Definition

Noun: 1. A type of bone characterized by its thin, flattened shape: A "flat bone" is one of the five major types of bones in the human body, distinguished by being thin, flat, and often curved. They typically provide protection for internal organs and offer broad surfaces for muscle attachment. 2. A specific cut of beef: In butchery, particularly for beef, a "flat bone" can refer to a part of the sirloin adjacent to another bone structure.

Usage Examples

• The scapula (shoulder blade) and the sternum (breastbone) are examples of flat bones in the human skeleton.
• The ribs are classified as flat bones that protect the heart and lungs.
• The butcher recommended the flat bone steak for its flavor and texture.

Advanced Usage

• Anatomical context: In anatomy, "flat bone" is a formal classification. These bones often form through intramembranous ossification and consist of two thin layers of compact bone surrounding a layer of spongy bone (diploë).
  • Example: The cranial bones of the skull are flat bones that enclose and protect the brain.
