Endochondral Ossification

Front

What is endochondral ossification?

Back

Endochondral ossification is the process by which bone tissue is created from hyaline cartilage, primarily during the development of long bones.

Front

What is the primary ossification center?

Back

The primary ossification center is the region in the center of the diaphysis of long bones where bone tissue begins to replace hyaline cartilage.

Front

What is the epiphyseal plate?

Back

The epiphyseal plate, also known as the growth plate, is a band of cartilage in the epiphysis where secondary ossification occurs, allowing for bone growth.

Front

What indicates that a person has stopped growing?

Back

The presence of an epiphyseal line in long bones indicates that a person has stopped growing, as it signifies the closure of the growth plate.

Front

What happens to hyaline cartilage during endochondral ossification?

Back

During endochondral ossification, hyaline cartilage is gradually replaced by bone tissue.

Front

Why is the yellow marrow in spongy bone yellow?

Back

The yellow marrow in spongy bone is yellow because it stores fat.

Front

What is the role of osteoblasts in bone formation?

Back

Osteoblasts are cells responsible for the formation of new bone by synthesizing and secreting the bone matrix.

Front

What is the difference between primary and secondary ossification centers?

Back

Primary ossification centers are located in the diaphysis and form first, while secondary ossification centers are located in the epiphyses and form later.

Front

What is the significance of the medullary cavity?

Back

The medullary cavity is the central cavity of long bones that contains bone marrow, which is involved in the production of blood cells.

Front

What is the function of osteocytes?

Back

Osteocytes are mature bone cells that maintain bone tissue and communicate with other bone cells to regulate bone remodeling.
