Study Notes
Primary Classification of Bones
- Bones are primarily classified based on their shape into four categories: long, short, flat, and irregular.
Elongated Bones
- Long bones are characterized by their elongated shape and are typically found in limbs, facilitating movement and support.
Flat Bones
- Flat bones have a thin, flattened shape and are generally involved in protecting underlying organs. These bones provide a broad surface for muscle attachment.
Irregular Bones
- Irregular bones possess a complex shape that does not fit into the other three categories. Examples include vertebrae and certain facial bones, providing unique functions based on their structure.
Light Structure Bones
- Spongy or cancellous bones are characterized by a light structure filled with marrow, enabling them to bear weight while minimizing mass.
