What are lamellae in bone tissue?
Understand the Problem
The question is asking for the definition of lamellae in bone tissue and provides multiple-choice options. It is seeking to clarify what lamellae are among the options given.
Answer
Lamellae are layers of compact matrix around the Haversian canal in osteons, providing bone strength.
Lamellae in bone tissue are layers of compact matrix that form concentric rings around the Haversian canal within an osteon. They give compact bone its hardness and rigidity through a structured alignment of collagen fibers and mineralized matrix.

More Information
Lamellae are crucial for the mechanical properties of bones, as they ensure strength and stability by organizing collagen fibers in a parallel pattern, providing resistance against stress. They are found in both compact and spongy bone, but are more organized in compact bone.
Tips
One common mistake is confusing lamellae with lamella. Lamella is the singular form referring to one layer, while lamellae is the plural form.
