Final answer:
A fracture is a broken bone and can present with various symptoms. Healing involves the formation of hematoma and calli, with osteoclasts and osteoblasts rejuvenating bone tissue. Proper medical treatment is essential for correct healing of a fracture.
Step-by-step explanation:
There is a common myth that you can tell when a bone is fractured because there will be very localized pain over the break. However, the reality is that fractures can present with a variety of symptoms, and the presence or absence of pain is not a definitive indicator of a fracture. Moreover, it's important to understand that a fracture is a broken bone, and it requires proper medical treatment to heal correctly.
A fracture line will not necessarily terminate at an existing line fracture. However, in biology, specifically when discussing the maturation of bones, an epiphyseal plate progresses to an epiphyseal line in a growing bone. When a fracture heals, it may go through a process of remodeling where the external evidence of the fracture can disappear over time.
Common types of fractures include transverse, oblique, spiral, and greenstick, among others. The healing process involves the formation of a hematoma, followed by the development of internal and external calli. Osteoclasts and osteoblasts play crucial roles in resorbing dead bone and creating new bone to replace the cartilage in the calli, leading to complete healing.
