All bones possess larger or smaller foramina (openings) for the entrance of 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. The nutrient canal (foramen) is directed away from the growing end ...
A sesamoid bone is a small, round bone that, as the name suggests, is shaped like a sesame seed.

The sesamoid bones protect tendons by helping them overcome compressive forces.

Galleasses usually carried more sails than galleys and had far more firepower; [3] a galley caught in a galleass's broadside was in great danger, since it exposed to a large amount of gunfire. Relatively few galleasses were built—one ...
