The word parts in “osteogenic” can be interpreted as which of the following?

• Bone + break down

• Bone + produce

• Bone + store

• Bone + move

Where are osteogenic cells primarily located in a long bone?

• In the marrow cavity and articular cartilage

• In the periosteum and endosteum

• Inside osteons only

• Within ligaments around the bone

Which best defines the role of osteoblasts in the skeletal system?

• They break down old bone tissue

• They build new bone by forming osteoid

• They transport oxygen in blood

• They connect muscles to bones

What is the bone matrix produced by osteoblasts called?

• Periosteum

• Osteoid

• Marrow

• Cartilage

Which combination correctly lists main components of osteoid?

• Calcium, collagen, and water

• Iron, hemoglobin, and platelets

• Keratin, lipids, and melanin

• Glucose, starch, and cellulose

After osteoblasts become trapped in the matrix they produce, what do they turn into?

• Chondrocytes

• Osteoclasts

• Osteocytes

• Fibroblasts

The term part “blast” in osteoblast most closely means which of the following?

• Bone

• Bud/sprout

• Break

• Blood

Which reasoning best explains why osteoblasts are found at epiphyseal plates and along the periosteum?

• These regions store fat for energy.

• Bones grow longer at epiphyseal plates and wider along the periosteum.

• These are the strongest parts of the bone.

• Blood vessels only enter the bone at these sites.
