Verified step by step guidance

Understand the classification of bones: Bones are classified into several categories based on their shapes and functions. The main categories are long bones, short bones, flat bones, sesamoid bones, and irregular bones.

Define irregular bones: Irregular bones are bones that do not fit into the other categories due to their complex shapes. They often have a variety of functions, including protection of nervous tissue and support.

Identify examples of irregular bones: Common examples of irregular bones include vertebrae, which protect the spinal cord, and certain facial bones.

Analyze the options given: Compare each option to the definition of irregular bones. The vertebra fits the description of an irregular bone due to its complex shape and function.

Conclude which bone is an irregular bone: Based on the analysis, the vertebra is accurately described as an irregular bone, while the scapula, femur, and sternum fit into other categories (flat, long, and flat bones respectively).
