Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

The irregular bones are bones which, from their peculiar form, cannot be grouped as long, short, flat or sesamoid bones. Irregular bones serve various purposes in the body, such as protection of nervous tissue, affording multiple anchor points for skeletal muscle attachment, and maintaining pharynx and trachea support, and tongue attachment. They consist of cancellous tissue enclosed within a thin layer of compact bone. Irregular bones can also be used for joining all parts of the spinal column together. The spine is the place in the human body where the most irregular bones can be found. There are, in all, 33 irregular bones found here.
