Long bone/micro anatomy of bone

Front

Where does growth (elongation) in bone take place?

Back

Growth in bone takes place at the epiphyseal plate.

Front

What is the function of red bone marrow?

Back

Red bone marrow functions in the creation of blood cells.

Front

What is the periosteum?

Back

The periosteum is a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.

Front

What are lamellae?

Back

Lamellae are the concentric (circular) rings that compose an osteon.

Front

What is the role of osteoblasts?

Back

Osteoblasts are cells that synthesize bone and are responsible for bone growth.

Front

What is the endosteum?

Back

The endosteum is a thin membrane lining the inner surface of the bone, including the medullary cavity.

Front

What is the function of articular cartilage?

Back

Articular cartilage provides a smooth, lubricated surface for joint movement and absorbs shock.

Front

What is the medullary cavity?

Back

The medullary cavity is the central cavity of bone shafts where red and yellow bone marrow is stored.

Front

What is the difference between red and yellow bone marrow?

Back

Red bone marrow produces blood cells, while yellow bone marrow stores fat.

Front

What is the significance of the epiphyseal plate?

Back

The epiphyseal plate is crucial for the lengthening of bones during growth.
