Quick Answer: When the epiphyseal plate is replaced by bone,?

When the epiphyseal plate is replaced by bone and becomes an epiphyseal line?

The epiphyseal plate allows the diaphysis of the bone to increase in length until early adulthood. When growth stops, the epiphyseal plate cartilage is replaced with bone, then becoming the epiphyseal line. compact bone, is one of the two types of osseous tissue that form bones.

What happens to the epiphyseal plate at adulthood?

The condrocytes produce cartilage on one side of the plate and push the end of the bone up. The other side of the epiphyseal plate gradually becomes calcified. Once a person reached adulthood and the bones have reached maximum length, and the whole plate gets calcified.

At what age do epiphyseal plates close?

This replacement is known as epiphyseal closure or growth plate fusion. Complete fusion happens on average between ages 15–20 for girls (with the most common being 15–18 years for girls) and 17–24 for boys (with the most common being 18–22 years for boys).

What are the stages of bone development?

The process of bone formation is called osteogenesis or ossification. After progenitor cells form osteoblastic lines, they proceed with three stages of development of cell differentiation, called proliferation, maturation of matrix, and mineralization.

What happens if the epiphyseal plate is damaged?

Growth plate fractures often need immediate treatment because they can affect how the bone will grow. An improperly treated growth plate fracture could result in a fractured bone ending up more crooked or shorter than its opposite limb. With proper treatment, most growth plate fractures heal without complications.
