Where are lamellae typically located in animal tissues?
A
Within the bone matrix, surrounding osteons
B
On the surface of epithelial cells
C
Inside the cytoplasm of muscle cells
D
In the extracellular matrix of cartilage
Verified step by step guidance1
Understand the term 'lamellae': Lamellae are thin layers or sheets of tissue, often found in specific structural arrangements in certain types of tissues.
Recall the structure of bone tissue: In compact bone, lamellae are concentric rings of bone matrix that surround the central canal of osteons (also known as Haversian systems).
Eliminate incorrect options: Lamellae are not found on the surface of epithelial cells, as epithelial cells have specialized structures like microvilli or cilia. Similarly, lamellae are not located inside the cytoplasm of muscle cells, as muscle cells contain myofibrils and sarcomeres for contraction. Lastly, while cartilage has an extracellular matrix, it does not contain lamellae; instead, it has chondrocytes embedded in lacunae.
Focus on the correct location: Lamellae are specifically located within the bone matrix, where they form part of the osteons, providing structural support and strength to compact bone.
Conclude: Based on the above reasoning, the correct answer is 'Within the bone matrix, surrounding osteons.'
