#1
What is the primary component of bone tissue?
Calcium phosphate
ExplanationMain mineral in bones, providing strength and rigidity.
#2
Which type of bone tissue is responsible for storing minerals, particularly calcium and phosphorus?
Compact bone
ExplanationDense bone tissue, stores minerals and provides support.
#3
Which type of bone tissue is also known as cortical bone?
Compact bone
ExplanationHard outer layer of bone, providing protection and support.
#4
What is the purpose of the periosteum?
To provide a site for muscle attachment
ExplanationOuter layer of bone, essential for muscle attachment and bone repair.
#5
Which vitamin is essential for proper bone mineralization?
Vitamin D
ExplanationCritical for calcium absorption and bone health.
#6
What is the primary component of the organic matrix of bone tissue?
Collagen fibers
ExplanationProvide flexibility and strength to bone structure.
#7
What is the function of osteoclasts in bone tissue?
Break down bone tissue
ExplanationCells responsible for bone resorption and remodeling.
#8
Which hormone regulates calcium levels in the blood and plays a key role in bone remodeling?
Parathyroid hormone (PTH)
ExplanationRegulates calcium homeostasis, stimulates bone resorption.
#9
Which type of bone tissue is highly vascularized and contains trabeculae?
Cancellous bone
ExplanationSpongy bone, with a network of trabeculae for strength.
#10
What is the function of osteocytes in bone tissue?
To sense mechanical stress and regulate bone remodeling
ExplanationMaintain bone matrix, involved in sensing and signaling.
#11
Which cell type is responsible for bone formation during growth and repair?
Osteoblast
ExplanationCells that build bone by secreting new matrix.
#12
Which hormone promotes bone growth and stimulates protein synthesis in osteoblasts?
Growth hormone
ExplanationRegulates growth, including bone growth and metabolism.
#13
What is the Haversian canal?
A canal that contains blood vessels and nerves
ExplanationMicroscopic channel providing nutrients to bone cells.
