Verified step by step guidance

Understand the structure of an osteon, which is the fundamental functional unit of compact bone.

Recognize that each osteon consists of a central canal, also known as the Haversian canal, which contains blood vessels and nerves.

Identify that surrounding the central canal are concentric rings of calcified matrix.

These concentric rings are known as lamellae, which are layers of bone matrix that provide strength and support.

Differentiate lamellae from other structures such as lacunae (small spaces containing osteocytes), trabeculae (spongy bone structures), and canaliculi (tiny channels connecting lacunae).
