A type of fracture that occurs in children, where the bone bends and cracks on one side without breaking completely through, similar to bending a green twig.

Front

What bones are included in the Axial Skeleton?

Front

What are perforating (Volkmann's) canals?

Canals that run perpendicular to the long axis of the bone, allowing blood vessels and nerves to penetrate the bone.

Front

What is the function of osteoblasts?

Back

Osteoblasts are cells responsible for bone formation and mineralization.

Front

What is the role of osteoclasts in bone healing?

Back

Osteoclasts are cells that break down bone tissue, helping to remodel and reshape the bone during healing.

Front

What is a Spiral fracture?

Back

A fracture that occurs when a twisting force is applied to a bone, resulting in a helical break.

Front

What is the difference between the Axial and Appendicular Skeleton?

Back

The Axial Skeleton consists of the skull, vertebrae, and ribs, while the Appendicular Skeleton includes the limbs and pelvic girdle.

Front

What is a Compression fracture?

Back

A fracture that occurs when the bone is crushed, often seen in vertebrae due to osteoporosis.
