All bones possess larger or smaller foramina (openings) for the entrance of the nourishing blood-vessels; these are known as the nutrient foramina, and are particularly large in the shafts of the larger long bones, where they lead into a nutrient canal, which extends into the medullary cavity.^[1] Along with veins the nutrient arteries pass through this canal. A nutrient canal is found in both long bones and in irregular bones. In long bones the nutrient canal is found in the shaft, and in irregular bones it is found in other locations.
