18 Questions
How does the constant formation and destruction of bones contribute to bone plasticity?
By enhancing bone flexibility
What role do osteoclasts play in bone homeostasis?
They break down and resorb bone tissue
What materials are mobilized from the bone matrix during bone homeostasis?
Calcium, phosphate, and other minerals
What is the significance of bone constantly being formed and destroyed in bone homeostasis?
It allows bone to adapt to changing mechanical demands
One consequence of an imbalance in osteoblastic and osteoclastic activity is:
Decreased bone flexibility
What are the two main factors the body requires to maintain bone homeostasis?
Calcium and phosphate
What is the primary role of osteoclasts in bone tissue?
Breaking down and resorbing bone tissue
Which bone cell acts as stem cells and is responsible for producing new osteoblasts?
Osteogenic cells
If a bone has high collagen content but lacks hydroxyapatite, what would be its characteristic?
Very brittle
Which type of bone cell is considered the 'master' regulator of bone maintenance?
Osteocytes
What contribution do mineral salts make to hydroxyapatite in bone tissue?
Calcium phosphate
Which component of the extracellular matrix in bone tissue is responsible for its hardness?
Hydroxyapatite
What analogy best describes the function of trabecular bone in spreading force?
Spiral staircase
Which characteristic of trabecular bone allows it to resist forces from multiple directions?
Trabecular struts
What process is responsible for increasing the width of a bone through the addition of new bone matrix?
Appositional growth
Which cells are responsible for adding new bone matrix during bone remodeling?
Osteoblasts
What is the primary function of osteoclasts in bone remodeling?
Removing bone from the medullary cavity
Bone homeostasis is maintained through a balance between which two processes?
Osteoclast activity and bone formation
