Skeletal System and Bone Characteristics

Front

Describe the characteristics of the spiral fracture.

Back

A spiral fracture is characterized by a helical break in the bone, often caused by a twisting force.

Front

Describe the characteristics of the comminuted fractures.

Back

Comminuted fractures involve the bone being broken into multiple pieces.

Front

Describe the characteristics of the greenstick fracture.

Back

A greenstick fracture is an incomplete fracture where the bone bends and cracks on one side without breaking completely, the condition is pertinent to children only, as in adults it is called something else.

Front

Describe the features of the appositional growth.

Back

Appositional growth refers to the increase in the diameter of bones through the addition of new bone tissue.

Front

Name the cells involved in interstitial growth.

Back

Chondrocytes are the cells involved in interstitial growth.

Front

Distinguish between Intramembranous ossification and endochondral ossification.

Back

Intramembranous ossification occurs directly within mesenchyme, while endochondral ossification involves a cartilage model.

Front

Distinguish between epiphyseal plate and epiphyseal line.

Back

The epiphyseal plate is a growth plate where bone lengthening occurs, while the epiphyseal line is the remnant of the plate after growth has ceased.

Front

Name the basis of classification of bones.

Back

Bones are classified based on their shape: long, short, flat, irregular, and sesamoid.

Front

What is the function of periosteum?

Back

The periosteum serves as a protective layer and provides a surface for muscle attachment.

Front

What is osteoid?

Back

Osteoid is the unmineralized organic component of bone matrix.
