APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Irregular Bones They are primarily spongy bone that is covered with a thin layer of compact bone. The vertebrae and some of the bones in the skull are irregular bones.

Detailed explanation-2: -The “irregular bones” refers to bones that perform various bodily functions, including protecting nerve tissue and providing support for the pharynx and trachea. They belong to the group of vertebrae and hip bones (coaxial bone) and are categorised as neither long, short, nor flat.

Detailed explanation-3: -Examples of flat bones are the sternum (breast bone), ribs, scapulae (shoulder blades), and the roof of the skull (Figure 1). Irregular bones are bones with complex shapes. These bones may have short, flat, notched, or ridged surfaces. Examples of irregular bones are the vertebrae, hip bones, and several skull bones.

Detailed explanation-4: -Irregular Bones An irregular bone is one that does not have any easily characterized shape and therefore does not fit any other classification. These bones tend to have more complex shapes, like the vertebrae that support the spinal cord and protect it from compressive forces.
