Study Notes
Classification of Bones
- Four major anatomical classifications: long, short, flat, and irregular.
- Long bones have the least amount of spongy bone relative to total volume.
Long Bones
- Definition: Longer than wide, playing key roles in movement and support.
- Examples: Humerus, Radius, Ulna, Metacarpals, Femur, Tibia, Metatarsals, Phalanges, Fibula.
Short Bones
- Definition: Cube-shaped; contain more spongy bone than compact bone, providing support and stability.
- Examples: Carpals (wrist bones), Tarsals (ankle bones), Patella (kneecap), Calcaneus (heel bone).
Flat Bones
- Definition: Generally thin and curved; consist of two layers of compact bone with spongy bone in between.
- Examples: Skull (cranium), Sternum, Scapula (shoulder blade), Ribs, Clavicle.
Irregular Bones
- Definition: Bones that do not fit into other classifications; often complex in shape.
- Examples: Vertebrae, Ilium, Ischium, Pubis (bones of the pelvis girdle).
