Back

It contains blood vessels and nerve fibers.

Front

What is a compound fracture?

Back

A compound fracture is when the broken bone is exposed to the outside.

Front

What are lacunae in bone tissue?

Back

Lacunae are small cavities in bone tissue where osteocytes are found.

Front

What factors determine where bone matrix is remodeled?

Back

The stresses of gravity and muscle pull on the skeleton.

Front

What is the tiny canal that connects central canals to lacunae in compact bone?

Back

Canaliculus.

Front

What are osteoblasts?

Back

Osteoblasts are cells that form new bone tissue.

Front

What are osteoclasts?

Back

Osteoclasts are cells that break down bone tissue.

Front

What is the role of Haversian canals?

Back

Haversian canals contain blood vessels and nerves, providing nutrients to bone.

Front

What is the difference between compact bone and spongy bone?

Back

Compact bone is dense and forms the outer layer of bones, while spongy bone is lighter and found inside bones.

Front

What is the significance of the periosteum?

Back

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