Study Notes
- Bones are classified by shape
Classification Description
- Long bones are longer than they are wide.
- Examples: humerus, femur, tibia, and fibula.
- Short bones are nearly equal in length and width, and are somewhat cube-shaped.
- Examples: carpals and tarsals.
- Flat bones are thin, broad, and large.
- They provide a surface area for muscle attachment.
- Examples: scapula, cranial bones, sternum, and ribs.
- Irregular bones have complex shapes that do not easily fit into other categories.
- Examples: facial bones, vertebrae, and the pelvis.
- Sesamoid bones are small bones situated within tendons.
- Example: patella
