Understanding Longitudinal Bone Growth

What is the process called in which long bones lengthen?

• Transverse growth

• Longitudinal growth

• Radial growth

• Circumferential growth

What is the layer of cartilage found at the metaphysis called?

• Articular cartilage

• Epiphyseal/growth plate

• Periosteum

• Endosteum

During bone growth, where is new cartilage formed?

• On the diaphyseal side of the plate

• On the epiphyseal side of the plate

• In the bone marrow

• On the periosteal surface

What happens to older cartilage during bone growth?

• It becomes ossified on the diaphyseal side of the plate

• It remains unchanged

• It becomes ossified on the epiphyseal side of the plate

• It turns into bone marrow

When does bone growth stop?

• When new cartilage is continuously formed

• When cartilage formation ceases and all is replaced by bone

• When the bone reaches a certain length

• When the periosteum thickens

What remains of the growth plate in fully grown adults?

• A thick layer of cartilage

• A thin epiphyseal line

• A dense bone layer

• A hollow cavity

Which side of the growth plate does ossification occur during bone growth?

• Epiphyseal side

• Diaphyseal side

• Both sides equally

• Neither side

What is the primary function of the epiphyseal/growth plate?

• To protect the bone marrow

• To facilitate longitudinal growth of bones

• To store minerals

• To provide a surface for muscle attachment

What is the term used for the process of cartilage turning into bone?

• Calcification

• Ossification

• Mineralization

• Chondrification

Which of the following statements is true about the epiphyseal line in adults?

• It is a thick layer of cartilage

• It indicates that bone growth has stopped

• It is responsible for bone lengthening

• It is found only in children
