Ossification (osteogenesis) is the process of:

• Making a cartilage model of the fetal bone.

• Bone destruction to liberate calcium.

• Bone formation.

• Making collagen fibers for calcified cartilage.

The tubular shaft forming the long axis of long bones is known as:

• Diaphysis

• Epiphysis

• Trabeculae

• Epiphyseal plate

Bones are constantly undergoing resorption (breaking down of bone) for various reasons. Which of the following cells accomplishes this process:

• Osteoclast

• Osteocyte

• Osteoblast

• Osteogenic cell

The process of bones increasing in THICKNESS (widthwise) due to increasing the number of osteons in the bone is known as:

• Closing of the epiphyseal plate

• Concentric growth

• Interstitial growth

• Appositional growth

The central (Haversian) canal that runs through the core of each osteon is the site of:

• Cartilage and interstitial lamellae

• Yellow marrow and spicules

• Adipose tissue and nerve fibers

• Blood vessels and nerve fibers

Yellow bone marrow contains a large percentage of:

• Fat

• Elastic tissue

• Blood-forming cells

• Periosteum
