Multiple Choice

Which statement regarding osteons is false?

Osteons contain a central canal that houses blood vessels and nerves.

Osteons are primarily found in spongy bone.

Osteons are composed of concentric lamellae surrounding a central canal.

Osteons are the structural units of compact bone.

Verified step by step guidance

Understand the structure of an osteon: Osteons, also known as Haversian systems, are cylindrical structures that are the fundamental functional units of compact bone.

Identify the components of an osteon: Each osteon consists of concentric layers of calcified matrix called lamellae, which surround a central canal (Haversian canal) that contains blood vessels and nerves.

Differentiate between compact and spongy bone: Compact bone is dense and forms the outer layer of bones, while spongy bone, also known as cancellous bone, is lighter and found inside bones, characterized by a porous, trabecular structure.

Recognize the location of osteons: Osteons are primarily found in compact bone, not in spongy bone. This is a key distinction in understanding bone structure.

Evaluate the statements: Given the information, the false statement is that osteons are primarily found in spongy bone, as they are actually found in compact bone.
