Match the appropriate name with the structure in the figure.
2. Lamella

Verified step by step guidance

1. Step 1: Understand the term 'Lamella' in the context of bone anatomy. A lamella is a thin layer or plate of bone matrix in compact bone tissue.
2. Step 2: Identify the structures in the image. The image shows a cross-section of compact bone with labeled parts: 'a' points to a group of concentric rings, 'b' points to a single ring, 'c' points to a canal, 'd' points to small spaces, and 'e' points to a larger canal.
3. Step 3: Recognize that lamellae are the concentric rings of bone matrix surrounding the central canal in an osteon. These rings are labeled as 'b' in the image.
4. Step 4: Confirm that 'b' corresponds to the lamellae because they form the layered structure of compact bone around the central canal.
5. Step 5: Conclude that the correct match for 'Lamella' in the figure is the structure labeled 'b'.

Key Concepts

Lamella

Lamellae are concentric layers of bone matrix found in compact bone. They form the structural units called osteons, providing strength and resilience to the bone. Each lamella surrounds a central canal containing blood vessels and nerves.

Osteon Structure

An osteon is the fundamental functional unit of compact bone, consisting of concentric lamellae arranged around a central (Haversian) canal. This structure facilitates nutrient and waste exchange through blood vessels and nerves.

Bone Cells and Canals

Osteocytes are mature bone cells housed in lacunae between lamellae, connected by canaliculi for communication. The central canal contains blood vessels and nerves, while perforating canals connect osteons, ensuring bone vitality.
