Final answer:
Option (A), When a bone partially fractures on one side, it is known as a greenstick fracture. This type of fracture is common among children due to the flexibility of their still-growing bones.
Step-by-step explanation:
Types of Bone Fractures
When only one side of the bone breaks, it is known as a greenstick fracture. A greenstick fracture is a type of bone fracture typically seen in children whose bones are still growing and are more flexible. Unlike adults whose bones tend to break completely when subjected to a forceful impact, children's bones can partially fracture on one side while bending on the other.
Other common types of fractures include transverse, spiral, comminuted, impacted, open (or compound), and closed (or simple). Fracture healing involves the formation of a hematoma, followed by calli that eventually unite, and the bone is remodeled and healed completely with the help of osteoclasts and osteoblasts.
