#1
What is the main component of bone matrix?
Collagen fibers
ExplanationCollagen fibers provide structural integrity to bone matrix.
#2
What is the function of osteoblasts?
Bone formation
ExplanationOsteoblasts are responsible for synthesizing and depositing new bone tissue.
#3
What is the function of osteoclasts?
Bone resorption
ExplanationOsteoclasts break down bone tissue during resorption, releasing minerals into the bloodstream.
#4
Which cell type is responsible for bone formation?
Osteoblasts
ExplanationOsteoblasts are responsible for synthesizing new bone tissue during bone formation.
#5
Which cell type is responsible for bone resorption?
Osteoclasts
ExplanationOsteoclasts break down bone tissue during resorption.
#6
What is the function of osteocytes?
Maintain bone matrix
ExplanationOsteocytes help regulate mineral concentration and maintain bone tissue.
#7
Which hormone stimulates osteoclast activity?
Parathyroid hormone
ExplanationParathyroid hormone increases osteoclast activity to release calcium into the bloodstream.
#8
Which vitamin is essential for the absorption of calcium in the intestine?
Vitamin D
ExplanationVitamin D enhances calcium absorption in the intestine, promoting bone health.
#9
What is the function of the canaliculi in bone tissue?
Exchange nutrients and waste
ExplanationCanaliculi facilitate the exchange of nutrients and waste between osteocytes and blood vessels.
#10
What is the function of the Haversian canal in compact bone?
Transport blood vessels
ExplanationHaversian canals in compact bone house blood vessels, providing nutrients and oxygen to bone cells.
#11
What is the function of the Volkmann's canals in compact bone?
Connect osteons
ExplanationVolkmann's canals in compact bone connect blood vessels and nerves between adjacent osteons.
