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 (such as the vertebrae protect the spinal cord), affording multiple anchor points for skeletal muscle attachment (as with the sacrum), and maintaining pharynx and trachea support, and ...
Irregular bones are normally compact and have different sizes and shapes than other bones in the human body. Irregular bones don't fall into the other categories of bones, notes Teach PE. The sacrum at the base of the spine and the mandible in the lower jaw are examples of irregular bones because they have non-uniform shapes.

An irregular bone is a bone that can not be grouped in to groups. The 4 groups are long, short, flat, or sesamoid bones. Some bones not classified into those 4 groups are the vertebrae, the sacrum ...
Types of Bones is a topic within the Skeletal System module of first-level courses in Human Biology, Anatomy & Physiology and similar entry-level courses for careers in the Health Sciences. Typical study or exam questions include giving examples of different types of bones e.g. long bones, short bones, flat bones, irregular bones, sesamoid bones and so on.
Sesamoid bones are usually short or irregular bones, embedded in a tendon. The most obvious example of this is the Patella (knee cap) which sits within the Patella or Quadriceps tendon. Other sesamoid bones are the Pisiform (smallest of the Carpals) and the two small bones at the base of the 1st Metatarsal.
What are irregular bones? Bones are a form of extremely specialized connective tissue, consisting of a mix of a dense organic matrix and inorganic mineral component. They are characterized by their hardness and mechanical resistance. Bones are segments of varying shape, size and density, all of which constitute to form the skeletal system. The surface of […]
An irregular bone is a type of bone classified according to its shape. Irregular bones tens to have complicated shapes that are neither long, short or flat. An example of an irregular bone is the atlas bone in the human neck.
The cube-shaped short bones include the carpals, tarsals, metacarpals, metatarsals, and phalanges. Sesamoid bones are small bones that are embedded in some tendons. Patella (kneecap) is an example of a sesamoid bone. Irregular bones, as the name suggests, have an irregular shape. Hyoid bone and the vertebrae are examples of irregular bones.
4. Irregular Bones Have Complex Shapes. Irregular bones vary in shape and structure and therefore do not fit into any other category (flat, short, long, or sesamoid). They often have a fairly complex shape, which helps protect internal organs. For example, the vertebrae, irregular bones of the vertebral column, protect the spinal cord.
