**Structural Characteristics of Bones**

Bones in the human body are categorized into five main shapes: long, short, flat, irregular, and sesamoid bones.

- **Long Bones**: Longer than they are wide (e.g., humerus).  
- **Short Bones**: Roughly cube-shaped, like wrist and ankle bones (e.g., trapezium, a carpal bone).  
- **Flat Bones**: Thin and plate-like (e.g., sternum).  
- **Irregular Bones**: Complex shapes that don’t fit other categories (e.g., vertebra).  
- **Sesamoid Bones**: Embedded within tendons (e.g., patella).

Additional Bone Type:
- **Wormian (Sutural) Bones**: Tiny bones within cranial sutures.

**Bone Markings**: Includes projections, holes, and depressions that serve as points for attachment and form joints. Understanding these markings is crucial for studying axial and appendicular skeletons.

**Diagram Explanation**

- The diagram depicts a human skeleton highlighting examples of different bone types. 
  - **Figure a**: Shows the humerus as a representation of a long bone.
  - **Figure b**: Illustrates the trapezium as an example of a short bone.
  - **Figure c**: Depicts the sternum, classified as a flat bone.
  - **Figure d**: Highlights a vertebra as an irregular bone.
  - **Figure e**: Shows the patella, a typical sesamoid bone. 

These visuals help in understanding the variety in bone shapes and their characteristics.
