What are Compact Bones
Bones in the human body that have approximately equal width and length are considered compact bones.
These bones typically have a cuboid shape and are primarily composed of spongy bone, with a thin outer layer of compact bone.
Compact Bones Found in the Body
Wrist bones (carpal)
- Scaphoid
- Lunate
- Triquetrum
- Pisiform
- Trapezium
- Trapezoid
- Capitate
- Hamate
Ankle bones (tarsal)
- Talus
- Calcaneus
- Navicular
- Cuboid
- Medial cuneiform
- Intermediate cuneiform
- Lateral cuneiform
The patella or kneecap is at times classified as a compact bone due to its shape, although it is more commonly recognized as the largest sesamoid bone in the human body.
Functions
These bones provide stability and compactness to the wrist and ankle regions. While they have limited mobility, they permit a restricted range of movement in the wrist and ankle.
